Status and Trends Program


Information about the status and trends of natural resources is required at a variety of spatial and temporal scales to detect changes that may signal degradation or improvement of natural systems, such as habitat, or to identify new or emerging conditions that signal the need for management action or further investigative research.

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....

Fish and Wildlife seasonal and temporary wetland assessment

The Prairie Pothole Region supports some of the most productive wetlands in the world for waterfowl. Up to 90% of seasonal and temporary wetlands have been lost in areas of the PPR due to the conversion of grasslands to croplands and the drainage of wetlands. Department of the Interior Waterfowl Production Areas (WPA) and National Wildlife Refuges (NWR) in North Dakota, South Dakota, and...

Development, application, and refinement of a systems model fo prairie wetlands

NPWRC is developing, applying, and refining an integrated, process-based, systems model for prairie-pothole wetlands to facilitate forecasts of how climate and land-use change will affect wetland processes and biota. The Pothole Hydrology Linked System Simulator model (PHyLiSS) simulates changes in hydrology, water chemistry, plant communities, invertebrates, and other biota as a result of...

Inventory, mapping, estimation, and monitoring of least tern and piping plover habitats on the upper Missouri River using satellite imagery

Emergent sandbar maps of the Missouri River produced by Northern Prairie Wildlife Research Center continue to be used by the U.S. Army Corps of Engineers and U.S. Fish and Wildlife Service to monitor and manage critical breeding habitat for the endangered Interior population of least terns and the threatened Northern Great Plains population of piping plovers.  These maps have been created and...

Long-term changes in wetland and prairie landscapes

Over the past 50 years, wetlands in the Prairie Pothole Region of the northern Great Plains have experienced a wide range of climatic conditions (severe drought to extreme wet), expansion of invasive species such as hybrid cattail, and disturbances (e.g., grazing, burning, flooding, drainage).  In this study, we revisited wetlands that Stewart and Kantrud (1971) studied 50 years ago to...

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...

RestoreNet: Distributed Field Trial Network for Dryland Restoration

U.S. Geological Survey (USGS) researchers and land managers are co-producing a network of restoration field trial sites on DOI and surrounding lands in the southwestern U.S. The network systematically tests restoration treatments across a broad range of landscape, soil, and climate conditions. Each site in the network is used to test suitable seed mixes and treatments that promote plant...
