    Reflection on reflection in action: A case study of growers conception of irrigation strategies in pot plant production2009In: AI & Society: The Journal of Human-Centred Systems and Machine Intelligence, ISSN 0951-5666, E-ISSN 1435-5655, Vol. 23, no 4, 545-558 p.Article in journal (Refereed)
    Abstract [en]

    A case study of growers conception of irrigation strategies indicates that pot plant growers in Scandinavia base their management approaches on experientially based art. The study also indicates that there is a gap between experientially based art and available greenhouse technology. In order to standardize production and produce quality, both the grower's experience and available technology should be taken into account. In order to achieve this, the present study proposes to arrange reflection on reflection in action with a group of growers by means of the dialogue seminar method. The concept of reflection on reflection in action is novel to horticultural practice. Therefore, we suggest future inter- and multidisciplinary research within this domain.

    Prospects of dialogue-inspired methods as tools for knowledge transfer: Technology for sustainable horticulture meets experiential knowledge communities2009In: Acta Horticulturae, International Society for Horticultural Science , 2009, 27-32 p.Chapter in book (Refereed)
    Abstract [en]

    Horticultural production systems have a large environmental impact. Legislation, ordinances and quality assurance systems provide guidelines for implementing sustainable production technologies in horticulture at a higher level. Horticultural research has compiled solutions to improve sustainable production. Despite of regulations, hands-on information, solid scientific data on sustainable strategies for horticulture and a general environmental awareness, there is reluctance in considering sustainable technology and reorganizing horticultural production lines. Knowledge within commercial horticulture is situated knowledge; this means experience consolidated within the branch is a precondition for application. However, knowledge on sustainable technology follows the tradition of natural sciences and technology. Another crucial aspect concerns the path from understanding sustainable technology to putting it into action. Reflection on reflection in action as an activity aims at producing a good verbal description of reflection in action, which can be shared with other people. While reflection in or on action is primarily private the notion of reflection on reflection in action is tied to the fact that learning and experience exchange are social activities that proceed in different communities of practice. Dialogue-inspired methods may act as a tool. In the present paper we discuss the dialogue seminar and Socratic dialog methods to bridge the gap between scientific and technological progress in horticulture and horticultural practice to be employed in horticultural extension.

    Bakom Ladan: En skiss eller två på en hälsoträdgård på Wij Trädgårdar2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    The research in the interdisciplinary field of natural-human-health-design has in recent decades gainedmomentum and led to new or new-old ways of thinking and acting in terms of planning and design of outdoorenvironments with the aim of health promotion. Concrete concept models and design guides have begun toemerge as a result of this research.The purpose of this work is to use these guides to develop a design proposal for a supposed health garden,with Wij Trädgårdar in Ockelbo as a base. This has been done in the form of a process description. The targetgroup for the design proposal is long-term unemployed and people who have come to Sweden as refugees.Since the specific design recommendations could not be found for the selected target group, the main materialwas general guidelines for health gardens in combination with guidelines for health gardens directed to targetgroups with stress-related problems, which is a broad target group for which there are relatively much currentresearch.The result is a process description of the progression towards a sketch on a health garden, designed for aspecific spot on Wij Trädgårdar, but available for use in other locations, provided adjustments is made to thespecific location. The sketch is supplemented with plant suggestions to different parts of the garden. A sketchof an alternative proposal is included as a smaller, faster and cheaper version of the main design proposal.

    Kan växter lindra klimakteriebesvär?: Behandling av vasomotoriska symptom med hjälp av örtmedicin2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study was to investigate the use of herbal medicine for vasomotor symptoms during menopause. The questions posed were which herbs that were used, what parts of the herbs that were used, and how the plant parts were prepared and utilized. The last question covered how much the plants alleviated the vasomotor symptoms.

    A review of the scientific literature was carried out. In the articles, 20 herbs and plants were used, but only five of them were said to relieve the vasomotor symptoms. The five plants were Actaea racemosa, Angelica sinensis, Ginkgo biloba, Glycine sp. and Pimpinella anisum.  The most commonly used parts of the herbs were the roots, often through extracts that were processed in order to increase the concentration and to transform the plant parts into powder. The powder was then for the most part transformed to tablets and capsules. Sometimes, information was missing, such as the scientific names of the plants, what parts of the plants that were used and how the herbs were prepared and utilized.

    On average, the herbs alleviated the vasomotor symptoms by 60 %. Most of the herbs appeared to relieve mild symptoms more than they alleviated strong symptoms. An exception was P. anisum, which decreased both the amount of and the strength of the flushes by 74 %.

    This literature study shows that there are plants that influence the vasomotor symptoms in a positive direction. At the same time, it shows that the information in the articles is sometimes incomplete and that the scientists do not always study if the herbs can give side effects.

    Herbal medicine could be an alternative for women who, for different reasons, cannot or do not want to take synthetic hormones or other pharmacological medicines. However, in order to make herbal medicine part of the treatment offered by public health care, longitudinal studies that also investigate possible side effects or risks are needed for securing the effect of the herbs on the human body.

    Tångodlad potatis- nyttigt eller skadligt?2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The nutrition bound in macroalgae, also known as seaweed, contains high amounts of all the nutrients, micronutrients, vitamins and plant hormones, necessary for plants, animals and humans. Totally for free it is floating in the oceans around the world and has been harvested and used by people for thousands of years. A problem that has arisen in the wake of Industrialism during the past 200 years is that human beings spread non-desirable substancesto air, water and soil, for example heavy metals. Macroalgae accumulate the heavy metals, which may become a problem if we want to eat seaweed or use it to grow plants in.  In a growth trial using macroalgal compost made from Fucus radicans collected from the Baltic Sea, the uptake heavy metals in the edible tubers of potatoes of the cultivar ‘Cherie’ was investigated. The following heavy metals were analyzed: lead(Pb), cadmium (Cd), mercury (Hg), arsenic (As) and copper (Cu). There were no differences in the uptake of heavy metal between potatoes grown in macroalgal compost and soil, but the potato tubers from both cultivations contained concentrations of Cd and As higher than those normally found in Swedish potatoes. The concentrations are, however, much lower than the limits set by EFSA. The macroalgal compost and the soil used in the experiment were also analyzed for heavy metal content. The Cd concentration in the compost exceeded the limit for Swedish compost. However, the high levels of Cd in the compost were not reflected in the Cd content of the potato tubers. Soil conductivity and pH values were also investigated. The high conductivityof the macroalgal compost was probably due to insufficient rinsing of the macroalgae, and thus it was not ideal for use in crop cultivation. In spite of this, the crop yield was good. In conclusion, macroalgal compost can be recommended as a cultivation substrate for potatoes.

