Major Land Resource Area (MLRA)
Major Land Resource Area (MLRA) including the publication Land Resource Regions and Major Land Resource Areas of the United States, the Caribbean, and the Pacific Basin (USDA Agriculture Handbook 296, 2022).
Land Resource Regions (LRR) and Major Land Resource Areas (MLRA) are delineated in the 2022 MLRA Geographic Database and described in USDA Agriculture Handbook 296. The handbook is used as a basis for decisions regarding national and regional land resource issues targeting efforts in education, finance, and technical services. It is also used to identify needs for research and additional inventories, as well as a vehicle for extrapolating research results across political boundaries. The handbook also serves various agencies within USDA by organizing and operating conservation program and other land resource and management programs.
