Arid and Semi-Arid Lands

Science Center Objects

The Status and Trends Program provides timely, quality science about arid and semi-arid lands to meet the needs of resource management  bureaus within Interior and other science and resource management organizations.

More information about Status and Trends program arid and semi-arid lands research is available from  the "Related Science" tab on the top navigation or from the links below.

Disturbance History in Natural Communities

Science Center: Forest and Rangeland Ecosystem Science Center

We are using dendrochronology techniques, field-based studies of successional processes, and other approaches to investigate the natural disturbance histories of different ecosystems in the Intermountain West, from semi-arid, sagebrush shrublands to aspen forests in mountainous environments.

Restoration Assessment & Monitoring Program for the Southwest (RAMPS)

Science Center: Southwest Biological Science Center

The Restoration Assessment and Monitoring Program for the Southwest (RAMPS) seeks to assist U.S. Department of the Interior and other land management agencies and private partners in developing successful restoration strategies for dryland ecosystems of the southwestern United States.

Ecohydrology and Climate Change in Drylands

Science Center: Southwest Biological Science Center

Drylands cover 40% of the global terrestrial surface and provide important ecosystem services. However, climate forecasts in most dryland regions, especially the southwest U.S., call for increasing aridity.

Aridlands Disturbances and Restoration Ecology

Science Center: Western Ecological Research Center

Desert landscapes are rapidly changing due to increases in invasive plant species, frequency of wildfires, urban and energy development, recreational use, military training, and climate variation. USGS researchers are investigating these changes and providing managers with key information that can be used to manage natural resources more effectively.
