  3. 22. Habitat types in relation to bird diversity in boreal forestry landscapes in Sweden

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Engla Grönvall; [2023]
    Keywords : Biodiversty; Forestry; Bird diversity; Habitat types; Species Richness;

    Abstract : Boreal forests in Europe are intensively managed for timber and pulp production, resulting in decreased biodiversity, and in the long-term leading to a reduced number of functioning ecosystem services. To develop a more sustainable forest management it is important to investigate what features and habitat types are needed to preserve a high diversity of species within the forestry landscapes.
