Description of the data and file structure
Dataset description:
The dataset contains Area of habitat (AOH) maps for 28 bumblebees (23 species and 5 subspecies) occurring in Italy. The maps reveal the geographic distribution of the species habitat within their global range. Each map is available in GeoTIFF format. Raster pixel values are equal to 0 if they fall within the distribution range but do not represent available habitat for the species. Pixel values are equal to 1 if they represent available habitat for the species withi its distribution range.
Methods description:
We obtained occurrence points for 28 bumblebees (23 species and 5 subspecies) from the Atlas of European bees (Rasmont 2015). We derived a distribution range for each species from its occurrence points using the freely accessible map ‘Admin-1 State and provinces' of the Natural Earth database (nauralearthdata.com). The map contains data on internal first order administrative boundaries worldwide, with a resolution of 1:10m. We performed an intersection between the species occurrence points and the administrative boundaries map, retaining only the regions of the map intersected by the species occurrence points. We linked the species to their natural habitat using Copernicus Global Land Service Land Cover (CGLS-LC100) 2019 classes as a habitat surrogate. Species-Habitat associations and altitude limits were based on the current knowledge of the biology of target species, as referenced in scientific literature and species datasets. A binary classification was compiled to link species habitat to land cover classes. Altitude limits (minimum and maximum) were compiled for each species. The CGLS-LC100 map was combined with altitude information from the Shuttle Radar Topography Mission (USGS EROS Archive 2019) to produce a base map. We used the species ranges to mask the area of the base map which is found out of the species range. The base map was reclassified according to species' habitat requirements to produce the AOH maps.
