1. Restoration of semi-natural grasslands : Impacts on biodiversity, ecosystem services and stakeholder perceptions
Sammanfattning : Humans play a major role shaping the living conditions for not only ourselves, but also all other species on Earth. In fact, some species-rich habitat types require human management to uphold the biodiversity and related ecosystem services. LÄS MER
2. Conservation of semi-natural grasslands : Effects of different management methods on biodiversity
Sammanfattning : Species-rich semi-natural grassland are valuable habitats in the agricultural landscape as they may contain a high diversity of both plant and animal species, as well as provide essential ecosystem services like pollination. To keep these habitats open and to maintain the biodiversity in them, management like grazing or mowing is necessary. LÄS MER
3. Biological diversity values in semi-natural grasslands : indicators, landscape context and restoration
Sammanfattning : Semi-natural grasslands, which are a declining and fragmented habitat in Europe, contain a high biodiversity, and are therefore of interest to conservation. This thesis examines how plant diversity is influenced by the landscape context, and how plant and fungal diversity can be targeted by practical conservation using indicator species and congruence between species groups.

4. Plant species richness and community assembly in Swedish semi-natural grasslands
Sammanfattning : .... LÄS MER
5. Land Use Change in Space and Time : implications for plant species conservation in semi-natural grasslands
Sammanfattning : Land use change has during the last century altered the traditional rural landscape in Sweden, resulting in a major decline in species diversity. Traditional small-scale farming, with a remarkably high small-scale species richness, has changed in favour of rationalized agriculture, and many semi-natural grasslands, i.e. LÄS MER
