EFG M1.5 Marine animal forests – current maps
M1. Marine shelf biome
This page provides information about the valid indicative distribution map for the ecosystem functional group M1.5 Photo-limited marine animal forests. For older or alternative maps, see here.
Methods
Here is the methods summary for Map code and version: M1.5.web.orig v1.0.
These are ecosystem functional groups that are widespread through the global extent of the marine shelf biome. Reliable data on their precise distribution are limited. To represent regional uncertainty, their indicative distributions were mapped in as minor occurrences through the full extent of the marine ‘shelf’ base layer as mapped by Harris et al. (2014b). Occurrences were converted to 30 arc second spatial resolution.