    Effects of plant competition and herbivore density on the development of the turnip root fly (Delia floralis) in an intercropping system2009In: Arthropod-plant interactions, ISSN 1872-8855, Vol. 3, 55-62 p.Article in journal (Refereed)
    Abstract [en]

    In this study, interactive effects of plant competition and herbivory on plant quality and herbivore development were examined in a greenhouse experiment where cabbage plants [Brassica oleracea L. var. capitata (Brassicaceae)] were intercropped with red clover [Trifolium pratense L. (Fabaceae)]. Cabbages were grown with two red clover densities and attack rates by the root feeding herbivore the turnip root fly, Delia floralis Fall. (Diptera: Anthomyiidae). Above ground and below ground cabbage biomass was reduced through intercropping and larval damage. Intercropping also resulted in lower nitrogen and higher carbon root levels compared with levels in the roots of monocultured cabbage. Furthermore, both root nitrogen and carbon levels increased with herbivory. Root neutral detergent fibre (NDF) and lignin content increased in response to both increased plant competition and higher egg densities. For lignin, an interaction effect was observed in the form of elevated levels in intercropped plants subjected to larval damage, while levels in roots of monocultured cabbage remained unchanged. The quality changes brought about by clover competition affected D. floralis development negatively, which resulted in reduced pupal weight. In addition, increased egg density also decreased larval growth. The effects on the development of D. floralis in relation to host plant quality are discussed.

    Biokol i stadsträdens växtbäddar: med fokus på Stockholm stad2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The ground is an important factor to consider in today's tough climate for our urban trees. Especially for the trees that shall live in the most vulnerable parts of the city, such as the square, along heavily trafficked roads or surrounded by only paved surfaces. One solution is structured soils which is used in many cities in Sweden but also in other countries. An interesting new development of structured soils where AMA-soil has been replaced with biochar is now being tested in a project in Stockholm. The focus in this paper will therefore be on how biochar is used practically in the tree plant beds and the effects this has on the trees' development.

     

    The purpose of this paper is to get an insight on how biochar in urban tree plant beds are used with examples from Stockholm Biochar Project. And also to examine the parameters used to measure the effect biochar have on tree growth, and to assess the impact of biochar has on the trees.

     

    The work of this paper was carried out as an interview study and was then also combined with research in scientific books and articles. The interviewee is active in the area and works as a tree specialist at the traffic office,Stockholm city and complicit in Stockholm Biochar Project. Researched have been done in various databases where the keywords biokol, biochar, terra preta, urban city trees and tree inventory have been used.

     

    The construction of the plant bed with biochar in Stockholm city has proved to be similar to the old model, but it differs in that the AMA-soil has been exchanged for biochar and also in that the dimensions of the macadam instructured soil is changed.

     

    The parameters used in the Stockholm city to measure tree growth are stem circumference. But there are also other parameters that could be used to measure growth and these could also be applied to assess effect of the biochar on the tree.

     

    In a comparison of tree growth, where tree of the same species had grown in similar conditions but in three different types of plant beds, the results showed that the trees planted in biochar did not have the best growth.

    Byta lind mot lind: En studie om trädbyten vid historiska anläggningar2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this paper is to examine how a tree replacement is carried out in a place that is protected as a cultural heritage. The places described are the Baroque garden in Uppsala Botanical Gardens and the baroque garden in the palace garden at Drottningholm. Both gardens are owned by the state and managed by the National Property Board. The National Heritage Board has overall responsibility that the facilities are not distorted. The Botanical Garden in Uppsala belongs to Uppsala University and is managed by the University. The gardens have a high historical value that make them worthy of protection. Because of this there are restrictions and regulations that dictate how the locations should be maintained and administered. The thesis is based on interviews with the project manager for both of the tree-replacements and the garden Director and 1st gardener at the Botanical Garden in Uppsala. The old lime trees at Drottningholm were planted in the late 1600s and early 1700s and was largely dutch lime, Tilia x europaea 'Pallida', imported from Holland. The old lime trees in the botanical garden was planted in the 1970s, when the garden was restored under the direction of Walter Bauer. The tree replacement at Drottningholm was conducted between 1997–2011 in five stages and the restoration in the Botanical Garden is carried out in autumn 2016 and is expected to be completed in June 2017. Both the construction work and a five-year warranty maintenance is performed under contract. The paper describes what influences the choice of the trees at the facilities. There have been studies to determine the species and varieties of the original lime trees in the avenues at Drottningholm. The new lime trees planted there and those that will be planted in the spring of 2017 in the Botanical Garden, are of the same type as the original lime trees at Drottningholm. A large number of measures have been carried out at the installation and maintenance of the trees to ensure that they establish themselves properly and develop well.

    Hälsoparken Fjärran Höjder i Gävle: Sveriges mest uthålliga och integrativmedicinska hälsoanläggning : rapport avseende: förstudie av integrativ hälsomottagning vid Fjärran Höjder : ett projekt finansierat av Gävle Kommun och Region Gävleborg2009Report (Other (popular science, discussion, etc.))
    Abstract [sv]

