Major land resource units (MLRU) in the United States are defined by the Natural Resources Conservation Service as geographic areas with similar soil, water resources, climate, vegetation, and land-use features. As such, they are important to determining terrestrial sequestration potential.
The MLRU areas within the U.S. portion of the Plains CO2
Reduction Partnership region are shown on the map below. Click

U.S. 2002 Major Land Resource Area Map
The U.S. 2002 Major Land Resource Area (MLRA) map is a polygon coverage of the land resource regions
and MLRAs of the conterminous United States and is available for the entire
U.S. portion of the Plains CO2 Reduction study area. The MLRAs are subregions of the land
resource regions and comprise smaller homogeneous areas. The scale of this coverage is 1:2,000,000 and
was developed and characterized by the Natural Resources Conservation Service. It represents land
resource regions characterized by a particular pattern of soils, climate, water resources, and land
