EFG F1.4 Season upland strems – current maps

F1. Rivers and streams biome

Published

June 7, 2024

This page provides information about the valid indicative distribution map for the ecosystem functional group F1.4 Seasonal upland streams. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: F1.4.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 the selected ecoregions, major occurrences were mapped using 1st-4th order streams (3km buffer) taken from the RiverATLAS (v1.0) database (Linke et al. 2019). The remaining areas of selected ecoregions were mapped as minor occurrences.

Datasets

FEOW-2008 (Abell et al. 2008):

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

HydroAtlas-1.0 (Linke et al. 2019):

Source of Hydrography. Resolution: <1km2, static. Accuracy evaluation: derived from sources.

How to use the data

Available files

Following maps are considered current and valid indicative distribution maps for this ecosystem functional group. Web navigation maps are optimised for use in webapps, but they have similar methods and differ only in details of format and processing.

  • Indicative Map (code: F1.4.IM.grid, version v2.0)
  • Web navigation (code: F1.4.web.map, version v1.0)

You can download geospatial data for this map from the following sources:

F1.4.IM.grid (v2.0): Google Cloud bucket :: Zenodo repository (bundle of maps)

F1.4.web.map (v1.0): Google Cloud bucket :: Zenodo repository (bundle of maps) :: Zenodo repository (EFG map) :: Mapbox tileset :: Earth Engine assets

Note that you need to login to some services like mapbox or earthengine, and in some cases you also need to request access to the files.
