This archive contains information for *F2.7 Ephemeral salt lakes*, a ecosystem functional group (EFG, level 3) of the IUCN Global Ecosystem Typology (https://global-ecosystems.org/).

General notes on maps:
======================

The maps show areas of the world containing major or minor occurrences of *F2.7 Ephemeral salt lakes*. Minor occurrences are areas where an EFG is scattered in patches within matrices of others or where they occur in substantial areas but only within a segment of a larger region.

The maps were designed to be indicative of global distribution patterns and are not intended to represent fine-scale patterns. Given bounds of resolution and accuracy of source data, the maps should be used to query which EFG are likely to occur within areas, rather than which occur at particular point locations.

Methods for this map:
=====================

Location of ephemeral lakes was taken from global lake databases (Lehner and Döll 2004; types 1 and 3 from Messager et al. 2016), intersected with estimates of ephemeral surface water (classes 9 and 10 from Pekel et al. 2016) and the distribution of arid and semi-arid, endorheic basins (Linke et al. 2019). Occurrences were aggregated to 10 minutes spatial resolution. Occurrences were aggregated to 10 minutes spatial resolution.
