What species habitat classification is used for PECBMS data?
The PECBMS currently uses two versions of species habitat classification at the moment: single European species habitat classification and BioGeo regional species habitat classification.
This species habitat classification for main habitat types (farmland, forest and other) has been developed using improved procedure accepted at the PEBCMS workshop in Prague in 2005.
BioGeo regional species habitat classification is based on the expertise of regional coordinators, who were responsible for the production of regional species lists in cooperation with all relevant experts within their regions. Distinguished regions were: ´Continental´, ´Atlantic´, ´Mediterranean´, and ´Boreal´. Within these regions, coordinators classified each species for main habitat types (farmland, forest and other). BioGeo regional species habitat classification for each region is specified in the table, columns ´Continental´, ´Atlantic´, ´Mediterranean´, and ´Boreal´.
Single European species habitat classification is been created as a combination of the BioGeo regional habitat characteristics of each species into the general species habitat classification unified for the whole Europe. For this general, single European classification, a species was assigned to a particular habitat category if:
- at least two regions provided their classification and all providing regions agreed, or
- only one region (minority) classified a species differently than the others.
In some cases a species classification was provided by one region only, but if the species was concentrated in that region and didn´t occur elsewhere in Europe, the species BioGeo regional classification was accepted as single European too. If regional classifications differed completely, a species was generally considered as ´other species´.
The latest single European species habitat classification is defined in the table, column ´Europe´.
