This archive contains information for *MT1.4 Boulder and cobble shores*, a ecosystem functional group (EFG, level 3) of the IUCN Global Ecosystem Typology (https://global-ecosystems.org/).

General notes on maps:
======================

The maps show areas of the world containing major or minor occurrences of *MT1.4 Boulder and cobble shores*. Minor occurrences are areas where an EFG is scattered in patches within matrices of others or where they occur in substantial areas but only within a segment of a larger region.

The maps were designed to be indicative of global distribution patterns and are not intended to represent fine-scale patterns. Given bounds of resolution and accuracy of source data, the maps should be used to query which EFG are likely to occur within areas, rather than which occur at particular point locations.

Methods for this map:
=====================

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.