    Projektet ”Förstudie av integrativ hälsomottagning vid Fjärran Höjder” har genomförts under hösten 2008. Arbetet har varit inriktat på att följa och genomföra den projektbeskrivning som gavs i samband med ansökan om medel. Till stöd i arbetet har projektledaren haft Arbetsgruppen för en integrativ hälsomottagning vid Fjärran Höjder, vilken sammanträtt fyra gånger under projekttiden. Flera av medlemmarna i arbetsgruppen har också deltagit i studieresorna och föreläsningsserien som anordnats. I syfte att undersöka förutsättningarna för en etablering av hälsomottagningen har en attitydundersökning genomförts bland ett antal utvalda vårdtagare och vårdgivare, politiker, anställda och arbetsgivare, samt besökare vid Fjärran Höjder. Undersökningen visar i korthet att det finns ett stöd för anläggandet av en hälsopark vid Fjärran Höjder. De studieresor och den föreläsningsserie med avslutande dialogmöte som genomförts, har syftat till att förankra idén hos de hälsoaktörer som kan tänkas bli involverade i projektet framöver. Arbetet i arbetsgruppen har mycket handlat om att arbeta fram en projektidé, ett program eller en projektplan för den föreslagna integrativa hälsomottagningen. En viktig del i en sådan plan har varit att sätta in mottagningen i ett större sammanhang, det vi nu vill kalla Hälsoparken Fjärran Höjder. Hälsomottagningen skulle då ingå i en större helhet, en miljö vars samtliga delar syftar till att främja hälsan hos parkens besökare. Visioner och mål för hälsoparken har arbetats fram, liksom ett preliminärt förslag till utformning av hälsoparken och verksamhet där vid. I fortsättningen av projektet avses att söka medel från Osherstiftelsen och i det fall projektet får fortsatt stöd från Gävle Kommun och Region Gävleborg även EU-medel, eftersom det krävs egenfinansiering vid sådana ansökningar. Förslag till hur projektet kan vidareutvecklas lämnas i rapportens avslutande del.

    Odling i sand: En undersökning av markfysikaliska egenskaper hos sandjordar och om anläggning av odlingsbäddar2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med examensarbetet är att försöka förklara de markfysikaliska egenskaperna hos en sandjord och hur det med hjälp av olika kornstorlek är möjligt att uppnå dessa egenskaper i en odlingsbädd. Sandjordar kan anses som problematiska då de har svårare att behålla fukten i jorden och dessutom är näringsfattiga. Detta gäller såväl artificiella som naturliga sandjordar. Vattnet kan beroende på kornstorlek och tillförsel av mull ha lättare eller svårare att förflytta sig i marken. Detta kan vara avgörande för hur en växt överlever och trivs i en sådan miljö. Den värmehållande förmågan varierar på grund av sandjordens kornstorlek och inblandning av mull. En sandbädd blir varm tidigare på våren än en bädd av mull och därför kan odlingssäsongen förlängas. En planta som är härdig t ex, till zon II, har om den står i sandjord större chans att klara vinterhalvåret i en högre belägen zon, än om den är planterad i mulljord men jordens fukthalt har också en avgörande betydelse. Det är viktigt att sandjorden har en bra sammansättning – är det för stor andel mycket små partiklar dräneras inte överflödigt vatten bort och vattnet blir stående i sandbädden - vilket medför ökad risk att plantan fryser under vintern. Syftet med uppsatsen har också varit att undersöka hur en odlingsbädd av sandjord kan anläggas. Under uppbyggnaden av stenpartiet har jag kunnat se med vilka medel det går att ändra förutsättningarna i en sandbädd så att växter som inte är helt härdiga i vårt klimat eller som kräver speciella miljöer ändå kan överleva och trivas i vår del av världen. Studien av de markfysikaliska egenskaperna hos sandjordar har hjälpt till att förklara hur de sandbäddar som anlagts fungerar. Under arbetets gång har det även framkommit att de metoder som studerats inte kan användas överallt och att det finns flera problem med sandjordar. De är näringsfattiga och när näring sprids ut kan den på grund av sandjordens dåliga förmåga att behålla näring, orsaka näringsläckage i närliggande vattendrag.

    Pilodling till användning inom trädgård och hantverk: med tonvikt på zon 52013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med det här examensarbetet är att undersöka hur pil, eller mer specifikt, sorter inom släktet Salix sp. odlas för användning inom hantverk och trädgård. Bland dessa sorter kan nämnas korgvide (Salix viminalis). Denna typ av odling är småskalig och syftet är att få material till flätning av exempelvis korgar eller grövre arbeten som hägn och staket i trädgård. Materialet som används är vanligen ettåriga skott av odlade pilsorter som skördas när plantan är i vintervila. Därefter torkas skotten i ca 6 månader för att sedan blötläggas innan flätningen påbörjas. Blötläggningen gör pilskotten mjuka och böjliga. Pil kan även användas färsk till att skapa levande hägn genom att pilskott sticks ner i jorden och får rota sig.

     

    I detta arbete finns information om hur man kan gå tillväga för att anlägga och sköta en pilodling samt vilka markförhållanden och skötselmetoder som krävs. Fakta har samlats in genom att studera litteratur inom området, studiebesök samt mailkontakt med pilodlare. Här finns även en sammanställning av pilsorter som är härdiga att odla i zon 5.

     

    Även odling av Salix sp. för användning till biobränsle, s.k. energiskog har studerats. Anledningen till detta är att dessa odlingar, som även kallas salixodlingar, till stor del består av ovan nämnda sort korgvide (S. Viminalis). Då det har forskats mycket inom detta område har informationen varit av nytta både vad det gäller odlingsbetingelser och härdighet för Salix sp.

     

    Slutsatsen är att tillräckligt mycket information har hittats för att svara på syfte och frågeställningar. Fakta från energiskogsodlingen har inom vissa områden gett vägledning om hur skötsel av en småskalig odling kan förbättras. Även kommunikationen med verksamma pilodlare har lyft fram förslag till förbättringar.

