EFG F1.1 Perm upland streams – current maps
F1. Rivers and streams biome
This page provides information about the valid indicative distribution map for the ecosystem functional group F1.1 Permanent upland streams. For older or alternative maps, see here.
Methods
Here is the methods summary for Map code and version: F1.1.web.mix v2.0.
Freshwater ecoregions (Abell et al. 2008) were initially identified as containing permanent upland streams if: i) their descriptions mentioned features consistent with those identifed in the profile of the Ecosystem Functional Group; and ii) if their location was consistent with the ecological drivers described in the profile. The selected ecoregions were then clipped to exlude cold or dry climates (mean temperature of coldest quarter >0°C, mean annual preipitation >300mm) based on data from Karger et al. (2017). Major occurrences were mapped by intersecting the selected ecoregions with the distribution of 1st-3rd order streams taken from the RiverATLAS (v1.0) database at 30 arc seconds spatial resolution (Linke et al. 2019). The remaining areas within selected ecoregions (excluding freeze/thaw areas) were designated as minor occurrences.
