EFG T3.3 Cool temp heathlands – current maps

T3. Shrublands and shrubby woodlands biome

This page provides information about the valid indicative distribution map for the ecosystem functional group T3.3 Cool temperate heathlands. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: T3.3.web.alt v4.0.

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.

Datasets

EarthEnv-LandCover-v1.0 (Tuanmu et al. 2014):

Source of global landcover product. Resolution: ca. 1km2, static. Accuracy evaluation: accuracy weighted consensus.

Ecoregions-North-America-1997 (CEC 1997):

Source of biogeographical range. Resolution: variable (polygons), static. Accuracy evaluation: qualitative (experts judgement).

Landcover-North-America-2016 (Latifovic et al. 2016):

Source of regional landcover product. Resolution: <1km2, static. Accuracy evaluation: derived from sources.

Resolve-Ecoregions-2017 (Dinerstein et al. 2017):

Source of biogeographical range. Resolution: variable (polygons), static. Accuracy evaluation: qualitative (experts judgement).
