EFG F3.2 Constructed lacustrine wetlands – current maps
F3. Artificial wetlands biome
This page provides information about the valid indicative distribution map for the ecosystem functional group F3.2 Constructed lacustrine wetlands. For older or alternative maps, see here.
Methods
Here is the methods summary for Map code and version: F3.2.web.orig v1.0.
Freshwater ecoregions (Abell et al. 2008) were identified as containing major or minor occurrences of these functional groups if: i) their descriptions mentioned features consistent with those identifed in the profile of the Ecosystem Functional Group; and ii) if their location was consistent with the ecological drivers described in the profile. The selections were check by expert reviewers. Occurrences were mapped at 30 arc seconds spatial resolution.
Datasets
