North American Blue Carbon, 2017
The North American Blue Carbon map shows the distribution of salt marsh, mangrove, and seagrass habitats in North America. Data were compiled from international (UNEP), national (Conabio, US Geological Survey and the US National Wetlands Inventory), state and provincial sources as well as from individual investigators. This map has been updated with improved information on seagrass distribution, including replacement of point data with polygon data for seagrass habitat along the Pacific Northwest coastline. Although this dataset represents the most comprehensive North American spatial distribution of blue carbon to date, many seagrass and salt marsh habitats have yet to be mapped.
