Central Research Questions
This project is led by Karl-Olof Bergman. Its objectives are to determine habitat thresholds by establishing the minimum habitat requirements necessary for species survival, to map functional areas by identifying and mapping regions that have the potential to support sensitive species based on habitat thresholds, and to enhance conservation efforts by providing recommendations for cost-effective conservation actions to improve habitat quality and connectivity.
Background and Aims
The research, conducted by Karl-Olof Bergman, focuses on identifying key habitat thresholds essential for the survival of various species in southern Sweden. This project aims to guide effective conservation strategies by determining the specific habitat requirements needed to support biodiversity in landscapes affected by habitat loss. Key features studied include tree species, investigating old oaks, ash, wych elm, and Norway maple trees, as well as semi-natural grasslands, analyzing the extent and condition of grasslands. This ongoing research is crucial for developing effective conservation plans that address biodiversity loss in southern Sweden. By identifying and mapping critical habitat thresholds, the project aims to support the survival of diverse species and maintain ecosystem health.
Methods
Data collection utilizes extensive datasets from citizen science and professional surveys to map large trees and grasslands. Species analysis compiles and analyzes data on species occurrences, focusing on plants, mosses, lichens, fungi, and invertebrates. Modeling habitat thresholds uses statistical models to predict species occurrences based on habitat amounts and identify critical habitat thresholds.
Key findings
Critical habitat amounts have been identified, specifying the habitat amounts necessary to support various species. Functional landscapes have been mapped, identifying regions that meet these habitat thresholds and can support a diverse range of species. Conservation priorities have also been highlighted, pointing to areas with significant potential for habitat restoration and conservation.
Conservation implications
Guided conservation actions provide actionable data to help conservation practitioners focus efforts on the most critical areas. Habitat restoration is emphasized as important for meeting identified thresholds, ensuring the long-term survival of species. Public engagement is also encouraged through the use of citizen science data to enhance conservation strategies and foster community involvement.
