Welcome to the Land Treatment Digital Library Web Site

The Land Treatment Digital Library (LTDL) was created by the U.S. Geological Survey to catalog legacy land treatment information on Bureau of Land Management lands in the western United States. The LTDL can be used by federal managers and scientists for compiling information for data-calls, producing maps, generating reports, and conducting analyses at varying spatial and temporal scales. The LTDL currently houses 66,491 treatments from BLM lands across 14 states. Users can browse the map below to find information on individual treatments, perform more complex queries  to identify a set of treatments, and view graphs  of treatment summary statistics.