    Corporate Garden: att kommunicera varumärke eller verksamhetsområde genom den yttre miljön2012Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Företag och organisationer arbetar mycket med att förstärka sin position på marknaden, att leva upp till sin image och stärka sin identitet. En viktig del i arbetet handlar om att bygga ett starkt varumärke utifrån verksamhetens kärnvärden som når ut till kunderna. Det gäller att vara tydlig i sin kommunikation. Ofta kan man se en röd tråd genom ett företags grafiska profil, hur lokalerna är utformade och hur man marknadsför sig. Att inomhusmiljön speglar företagets profil och värden är lika vanligt som att ha en tydlig grafisk profil och en logotype på sitt visitkort. Däremot har de flesta företag inte någon tydlig koppling mellan miljön inomhus och den yttre miljön. Ofta är det bara företagsnamnet och loggan på husfasaden som vittnar om att företaget huserar där. Genom Corporate garden kan företag som en del i en genomtänkt företagsprofilering kommunicera sin verksamhet. Syftet med mitt examensarbete är att undersöka hur ett kommunalt tjänsteföretag kan kommunicera sitt varumärke eller sitt verksamhetsområde genom den yttre miljön.  Jag har använt mig av Sandviken Energi som studieobjekt. Till dem har jag gjort ett gestaltningsförslag, en Corporate Garden, som en del i examensarbetet. Min grundtanke har varit att kombinera funktion med kommunikation där jag använt mig av material från verksamheten som delvis kommunicerar vad företaget arbetar med. Genom att göra en processbeskrivning kommer arbetet kunna följas löpande fram till ett slutförslag. Processen omfattar informationsinsamling, analys av platsen, skissfas, skissmetod, problemlösning kring bristen på parkeringsplatser, resonemang kring idéer samt ett slutförslag som visar en utemiljö där innehållet speglar företaget och dess verksamhet.

    Mating dynamics of Scots pine in isolation tents2016In: Tree Genetics & Genomes, ISSN 1614-2942, E-ISSN 1614-2950, Vol. 12, no 6, 112Article in journal (Refereed)
    Abstract [en]

    Seed orchards are forest tree production populations for supplying the forest industry with consistent and abundant seed crops of superior genetic quality. However, genetic quality can be severely affected by non-random mating among parents and the occurrence of background pollination. This study analyzed mating structure and background pollination in six large isolation tents established in a clonal Scots pine seed orchard in northern Sweden. The isolation tents were intended to form a physical barrier against background pollen and induce earlier flowering relative to the surrounding trees. We scored flowering phenology inside and outside the tents and tracked airborne pollen density inside and outside the seed orchard in three consecutive pollination seasons. We genotyped 5683 offspring collected from the tents and open controls using nine microsatellite loci, and assigned paternity using simple exclusion method. We found that tent trees shed pollen and exhibited maximum female receptivity approximately 1 week earlier than trees in open control. The majority of matings in tents (78.3 %) occurred at distances within two trees apart (about 5 m). Self-fertilization was relatively high (average 21.8 %) in tents without supplemental pollination (SP), but it was substantially reduced in tents with SP (average 7.7 %). Pollen contamination was low in open controls (4.8-7.1 %), and all tents remained entirely free of foreign pollen. Our study demonstrates that tent isolation is effective in blocking pollen immigration and in manipulating flowering phenology. When complimented with supplemental pollination, it could become a useful seed orchard management practice to optimize the gain and diversity of seed orchard crops.

    outcome has been and how the users of the green environment, think about the result. In

    the process there has been a strong concern of involving the residents and others using

    the area. I also discuss the results concerning plantation problems, which I can see may

    influence the site identity and the quality of green areas, which in turn also can affects

    the residents relationship to it. The result also suggests that there still are possibilities

    for improvements in the dialogue and the participation of the residents of the area under

    the concept that’s been named "Dynamic habitat". The outdoor green environment can

    also further provide life quality for the inhabitants and other users, while it hopefully at

    the same time, promote the knowledge of ecosystem services.

    Fine-scale environmental variation contributes to introgression in a three-species spruce hybrid complex2015In: Tree Genetics & Genomes, ISSN 1614-2942, Vol. 11, no 1, 817Article in journal (Refereed)
    Abstract [en]

    Hybridization is common for many forest trees, where weak barriers to reproduction obscure species boundaries. We characterized the genomic structure of Picea populations comprising three species spanning two well-known contact zones, the Picea sitchensisxPicea glauca and the P. engelmanniixP. glauca hybrid zones, using a set of 71 candidate-gene single nucleotide polymorphisms. The genetic structure of populations suggests a complex genomic architecture shaped by interspecific gene flow and strong environmental selection, with increased genetic diversity in hybrids. The presence of admixture among all three species suggests that three-way hybrids with mixed ancestry occur where species ranges overlap in transitional environments. Significant clinal variation and associations with climatic variables (including continentality, temperature, and precipitation) differ between hybrid zones, indicating that individual species and their hybrids are adapted to distinct environmental niches. Allele-environmental association analysis revealed that most of the candidate genes with evidence of selection were unique to either the Sitkaxwhite or the Engelmannxwhite hybrid zones, with few shared between these zones. Management of these widespread and diverse gene pools will be best served through development of climate-based seed transfer, with recommended seed sources informed by a combination of genetic and climatic information for future climates.

    Funktion och vegetation för  biofilter i kallt klimat: Med fokus på Gävle2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Stormwater often brings the city's pollutions whit it and therefore there might be a need for treatment of the water, to protect the recipient. Bioretention systems are systems for stormwater retention and treatment, that uses the chemical, biological and physical properties inherent to the soil, microbes and plants for pollutant removal. Bioretention systems are typically constructed as an infiltration bed with vegetation upon it. The city of Gävle usually leads it’s stormwater directly into small waters, it is only a very small proportion, of stormwater that is led to the sewage treatment plant. That there is an interest in bioretention systems in Gävle has emerged through interviews with people who are active within the green sector in Gävle.

    This work aims to provide an insight into how bioretention systems operates under Swedish climate conditions and give suggestions for plants that could fit in a bioretention system if it were placed in the climate of Gävle. The issues this master thesis will try to answer are:

    •  How does bioretention systems operate in a cold climate?
    •  Which plants would be suitable for a bioretention system in Gävle?

    This work was conducted as a literature study in which facts have been searched in different databases, with keywords like biofilters, bioretention and cold climate. For the lists of plants that are included in the work, the facts have been searched in, inter alia, the plant database Plantarum and garden literature. A small interview study has also been implemented in the work and the people who have been chosen for the interviews are active in the green sector in Gävle and work at companies that have a major impact on the city design

    In areas with cold climates, storm water management with bioretention systems are facing some difficulties in the winter, such as reduced biological activity, temporal freezing and road salt. Studies on bioretention systems efficiency and treatment capacity in cold climates have shown that the bioretention systems works well even in cold conditions.

