EFG T6.4 Temp alpine grasslands – current maps

T6. Polar/alpine (cryogenic) biome

Published

June 7, 2024

This page provides information about the valid indicative distribution map for the ecosystem functional group T6.4 Temperate alpine grasslands and shrublands. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: T6.4.web.orig v1.0.

Terrestrial ecoregions containing major or minor occurrences of this ecosystem functional group were identified by consulting available ecoregion descriptions (Dinerstein et al. 2017), global and regional reviews, national and regional ecosystem maps, locations of relevant examples, and proofed by expert reviewers. Consequently they are coarse-scale indicative representations of distribution, except where they occupy small ecoregions. Ecoregions were mapped at 30 arc second spatial resolution.

Datasets
