This archive contains information for *T3.3 Cool temperate heathlands*, 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 *T3.3 Cool temperate heathlands*. 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:
=====================

Major and minor occurrences were identified using consensus land-cover maps (Tuanmu et al. 2014; Latifovic et al. 2016), then cropped to selected terrestrial ecoregions at 30 arc seconds spatial resolution (Dinerstein et al. 2017; CEC 1997). Ecoregions were selected if they contained areas mentioned or mapped in published regional studies (Loidi et al. 2015; Luebert & Pliscoff 2017), or if: i) their descriptions mentioned features consistent with those identified in the profile of the Ecosystem Functional Group; and ii) if their location was consistent with the ecological drivers described in the profile.