    The vegetation in a bioretention system have multiple functions and effects, among other things, they contribute to the removal of metals, allowing sedimentation and contribute to the development of the biofilm. When choosing plants for bioretention system you should look at plants that tolerate dry to normal ground conditions. It is also good to have a mixture of fast-growing and slow-growing species and combine plants with shallow and deep root system. When choosing plants for a city like Gävle resistance is an important factor to take into consideration, it is also important with healthy plant material. Based on this, suggestions of plants have been compiled in various plant lists.

    Research results on bioretention systems performance and treatment capacity in cold conditions indicate that the use of biofilters for stormwater treatment is a working system also for areas with cold climates. The use of bioretention systems appears to be increasing in the future and as it is a rather new system in Sweden there is a need to spread information and awareness about the systems functions and values.

    Visby vallgravar: del av ett rikt kulturarv eller bara en kuliss?2014Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    The cultural heritage management’s handling of the green environments has long been inadequate, which Visby moats are exemplifying. The park area that extends along the city wall from north to south today provide a rather natural impression de­spite in the late 1800s undergoing extensive plantings and thus are highly deliberately formed. This has resulted in a poor under­standing of why the moats look like they do. When Visby was included in the UNESCO World Heritage list in 1995 the moats were pointed out as a buffer zone. In a contrasting way the municipal authorities have, in recent years, been developing plans for exploitation within and close to the moat area.

    The research has, with Visby as an example, aimed to show how green cultural environments might be interpreted in different ways when we choose to ascribe to them specific layers of time and thus ignore the others. Secondly, the aim has been to look into how the buffer zone concept is applied in municipal planning and in this way raise the case to an international perspective.

    The research has shown that the work of Planteringsgillet largely shaped today's moat area. Meanwhile, mismanagement through history along with recent years' “Middle Ageifying" have led to a focus directed away from recent history and rather concentrated on the Middle Ages. In relation to the medieval world heritage city and the city walls the moats have come more to represent a coulisse than a part of cultural heritage. The buffer zone concept has shown to face problems in the implementation in national law which is one of the reasons for a passive approach to the area concerning ​​the World Heritage issue. Paradoxical contradictions in the form of exploitation plans and a desire to expand and clarify the World Heritage Site is one of the results that have demonstrated a need to increase knowledge and a clearer way to secure the viability of the world heritage and the moats.

    Abstract [en]

    Considering urban trees importance for humans in both environmental and health aspects, this study aimed to explore appropriate urban tree species and varieties with a focus on prevention for current and future epidemics. The basis for this study is Gävle. It is of interest to see what suited a little further north in Sweden, zone 4. This literature survey is based on scientific articles, other literary writings and conversations references with industry expertise and these issues have been the focus. * How does the city tree population looks in Gävle today? * How to choose the new urban trees based on current and future disease epidemics? * What park trees and street trees are suitable for planting in Gävle in order to increase diversity? Gävle has previously, like many other municipalities, planted trees prevailing on trends. This has resulted in an over-representation of the tree genera Tilia, Sorbus and Acer. Invasive disease similar to Ash dieback and Dutch elm disease can knock out large parts of the urban tree population caused by monoculture. Diversity is of great importance in this regard. City tree population should not exceed more than 10% of a species, 20% of a family or more than 30% of a family. It has been a two folded guidelines in the selection of urban trees:

    * Get a better understanding of the prevailing conditions in the urban environment and to enhance the experience on which species thrive in these conditions. * Expand the existing tree population by gathering more knowledge and dare to try new and / or untested species. Recommendations of street trees and park trees in both zone 3 and zone 4 are presented in the report. Interestingly, it emerged both species / varieties that occur in nurseries today but also tree species / varieties that have not yet been introduced.

    Hållbara växtbäddar för perenner i offentliga miljöer2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med detta arbete är att ta reda på vilka problem det finns i perennplanteringarna i offentliga miljöer samt hur man kan förebygga problemen och hur man bygger upp växtbäddar för perenner utifrån ett hållbarhetsperspektiv. Undersökningen genomfördes hösten 2011 och baserades på litteratur som böcker, artiklar, faktablad samt intervjuer. I undersökningen ingick fem angränsande kommuner till Gävle samt tre erkända trädgårdsmästare. Utgångspunkten för valet av trädgårdsmästarna var att de skulle ha erfarenhet av att skapa väl fungerande och hållbara exempel på offentliga perennplanteringar i Sverige.

    Det finns många olika orsaker till att perennrabatterna i våra offentliga miljöer inte ser så attraktiva ut. Oavsett orsak så kan man säga att grundproblemet är bristfällig kunskap och eventuellt brist i kommunikationsleden från ”idé till planta” när det gäller de offentliga planteringarna.

    Det är många delar som är viktiga i en växtbädd för att perenner, träd och buskar ska kunna etablera sig och utveckla sin prakt år efter år. En av dessa komponenter är en bra jord. Det är viktigt att man väljer en rotogräsfri jord utifrån växtvalet redan från början. Ett av problemen i kommunerna var att fel sorts jord hade använts från början. Trots att alla påstod att de använde sig enbart av rotogräsfri jord i dagsläget så hade de problem med ogräs. Två orsaker till detta kan vara att man väljer fel växter och att skötseln inte fungerar, vilket resulterar i att ogräset tar över.

    Den perfekta växtbädden, finns den? Eftersom det är naturen vi arbetar med är det svårt att uppnå det ultimata resultatet, men vi kan göra det bästa utifrån förutsättningarna som finns med alla de delar som ingår i en växtbädd.

    Odling av vedartade växter i kärvt klimat: En studie om zonkartans användning i Norr- och Västerbottens län2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The hardiness of a plant is often strongly associated with the recommendations on the climate zone map. However, it is not only the climate zone recommendation that determines whether a plant is cold hardy enough to survive and thrive at a certain location. 

    By sending a questionnaire to local growers in northernmost Sweden I wanted to investigate how the climate zone map is used and how well it works in the northern part of Sweden. Most growers were positive to the recommendations in the map. However, they pointed out that the climate zone map does not take into account the genetic heritage, the local microclimate and the requirements of the location on which the plant is supposed to grow, which are all very important. Growers mentioned that more information about how to create a good micro climate for a certain plant in a certain zone would be very useful.

