Status and Trends Program

Stressors

The status and trends of organisms, habitats and ecosystems is often controlled by environmental and
anthropogenic stressors that have the potential to impact the health and productivity of lands and waters
of management concern.

Assessment of pattern tile drainage on wetland hydrology and ecosystem services in the Prairie Pothole Region

Prairie Pothole Region wetlands provide numerous ecological services to society such as wildlife habitat, water storage, and carbon sequestration. Agricultural production in the region has been enhanced through the expanded installation and use of subsurface drainage systems, but these systems may have a negative impact on the region’s wetlands, including those protected by conservation...

Importance of wetlands in intensively farmed landscapes to duck production

The Prairie Pothole Region of the northern Great Plains annually hosts 50–80% of North America’s ducks during the breeding season. Accordingly, there are significant government and private funds that go to conservation for the purposes of improving duck production in the region. The Prairie Pothole Region ecosystem has a number of stressors, intensive agriculture being chief among them. The...

Evaluating wetland ecosystem health using real-time nutrient dynamics of ducks

Northern Prairie Wildlife Research Center (NPWRC) leads a collaborative effort, spanning several studies, with the objective of improving techniques to assess the quality of spring migration habitat for ducks. Spring is a critical time in in the life cycle of migratory ducks because during migration they experience peak energetic needs at a time when food resources are often at their scarcest...

Interactions of consolidation drainage and climate on water-level dynamics, wetland productivity, and waterbirds

Northern Prairie Wildlife Research Center (NPWRC) recently completed a project aimed at understanding the impacts of wetland drainage on wetlands that receive drainage water. The biological communities of prairie pothole wetlands evolved in a hydrologically dynamic system due to periodic wet and dry conditions.  NPWRC research indicates that relative to wetlands in undrained landscapes,...

Can wetland water-management influence mercury bioaccumulation in songbirds and ducks at National Wildlife Refuges with mercury problems?

During summer 2017, Northern Prairie Wildlife Research Center (NPWRC) initiated a collaborative research study focused on understanding if water-level management of wetlands at refuges can influence mercury bioaccumulation in wetland-dependent migratory birds.  Birds are susceptible to the effects of mercury and can serve as indicators of contamination in ecosystems. We examined mercury...

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...
