Status and Trends Program

Populations and Health

Effective species conservation requires an understanding of the distribution, abundance, and health of organisms across a variety of  spatial and temporal scales. Visit the links below to see how USGS tracks the status and trends of diverse organisms, including birds, pollinators, and fish across a variety of spatial scales in a diversity of ecological systems.

Climate-driven state shifts in the Prairie Pothole Region: assessing future impacts relevant to the management of wetland habitats critical to waterfowl

The Prairie Pothole Region (PPR) covers parts of five states and three Canadian provinces. The region contains millions of wetlands that annually produce 50-80% of the continent’s duck population. Previous modeling efforts indicated that climate change would result in a shift of waterfowl habitat from the central PPR to the southeast PPR where the majority of wetlands have been drained....

Temporal and spatial patterning of aquatic macroinvertebrate communities in response to changing environmental conditions

An increased understanding of prairie-pothole-wetland macroinvertebrate dynamics is crucial to better inform conservation strategies related to waterfowl production, biodiversity enhancement, and wetland function/health maintenance. Wetlands in general are highly variable in space and time, and wetland macroinvertebrates are adapted to this great variability. Wetland ecosystems are also...

Bird Banding Laboratory

The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America.  This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...

Alpine Wildlife and Snowpack Dynamics in the North Cascades

Mountain ecosystems are expected to change with continued reductions in annual snowpack that have been observed worldwide over the past half-century. Recent snow droughts in North America have been attributed to unusually warm temperatures that cause winter precipitation to fall as rain, rather than snow. Many species of alpine wildlife depend on snowpack for insulation from extreme cold and...