    From the questionnaire I have put together a list of plants that growers in northern Sweden have grown outside the recommendation from the climate zone map. And by using information from the growers together with information from my literature study I have created a suggestion on an updated climate zone map to see if it is possible to raise knowledge and increase plant selection in northernmost Sweden.

    Matematiska mönster i naturen och hur de kan göra bostadsgården mer hälsofrämjande: En teori av en trädgårdsmästare2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    My theory is that one of the explanations for the nature's positive impact on us is that nature is easy to read when we decode our surroundings. In nature there are mathematical patterns that recur and repeat themselves like the Fibonacci numbers, Golden Ratio, Phyllotaxis spiral and especially fractals. These patterns help us to record and take in information from what we see in our surroundings to understand it but also to determine if there is something scary or if we are in a safe place.

     

    In research where they investigated the subjects’ eye movements it was found that we automatically attach our gaze at pattern of the fractal dimension 1.3 – 1.5. Further experiments showed that the test subjects where the most relaxed when they saw pictures with a dimension value within that range. I found additional support for plant health effects in a report from an experiment in which test subjects touched different materials blindfolded. The research team wanted to measure both psychological and physical reactions. The test subjects were instructed to value their experiences based on 10 pairs of word opposites and additionally their oxygen saturation in the blood and the cerebral blood flow were monitored. The psychological part of the trail gave a neutral result, but the physical measurements indicated that the subjects were stressed by touching metal and were more relaxed when they touched living plant material (a fresh leaf). The conclusion was that physical contact with plant material can have a calming effect, even though the subject does not know it is plant material it touches.

     

    By bringing in these patterns to apartment house courtyards they would become more health promoting for the urban human. Since the herbal layer is underrepresented in these areas today, I have chosen to focus on perennials that would bring in the fractal and mathematical patterns in this environment.

    Abstract [en]

    The purpose of this report was to put together facts regarding how the measures before and after tree transplanting can affect the establishment of the tree. The report also dealt with the impact that root pruning might have on trees and how regeneration of roots can be promoted. The report answers questions concerning how tree transplanting affects a tree and how tree species, locality and previous measures can influence the effect of a tree transplanting. The reports also answers a question concerning which measures could be performed, before and after tree transplanting, to improve the tree’s establishment in it’s new locality. The last question that this report answers is what impact root pruning has on the tree and how regeneration of fine roots can be favoured. The report is written as a traditional academic report and is based on literature that was collected from scientific articles, books and encyclopedias. A tree loses a large amount, approximately 90 percent, of its root system during the tree transplanting. This causes stress symptoms in the tree. A tree, sown and grown in nature, that has never been root pruned will lose even larger amounts of its root system when it’s transplanted. It’s important to do investigations before tree transplanting. Investigations should be done before tree transplanting to determine what kind of tree, nursery-grown or grown in nature, and what species is about to be transplanted. Both of these aspects may have an influence on how successful the transplanting is. Root pruning can make the root system more compact which reduces root loss during transplanting. Root pruning also increases the amount of fine roots in the root ball which is beneficent during establishment and also reduces water stress. The high amount of root loss causes an imbalance between crown and roots. The crown is often reduced to correct this imbalance and in this report it was proven that a moderate crown reduction is beneficial for the tree. The tree must overcome the stress symptoms to be able to survive and to establish itself. Trees need good vitality to be able to regenerate roots, shoots and branches. Irrigation plays an important part in the establishment and the survival of the tree. Mulch can promote regeneration of fine roots and contribute to an improved establishment. The conclusion of the report is that both preparatory measures and after care has an impact on the establishment and on how successful the transplanting of a tree will be. A correctly executed root pruning and a moderate crown pruning (10 to 30 percentage of the crown) should be carried out. Trees should be transplanted during their dormant season and trees, that are going to be transplanted, should have high vitality. Regeneration of roots is promoted by having good soil moisture, warm soil, even watering and applying mulch.

    Ekologiskt hållbar parkförvaltning2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Ekologisk hållbarhet handlar om att se till att ekosystemen fungerar och inte utarmas. Det är viktigt att sträva efter på alla plan i samhället, även genom ekologiskt hållbarskötsel inom parkförvaltning. Ekologiskt hållbar skötsel innebär att ha ett kretsloppstänkande. Att skapa förutsättningar för biologisk mångfald. Det innebär även att använda miljövänliga maskiner, produkter och arbetsmetoder. Det är bättre för arbetsmiljön och kostnadseffektivt på sikt. I tidigare studier har det framkommit att koloniträdgårdsamatörer ofta har större kunskaper om ekologiska funktioner och att det återfanns en högre biologisk mångfald i deras parker än hos park- och kyrkogårdsförvaltare.

    Syftet med denna studie är framför allt att försöka förstå vilken betydelse ekologisk hållbarhet har för förvaltningen av offentliga parker. Syftet är även att ta reda på hur ekologiskt hållbara skötselmetoder tillämpas i offentliga parker. Studien ska ta reda på vad företeelsen och begreppet innebär för parkförvaltare. Den ska också undersöka hur förvaltare sköter parker och om de har en ekologiskt hållbar skötselinriktning. Studien bygger på fyra intervjuer av parkförvaltare.

    Resultat visar att parkförvaltare ser positivt på att använda ekologiskt hållbara metoder. Det är av olika innebörd för förvaltarna beroende på kompetensnivå. Många av förvaltningarna har en ekologisk skötselinriktning eller tillämpar ekologiskt hållbara metoder på ett eller annat sätt. Resultat visar även att det främst är ekonomi och medarbetarnas kompetens som påverkar om förvaltningen har en ekologiskt hållbar skötselinriktning. Förhoppningsvis kan studien uppmuntra parkförvaltare att ta till fler ekologiskt hållbara skötselmetoder i deras parker - för en bättre arbetsmiljö och högre biologisk mångfald som en följd.

    Abstract [en]

    Abstract

    The customer demand for ecological products has increased in recent years, within the garden industry this mainly concerns herbs and other edible plants. The organic trend is increasing and more people are aware of the environment and want to take responsibility for it through their purchases for their garden as well.

