This viewer consists of the following elements:
National Land Cover Database (NLCD) tree canopy cover geospatial datasets with spatial resolutions of 30 meters are produced by the United States Department of Agriculture (USDA) Forest Service. These data contain percent tree canopy estimates, as a continuous variable, for each pixel across all land covers and types. Tree canopy cover is derived from multi-spectral satellite imagery and other available ground and ancillary information.
Tree canopy products for the period 2011-2021 are available for the conterminous United States and can be accessed through the Multi-Resolution Land Characteristics (MRLC) website.
By default, the graph at the bottom and the upper right box display changes in tree canopy cover for all Native Lands in the conterminous United States. To explore a specific area, simply click on the site of interest or use the search bar to find the area. Once you click on the desired area, the graph and the value in the Upper Right Box will automatically update to reflect tree canopy cover changes for that specific location.
This viewer is presented here as a potential resource for Tribes to use in natural resource and climate adaptation assessment and planning. For more resources related to tribal climate & agricultural planning, explore NLAP’s other data dashboards and maps.
The NLCD products are created through a cooperative project conducted by the Multi-Resolution Land Characteristics Consortium (MRLC). The MRLC Consortium is a partnership of federal agencies, consisting of the U.S. Geological Survey, the National Oceanic and Atmospheric Administration, the U.S. Environmental Protection Agency, the U.S. Department of Agriculture, the U.S. Forest Service, the National Park Service, the U.S. Fish and Wildlife Service, the Bureau of Land Management and the USDA Natural Resources Conservation Service.
At this time Alaska, Hawaii, Puerto Rico, and the US Virgin Islands do not have tree canopy cover for every year in the series like MRLC produced for the Lower 48 states. Furthermore, only a portion of coastal Southeastern Alaska from Kodiak to the Panhandle is available, but not the entire state. Alaska, Hawaii, Puerto Rico, and the US Virgin Islands have data in the series only from 2011 and 2016.
