EFG F1.3 Freeze-thaw streams – 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 F1.3 Freeze-thaw rivers and streams. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: F1.3.web.map v1.0.

The distribution of freeze-thaw rivers and streams was mapped from the Global River Classification database (Ouellet Dallaire et al. 2018), including all reaches with with minimum temperature below 0°C.

Datasets

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.