    In this essay the aim is to investigate customer demand and the possibility of selling organic

    perennial plants in eight garden centres on the Åland islands and in Gävle/Sandviken. I include two garden centres with an organic profile to get a wider point of view. I investigate the global market for organic perennials and look further into existing certification standards on the Swedish market today.

    The methods I have been using are interviews and a literature study.

    The study shows that the experienced demand for organic perennials is small in both of my

    investigated groups. The biggest motivation for starting to sell organic perennials would be to find a supplier of these plants and that more customer would ask for them. The certification systems on the Swedish market today do not concern specifically organic perennials; there is a lack of rules of conduct. In USA the demand for organic perennials has increased in recent years. Several nurseries with an organic profile have opened and programs for guidance of organic growers have been founded. In Germany the production of organic perennials is small and organic certification is lacking. In both countries further research on the market for organic perennials is suggested.

    Gräsmattans "vara eller icke vara": En undersökning av den traditionella gräsmattans moderna dilemma2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The traditional lawn is believed to be facing a dilemma. On one hand, it is valuable for people because of its esthetical and functional values. On the other hand, the lawn is perceived as a monoculture without biological diversity that hinders the domestic landscape’s flora and fauna. In this graduation-thesis, the private and public lawn’s dilemma of “to be or not to be”, is examined from these two different perspectives. The following questions were formulated to answer this: 1) How did the lawn come into existence and what values has it had for people throughout the years? 2) What esthetical and functional values do public and private lawns have for people today? 3) Is it possible to identify a tendency that the lawn is on its way out?

     

    A survey was used as the primary method to answer these questions, in addition to literature-studies. The survey was published between October 24 and 28, 2014, in the Facebook-group “KÖKSTRÄDGÅRDEN – Le Potager – The Kitchen Garden”. 158 respondents completed the entire survey.

     

    This study shows that the lawn’s historical values have foremost been to function as expressions of power, as areas for sports, playing and recreation and as an esthetical factor. These values remain important today but additionally a tendency of people valuing a well-kept and environmentally-friendly lawn can be identified. It was not possible to identify tendencies that the lawn is on its way out. It was, however, possible to conclude that a redefinition of the lawn is possibly about to begin.

    Abstract [en]

    This study is dealing with how existing parks in urban areas can fill a bigger role for bumblebees then they are today. My questions concern: lack of food for bumblebees in parks, lack of opportunities to find places to live and to hibernate and actions how to mitigate this. The results of this study show that existing parks can have a bigger positive impact on the biodiversity in urban areas. If bumblebees can’t find places to live or hibernate or find food, the risk is then that their populations will continue to decline which will have a strongly negative effect on us humans because we are depending on pollinators. With the right knowledge and measures we can make it easier for bumblebees to live in urban areas. To facilitate for biodiversity in the planning of parks means that we will create oases which both humans, birds and insects can benefit from.

    Förslag till tidstypisk efterbildning och restaurering av en trädgård i Söderhamn: Byggd på studier om egnahemträdgårdar och trädgårdsmästaren Rudolf Abelin2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose behind this thesis is to create a design proposal for how a present day garden created at the early 1900 can be recreated to its original design. In order to do so, the style of the garden specified to this era must be defined along with an inventory of the plants. The garden used for this specific assignment is located in Söderhamn and the property is called ‘Killingen’. The main house as well as the garden was created in the beginning of 1900. Killingen´s garden is classed as a ‘own-home garden’. These kinds of gardens were influenced by the ‘own-home movement’ which started in the 1900-century. The main purpose of this movement was to help low income families finding a better and own home with a garden. It was also there in aid of preventing the mass emigration around that period. Around this time, a very influential gardener, Rudolf Abelin, played a key role for the own-home garden’s development through his writing and widespread knowledge. For him the garden was part of the society development which also was affected and influenced by his ideas and involvement. The methods used in this thesis are mainly literature studies but also includes observations of current gardens and conversations with relevant people. Thanks to the current owner’s very ambitious and existing list of plants of the garden, it’s actually been possible to rely on literature in order to propose new plants as well as suggesting which plants were not part of the own-home movement and could therefore be removed as they are not part of the same style.

    Abstract [sv]

    Allén förklaras som en väg eller gata med planterade träd på båda sidor, vanligen i enkla rader men även flerdubbla led. Allén är en anläggning som innehåller minst 7 träd.

    • •Alléerna anlades förr ofta för att genom hamling ge bonden djurfoder och bränsle
    • •Alléerna anlades för att hindra jordflykt på skånska slätten.
    • •Alléerna anlades för att ge en park eller ett slott en gedigen och praktfull utsmyckning som i sin tur visade makt och rikedom på 1600-1700-talet.
    • •Alléerna anlades för att rama in vägen och ge resande en linje att hålla sig till vid dålig sikt men också att ge skugga och återhämtning för resande. Det kunde vara i en hälsopark på 1800-talet eller då man färdades på landsvägen med häst och vagn.
    • •Alléerna anlades som en tydlig in/utfartslinje till en stad.

     

    Det har tydligt framkommit i litteraturen att allén delas upp i landsvägsalléer och parkalléer. Landsvägsallén har oftast inte träd med sammanvuxna kronor. De kantar istället in en väg på båda sidor eller ena sidan. Landsvägsallén kom till i ett syfte att markera vägen vid dålig sikt samt binda jorden kring öppna odlingsytor. Landsvägsalléerna bestod ofta av olika trädslag. Och det togs hänsyn till hur väl det gick att plantera på den platsen. Bönderna använde landsvägsalléns grenar till djurfoder och bränsle.

    Parkalléerna är de som i första hand blev ett blickfång, en estetisk del i parken som från början manifesterade makt och rikedom. Allén skulle vara enhetlig och formklippt. Trädens kronor skulle vara sammanvuxna och helst vara i samma höjd och det innebar att samma trädslag helst användes i parkalléerna.

    Alléer finns att se i hela Sverige, både i stadsmiljö och på landsbygd samt vid stora gods, gårdar och slott. Nutida alléer vårdas i samarbete med länsstyrelse och vägverk samt genom stiftelser och projekt. Bevarande sker med bestämmelser och lagar som grund.

