EFG TF1.4 Seasonal floodplain marshes – current maps
TF1. Palustrine wetlands biome
This page provides information about the valid indicative distribution map for the ecosystem functional group TF1.4 Seasonal floodplain marshes. For older or alternative maps, see here.
Methods
Here is the methods summary for Map code and version: TF1.4.web.map v1.0.
Major occurrences of freshwater marshes and floodplains were taken from the Global Lakes and Wetlands Database (Lehner and Döll 2004). Occurrences in boreal and polar climates were excluded by removing KoeppnGeiger_classes>26 in Beck et al. (2018). Additional areas with minor occurrences identified in selected freshwater ecoregions (Abell et al. 2008). Ecoregions were selected 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.
Datasets
FEOW-2008 (Abell et al. 2008):
Source of biogeographical range. Resolution: variable (polygons), static. Accuracy evaluation: qualitative (experts judgement).
