This page provides information about the valid indicative distribution map for the ecosystem functional group MT1.4 Boulder and cobble shores. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: MT1.4.web.map v1.0.

Marine ecoregions (Spalding et al. 2008) containing rocky shorelines and boulder and cobble shorelines, respectively, were identified by consulting regional substrate maps, imagery available in Google Earth (to exclude ecoregions with extensive sandy or muddy shores) and expertise of authors, proofed by specialist reviewers.

Datasets

MEOW-2008 (Spalding MD et al. 2008):

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