    Uppdragsforskning och kunskapsbyggnad runt vård och bevarande av dagens parkalléer finns för slotts- och parkförvaltare i form av vårdprogram som SLU har tagit fram.

    Alléns namn kommer från det franska språket och allén som idé anlände till Sverige genom renässansen intåg till Europa.

    En blomstrande marknad: handelsträdgårdar i Sverige 1900-1950 med fyra fallstudier i Stockholms län2014Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The main aim of the thesis is to contribute to an increased understanding of the development of the horticulture industry, especially the market gardens in Sweden during the period 1900-1950. Market gardens produced vegetables, flowers, berries, fruits, and annual bedding plants. It was a resource-intensive production on open-field, in hotbeds and greenhouses. Changes of the strategies and competitiveness in the market garden businesses are described and discussed, during a period when the number of companies and imports both increased considerable. Four case studies of market gardens in Stockholm County form the foundation of the thesis. They represent the two most common types of market gardens at this time: sole trader market gardens (often family businesses) and manor gardens (run with the help of employees). Primary source materials consisted of accounting records, business and personal correspondence, diaries and photographs. The collection of such material constituted part of the thesis. Theories and concepts are taken from economics and entrepreneurship and have been used to visualize, clarify and discuss developments in the case studies. Some of the issues relating to the production and trading of the garden products are resources, strategies, competitiveness, range and flexibility. Some of the topics covered in greater depth is the gardener's knowledge and knowledge acquisition, cultivation techniques, the range of produce, the market gardens localization, trading and marketing of horticultural produce, social, political and economic changes in society that affect horticulture and its operators. During the time period 1900-1950, the demand for garden products increased rapidly and both domestic production and imports of these products increased. During the two world wars imports were rationed, which favored the cultivation within the country. At the beginning of the century market gardens were often established in or nearby cities, where the necessary resources were available that contributed to their competitiveness compared to others who grew and sold garden produce. The hot beds demanded a great deal of fresh manure and other waste in the cities, which was a problem, and thus a resource that was easily accessible to the gardeners. Market gardens thus became part of the city´s cycle, using waste to create an important resource for the production of food. More efficient transport, new more robust varieties, better handling after harvesting, suitable packaging and reduced need for labor meant that the significance of place changed. For customers, the producer increasingly became anonymous. Many growers sold their produce to wholesalers, who subsequently sold it to grocery stores or local shops. Wholesalers were interested in uniform produce in a standardized range and demanded other qualities of the produce than customers whom gardeners met at markets did. Gardeners at manor gardens enjoyed a high status at the beginning of the twentieth century. Just over fifty years later, most of the manor gardens had either been leased out or closed down. Times were also hard for many family-run businesses after the Second World War, but it would take another couple of decades before most of these closed down. Originally, a lot of production in manor gardens had been for resident families’ personal demand for utility and ornamental plants. Gardeners were also in charge of the cultivation of more pleasure-focused aspects of gardening that were an important part of the environment and functioned as a demarcation of status for the resident family. As the production of plants for sale increased, the demands on revenue increased. At the same time, some of the old demands lived on; for example, with respect to parkland and other cultural values that should be maintained, and families had specific requests about what should be grown. That meant that certain services and products were demanded regardless of whether these were profitable or not, and that made it more difficult to rationalise the crops to improve competitiveness.

    En handelsträdgård i Stockholms skärgård2012In: Bulletin för trädgårdshistorisk forskning, ISSN 1652-2362, no 25, 17-19 p.Article in journal (Other academic)
    Abstract [sv]

    Trädgårdsmästare Erik Nilsson föddes på Runmarö i Stockholms skärgård 1915. Hans intresse för trädgårdsodling väcktes redan i unga år efter en säsong i trädgårdsmästare Lundqvists handelsträdgård på Runmarö. Han trivdes med arbetet och hans far sa då att ”ska du jobba med sånt så kan du väl odla här hemma”. Så redan som 14-åring, 1929, planterade Erik 200 jordgubbsplantor i föräldrarnas trädgård, följt av ytterligare 1 000 våren därefter! Det finns anteckningsböcker bevarade från de första åren och där skriver han bland annat att jordgubbsodling skulle bli hans specialitet. Jordgubbsodlingen i Stockholms skärgård var omfattande från slutet av 1800-talet, till exempel på Möja och Harö. Bären fraktades in till Stockholm med båt och såldes där på torgen.

    Julita park och trädgård under 1900-talet : Kunskapsunderlag inför arbete med vårdprogram för Julita park och trädgård2015Report (Other academic)
    Abstract [sv]

    Julita gårds siste ägare, Arthur Bäckström, testamenterade gården i sin helhet till Nordiska museet, som tog över den efter Bäckströms död 1941. Hans önskan var att ”Hufvudbyggnaden med flyglar och ekonomibyggnader jemte angränsande område såsom trädgård och park böra så vidt möjligt bibehållas i oförändrat skick för att för kommande slägten gifva en trogen bild, hur en gammal sörmländsk herrgård af betydligare omfång tedde sig under slutet af förra och början af innevarande århundrade.” Sedan slutet av 1980-talet har det funnits en vision av att återskapa delar av Julitas park och trädgård, så långt det är praktiskt och ekonomiskt möjligt, för att besökarna ska få en känsla av hur dessa anläggningar såg ut på 1930-talet, då de var som mest praktfulla.

    I rapporten finns en genomgång av vilka dokument (vårdprogram, inventeringar och liknande), från 1941 och framåt, som behandlar Julitas trädgård och park. Här beskrivs även hur trädgård och park förändrats, område för område, från omkring 1988 och framåt, med utgångspunkt från dokument, intervjuer och fotografier.  Detta faktaunderlag ska ligga till grund för arbetet med en vårdplan för Julitas trädgård och park. Resultatet av dessa genomgångar visar att dokumentationen av park och trädgård varit mycket bristfällig genom åren. Det skriftliga materialet har därför kompletteras med ett rikt bildmaterial, samt med intervjuer av personer som arbetat eller bott på Julita gård sedan 1988 och omkring tjugo år framåt.
