Weed-Suppressive Bacteria – Testing a Control Measure for Invasive Grasses in the West

Recent popular news has implied that Weed-Suppressive Bacteria (WSB) holds promise for cheatgrass control, yet a lack of peer-reviewed research exists to support this claim. USGS researchers stepped up to the challenge of objectively and rigorously evaluating the effectiveness of WSB for controlling exotic annual grasses, such as Cheatgrass and Medusahead, while also examining its impact on native...

Standardized Emergency Stabilization and Rehabilitation Monitoring Protocols (ES&R)

Fire rehabilitation programs have existed within federal agencies since the early 1960s. The U.S. Forest Service and Bureau of Land Management are the largest users of emergency stabilization and rehabilitation (ES&R) funds, but these agencies only sporadically implement proposed monitoring and rarely use common protocols. As a result, it is impossible to draw scientifically credible conclusions...

Wildfire Impacts, and Post-Fire Rehabilitation and Restoration

Land use and unintentional (e.g., wildfire) disturbances are increasingly dominant factors affecting land-use planning and management of semiarid landscapes, particularly in sagebrush steppe rangelands. In the last 10-20 years, wildfires are occurring more frequently and increasingly in very large burn patches.

Plant Responses to Temperature and Water Limitation

Weather and climate impacts on dominant native perennials must be understood in order to efficiently manage our western landscapes. We use an ecophysiological approach, linking to population, community, and landscape ecology, to understand the impacts and responses of plants on or to their environment.

Invasive Species Ecology

Invasive annual grasses are the greatest threat to shrub-grassland ecosystems of the Intermountain West. These grasses grow earlier in the season than native plants, usurping water and nutrients, and making survival and reproduction difficult for native species. They also change the fire regime within the ecosystem, creating more frequent and larger wildfires. We are attempting to understand the...

Information for Golden Eagle Management

This work provides basic information for managing golden eagles in the context of the Bald and Golden Eagle Protection Act (16 U.S.C. 668-668d). The recent development of energy resources, such as wind, oil, gas, and solar, can potentially affect landscapes in ways that require changes in golden eagle management practices. Our work emphasizes priority information needs identified by the USGS and U...

Integrating Science and Adaptive Land Management

Widespread habitat deterioration due to fire and invasive species in the Great Basin have created a need for coordination across land agencies and between science and management activities in the Great Basin.

Indicators of Rangeland Health

Rangelands are natural ecosystems where the native vegetation consists predominantly of grasses, grass-like plants, forbs, or shrubs. Rangelands include natural grasslands, savannas, shrublands, oak and pinyon-juniper woodlands, many deserts, tundra, alpine communities, marshes, and wet meadows.

Conservation Issues for Sage-Grouse and Sagebrush Ecosystems

Greater sage-grouse (Centrocercus urophasianus) are the most visible of >350 plant and wildlife species that depend on sagebrush. Their conservation status was determined by the U.S. Fish and Wildlife Service in 2010 to be warranted for listing but precluded by higher priorities. Habitat and population fragmentation, coupled with inadequate regulatory mechanisms to control development on public...

Land Treatment Digital Library

The LTDL was created by the U.S. Geological Survey (USGS) to catalog information about land treatments on Federal lands in the western United States for all interested parties. The flexible framework of the library allows for the storage of a wide variety of data in different formats. The LTDL currently stores previously established land treatments or what often are called legacy data. The project...
