To develop a decision-support tool for the conservation of grassland birds in Switzerland, the Swiss Ornithological Institute has produced high-resolution maps (1 hectare) for five individual species, as well as a combined map for all five species. The individual species maps show the potential habitat differentiated according to occurrence status (from 2013 to the present) into ”confirmed”, ”probable”, ”unlikely“ and ”absent”. The maps are limited to grassland-dominated habitats in mountain zones I-IV and the summer grazing area. The species considered are the whinchat (Saxicola rubetra), the skylark (Alauda arvensis), the woodlark (Lullula arborea), the tree pipit (Anthus trivialis) and the meadow pipit (Anthus pratensis), all of which are conservation relevant and are dependent on extensive agricultural management. The maps refer to grassland-dominated habitats in mountain zones I-IV and the summer pasture areas. They allow for a quick and efficient assessment of the occurrence of the different species during the breeding season, as well as the meadows and pastures potentially suitable at the national scale. The maps support stakeholders from nature and landscape conservation in the planning of conservation measures and monitoring their success (e.g. action plans, local species promotion projects, spatial planning, ecological infrastructure, infrastructure projects (e.g. agricultural ameliorations, tourism, energy, etc.), projects for the regional promotion of biodiversity and landscape quality (from 2028, DZV)). The maps are updated annually to reflect new findings in a timely manner. Please consult the accompanying documentation (Anwendungshilfe, see documents) and observe the guidelines on data submission and license rights when using the maps. Further information on grassland birds is available in a separate factsheet (see documents). If you have any questions or remarks, please contact us at grasslandbirdmaps@vogelwarte.ch.
