EFG M1.10 Rhodolith beds – current maps

M1. Marine shelf biome

This page provides information about the valid indicative distribution map for the ecosystem functional group M1.10 Rhodolith/Maërl beds. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: M1.10.WM.nwx v1.0.

Distribution of rhodolith beds was taken from spatial predictions of suitable habitats for rhodolith forming species at global scales, including both tropical - warm temperate and polar - cold temperate affiliated rhodolith species (Fragkopoulou et al. 2021). Maps have a spatial resolution of 5 arc-minute.
