20220831 11075000 1.0 TRUE 150000000 5000 Mangroves Presence/Absence grid Mangroves presence/absence Summary: This dataset represents the most current distribution of mangroves in the southeastern United State based on expert knowledge. These data provide a baseline for continued monitoring of the distribution and abundance of mangroves throughout the southeastern United States and are a significant update to previously best available maps of mangrove distribution. Accurate information regarding range shifts is particularly critical for foundation plant species like mangroves, as it provides a basis for understanding the cascading effects of range expansion on ecosystems and the human communities that depend on their ecosystem services. Methods: A team of scientists from Northeastern University, the U.S. Geological Survey, The Nature Conservancy, and other partner organizations created a new mangrove map depicting the current (as of 2021) distribution of mangroves in the southeastern United States, based on a synthesis of existing datasets and expert knowledge. Each grid cell has a resolution of 0.125 degrees, or approximately 14 x 16 km, within which the presence or absence of mangroves has been independently determined using existing datasets and expert knowledge. These data provide a baseline for continued monitoring of the distribution and abundance of mangroves throughout the southeastern United States. Each grid cell is categorized as 1 –mangroves present or 2 –mangroves absent. The grid is symbolized in the map with blue cells indicating presence of mangroves and gray cells indicating absence of mangroves.
