Abstract [en]

Billstaån is a river in Jämtland, Sweden, affected by small-scale hydropower use from history to present day. As a result, the ecological status in the river is low, despite high potential as habitat for e.g. brown trout. To mitigate some of the main environmental impacts restorative measures are planned in a joint effort by the company Jämtkraft AB, being owner of the existing hydropower facilities, the County Administrative Board of Jämtland and other local stakeholders. The measures include construction of bypass channels to mitigate current migration barriers, deconstruction of an unused dam and planting of freshwater pearl mussels.This study of the Billstaån restoration assessed ecosystem services by using methodology from Corporate Ecosystem Service Review (ESR) to identify priority services connected to the restoration and to get an overview of the expected restoration outcomes translated into ecosystem service thinking. 20 ecosystem services out of the 31 services assessed were deemed to be affected by the restoration, ten of them relating to the restoration project by having both high dependence and high impact in connection to the expected restoration outcomes. Ecosystem services connected to freshwater, erosion control, recreation and ecotourism, habitat, and energy provisioning were identified as priority based on monitoring interest and potential connection to market values.A second part to the study purpose was to test usability of ESR in the specific setting of the Billstaån restoration. As several issues related to framework functionality emerged during the study ESR was deemed less suitable for evaluating Billstaån than previously expected. This relates to how the strong business focus in ESR do not apply to the information needs in an ecological restoration context, and also to that several of the stakeholders not having a direct business interest in the restoration. As a tool for initial ecosystem services assessment ESR still helped in the process of starting the translation of expected restoration outcomes into ecosystem services thinking.To get another perspective than the business focus in ESR and to be able to work with scenarios to describe the development of ecosystem services in Billstaån Toolkit for Ecosystem Service Site-based Assessment is suggested for further studies. Such studies would also provide some quantitative values easier to include in restoration monitoring work for comparison over time.
