EFG MFT1.2 Intertidal forests – current maps

MFT1. Brackish tidal biome

This page provides information about the valid indicative distribution map for the ecosystem functional group MFT1.2 Intertidal forests and shrublands. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: MFT1.2.web.orig v2.0.

The indicative map of Intertidal forests and shrublands (MFT1.2) was developed by resampling the known global distribution of mangrove forests for the year 2000 mapped by Giri et al. (2011). We used a buffer of 1km around the distribution data and a 30 arc second grid, thus large aggregations (> 1km²) are depicted as major occurrences, and the buffer areas with small occurrences are shown as minor occurrences. The original high-resolution data is available at UNEP-WCMC.
