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.

Managing Organizations

Since 1994, Canada, Mexico and the United States have collaborated in protecting North America's environment through the North American Agreement on Environmental Cooperation (NAAEC).

The NAAEC came into force at the same time as the North American Free Trade Agreement (NAFTA) and marks a commitment that liberalization of trade and economic growth in North America would be accompanied by effective cooperation and continuous improvement in the environmental protection provided by each country.
