Data
The AEnZ is based on the Environmental Stratification of Europe (EnS), the
European Soil Database (ESDBv2), the TOPsoil Organic Carbon (OCTOP) and the
Global Digital Elevation Model (GTOPO30). In this section a short description of
those databases is presented.
Description and Characterization of the Environmental Zones (EnZ)
The EnS consists of 84 strata, which have been aggregated into 13 environmental
zones (EnZs) based on divisions of the mean first principal component score of the
strata. The only exception is the Mediterranean mountain zone, which was separated
based on altitude. The dataset covers a 'Greater European Window' (11°W-32°E,
34°N-72°N), encompassing the EU27+ with extensions to the East and South.
The EnS has been constructed using tried and tested statistical procedures so
that the strata are unambiguously determined and, as far as possible, independent
of personal bias. It forms an appropriate stratification for stratified random
sampling of ecological resources, the selection of sites for representative studies
across the continent and for the provision of strata for modelling exercises and
reporting at European scale.
