Development of high-resolution maps for targeted protection measures

The main objective of this project is to develop nationwide decision-support tools for Switzerland that identify where and how specific bird species can be effectively promoted through targeted conservation measures. These tools consist, on the one hand, of high-resolution spatial maps and, on the other hand, of accompaying material that provide background information as well as specific recommendations for each map category and species. Depending on the habitat type (e.g. grasslands or forests), additional objectives are defined.

The tools are being developed through an iterative process in close collaboration with the key stakeholder groups to ensure its practical relevance and user-friendliness. The process begins with an assessment of user needs, followed by the development of a concept for the overall product, including the map content, the format and content of the accompanying material, and the most suitable platform(s).
The workflow for map production is first developed based on a few pilot species and is then gradually extended to additional species. Depending on the selected map categories, various data sources available across Switzerland are processed and combined. These include, for example, bird observation data from standardized or species-specific monitoring programs, checklist data, and opportunistic observations contributed by volunteers (citizen science data). To characterize habitats, we use high-resolution environmental variables, such as nationwide high-resolution LiDAR (Light Detection and Ranging) data. The workflow is designed so that the maps can be updated regularly.
In parallel with the maps, practice-oriented guidance materials are being developed. These complement the maps with background information and, depending on the map category and species, provide specific recommendations for the effective planning and implementation of conservation measures.
