Fire doing nature protection : Vascular plants and vegetation development after prescribed fire in two nature reserves in Småland, Sweden (English)
Abstract [en]

This study has taken place in two nature reserves in the municipality of Uppvidinge in the Kronoberg region in southern Sweden. These have been chosen by the County Administrative Board to be part of a bigger landscape of fire affected nature, and prescribed fire has been implemented in these. The areas are called Ösjöbol and Berga fly and have been burned 2012 and 2013 respectively. Non-burned areas have been inventoried as well. Vascular plants and mineral soil have been inventoried with the Hult-Sernander-Du Rietz scale of five levels.

 

Issues emanate from the County Administrative Board’s goals for prescribed fire: how sticks and herbs were affected, how much soil was uncovered, how the structure and fire favoured species were affected, and how deciduous trees and spruces (Picea abies) were affected.

 

The study shows that the soil increased, as well as the fire favoured species. The structure of species was changed to being more dominated by herbs than sticks. New spruces were not found, and no aspens (Populus tremula) grew on the fire site. Generally, the forest is more open and richer in number of species, but to maintain a continuously dynamic forest, more fires are needed.

Abstract [sv]

Denna studie har utförts i två naturreservat i Uppvidinge kommun i Kronobergs län. Dessa är av Länsstyrelsen utsedda att ingå i ett större landskap av brandpåverkad natur, varför det har genomförts naturvårdsbränning i dem. Områdena heter Ösjöbol och Berga fly och har bränts 2012 respektive 2013. Ej brända kontrollytor har också inventerats. Kärlväxter och blottad jord har inventerats med Hult-Sernander-Du Rietz femgradiga skala. Resultaten har testats för statistisk säkerhet och redovisas i diagram och tabeller.

 

Frågeställningarna utgår från Länsstyrelsens mål för naturvårdsbränning och behandlar: hur ris och örter påverkats, hur mycket blottad jord som förekommer, hur artstrukturen i allmänhet och de brandgynnade arterna i synnerhet har förändrats, samt hur nyetableringen av lövträd och minskningen av gran (Picea abies) fungerat.

 

Studien visar att blottad jord ökat och likaså brandgynnade arter. Artstrukturen har förändrats till mer örtdominerad än risdominerad. Nyetablering av gran förekommer inte, men man har inte lyckats få in asp (Populus tremula) på brandfälten. Över lag har skogen blivit mer öppen och mer artrik, men för en på sikt fortsatt dynamisk skog krävs fler bränningar.
