These geodatasets are the result of the work carried out in Churko, G., Szerencsits, E., Aldrich, A., & Schmidt, B. R. (2024). Spatial analysis of the potential exposure of amphibians to plant protection products at the landscape scale. Basic and Applied Ecology, 76, 14–24. https://doi.org/10.1016/j.baae.2024.02.004, which aimed at estimating the potential exposure of amphibian populations to plant protection products (PPPs). The specific objective was to describe the spatial overlap between the terrestrial habitats of amphibian populations and agricultural crops where PPPs are potentially used, in order to identify exposure hotspots and, consequently, areas requiring measures to protect amphibians from plant protection products. The individual datasets can be useful for other analyses in the field of amphibian conservation, particularly for the planning, prioritization, and spatial coordination of ecological infrastructure such as new ponds, agricultural biodiversity enhancement areas, and protected areas. Integration with other datasets, such as the amphibian breeding sites from the info fauna karch data center, is necessary for this purpose, as amphibians dynamically utilize a landscape by colonizing new breeding sites.
The results include the following geodata sets:
Maps showing the suitability of terrestrial habitats for eleven amphibian species, created usinga multi-scale Species Distribution Model (SDM) based on occurrence records from the infofauna karch database. The 11 species include: Alytes obstetricans, Bombina variegata, Bufobufo, Epidalea calamita, Ichthyosaura alpestris, Hyla arborea, Lissotriton helveticus, Lissotriton vulgaris, Rana dalmatina, Rana temporaria, and Triturus cristatus.
Dispersal probability maps for the same eleven species, created by calculating potential dispersal routes between known amphibian breeding sites based on the results of the SDM.
Two maps showing agricultural parcels that serve as suitable terrestrial habitats and dispersalareas for amphibians. These two vector datasets integrate the findings mentioned above witha parcel-level database of agricultural land use by spatially overlaying suitable habitats and dispersal routes for each species. The two datasets distinguish between the basic agricultural parcels and overlaying elements such as Biodiversity Promotional Areas, small structures like rockpiles and logs, and trees. They thus identify agricultural areas located in the vicinity of amphibian breeding sites that are potentially used as terrestrial habitat and/or for dispersing between amphibian breeding sites.
A subset of these datasets are available to explore on map.geo.admin.ch with metadata available in GE/FR/EN on www.geocat.ch.
