Land Management Research Program

The Land Management Research Program conducts research to improve the effectiveness of land management and inform restoration of priority ecosystems on millions of acres including public lands such as National Parks, refuges, and other critical landscapes that support the biodiversity of fish, wildlife, and plant species, as well as thriving economies.

Ecosystem Research

Looking towards mountain peaks from shore of Knox Lake

The Nation’s ecosystems are complex, dynamic, and exposed to a rapidly changing climate among other threats.  USGS scientists study how ecosystems function, the impacts of stressors, and make predictions about their future to improve restoration and management outcomes.

Invasion resistance varies by fuel break type in sagebrush ecosystems Invasion resistance varies by fuel break type in sagebrush ecosystems

Background Wildfire is an increasingly important driver of changes within sagebrush (Artemisia spp. L.) ecosystems of the western USA, often resulting in increased spread of exotic annual grasses, such as cheatgrass (Bromus tectorum L.), and subsequent losses of native vegetation and wildlife habitat. Fuel breaks— areas of land treated to reduce or redistribute fuel loads — are widely...

Range-wide population trend analysis for greater sage-grouse (Centrocercus urophasianus)—Updated 1960–2024 Range-wide population trend analysis for greater sage-grouse (Centrocercus urophasianus)—Updated 1960–2024

Greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) are at the center of State and national land-use policies largely because of their unique life-history traits as an ecological indicator for the health of sagebrush ecosystems. This updated population trend analysis provides State and Federal land and wildlife managers with the best available science to help guide...

Precipitation timing mediates life-stage and population-level associations with climate for an indicator species Precipitation timing mediates life-stage and population-level associations with climate for an indicator species

Global climate change is contributing to declines in biodiversity, although changes vary across geographic regions and species. The iconic greater sage-grouse (Centrocercus urophasianus; sage-grouse) is central to conservation within the North American sagebrush ecosystem, yet its vulnerability to climate effects remains poorly understood. We used hierarchical models to explore weather...

Advancing the Environmental DNA Toolkit for Ecosystem Monitoring and Management

The emerging field of Environmental DNA (eDNA) analysis allows characterization of species presence and community biodiversity by identifying trace amounts of genetic material left behind as organisms move through their environments. EESC scientists have been using eDNA technologies to detect native and rare species and as community biomonitoring tools.

Waterfowl Research

Scientists at the USGS Alaska Science Center have conducted research on waterfowl species (ducks, geese, and swans) in Alaska since the 1970s. Because Alaska is an international crossroads of migratory bird flyways, with millions of birds from Asia and North America breeding in Alaska each summer, USGS research has also taken place in adjacent countries (Russia, Japan, Canada, Mexico) and in the...
