Land Treatment Digital Library Version 2.0 Launch

By Forest and Rangeland Ecosystem Science Center April 1, 2026

The U.S. Geological Survey launched an updated version (2.0) of the Land Treatment Digital Library to improve user experience, include additional data, and enhance Bureau of Land Management access. 

The U.S. Geological Survey partners with the Bureau of Land Management (BLM) to create and maintain the Land Treatment Digital Library (LTDL) data and website. The LTDL is an online catalog of legacy land treatment information carried out on BLM lands in the western United States. The LTDL compiles many different types of land treatments, such as seedings, vegetation removals, and prescribed fire - and is used by land managers to help them make decisions about where, when, and how to implement future land treatments using the Land Treatment Exploration Tool. The LTDL houses information on over 70,000 treatments across the western United States.

The U.S. Geological Survey launched an updated version (2.0) of the LTDL to improve user experience, include additional data, and enhance BLM access. Notable additions to the website include interactive figures for each treatment polygon that display the monthly average temperature and precipitation from PRISM Climate Group at Oregon State University, and the annual vegetation cover from Multi-Resolution Land Characteristics Consortium. 

Since its original launch in 2009, the LTDL has become an important tool for resource managers to learn from restoration actions and the data are used for restoration planning through the Land Treatment Exploration Tool. Over 80 publications have utilized the LTDL to help address resource management questions and further the understanding of restoration science, which leads to more efficient and durable treatments.

Remotely Sensed Vegetation Cover Data for Treatment Polygons

This chart displays annual land cover and rainfall specifically for LTDL treatment polygon areas. Information from these charts can help resource managers understand the long-term vegetation trends from past treatments, alongside the context of annual precipitation and other fire and treatment disturbances.  This example is from a post-wildfire treatment. The fire and treatment occurred in 2007, which is delineated with a dashed red line for years of fire and a black line for the year of treatment. Before the fire, the area was dominated by shrubs (totaling ~30%), which plummeted to near zero immediately after the fire event. In the wake of the fire, bare ground briefly spiked to over 50% before being replaced by a surge in herbaceous plant cover, which remained the dominant cover (near 40%). While total shrub cover has steadily recovered to about 22%, it remains below pre-fire levels, and precipitation (shown as background bars) continues to fluctuate annually, influencing these recovery trends.
