Published

June 7, 2024

This page provides information about the valid indicative distribution map for the ecosystem functional group TF1.5 Episodic arid floodplains. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: TF1.5.web.map v2.0.

Locations of pan, brackish and saline wetlands were taken from the Global Lakes and Wetlands Database GLWD3 class 7 from Lehner and Döll (2004).

Datasets

GLWD-2004 (Lehner and Döll 2004):

Source of validated distribution records. Resolution: ca. 1km2, static. Accuracy evaluation: quantitative (subsets).
