EFG F1.2 Perm lowland rivers – current maps
F1. Rivers and streams biome
This page provides information about the valid indicative distribution map for the ecosystem functional group F1.2 Permanent lowland rivers. For older or alternative maps, see here.
Methods
Here is the methods summary for Map code and version: F1.2.web.map v1.0.
Freshwater ecoregions (Abell et al. 2008) were identified as containing occurrences of these functional groups 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. Within these areas, major occurrences were mapped using stream orders 4-9 taken from the RiverATLAS (v1.0) database (Linke et al. 2019) combined with global estimates of surface water phenology (classes 1, 2 and 7 from Pekel et al. 2016). The remaining area of selected ecoregions was designated as minor occurrences.
Datasets
