Tools and Technology
We develop advanced technologies such as remote sensing, autonomous vehicles, artificial intelligence, and genetic tools to assess species population and health and improve models that incorporate climate change impacts to predict biodiversity response. These tools help managers develop a more accurate and comprehensive understanding of species population trajectories and distribution shifts.

To control or not to control: response of pollinator communities to invasive plant management
If invasive plants are producing pollen and nectar used by native pollinators, what happens when a manager decides to control the invasive plant? Northern Prairie Wildlife Research Center is addressing this question and has found that pollinators are adept at changing their resource acquisition strategies as abundantly flowering invasive species decline. In addition, it appears that the invasive...
Demographic response of least terns and piping plovers to the 2011 Missouri River Flood
The largest recorded flood event on the Missouri River occurred during 2011. Northern Prairie Wildlife Research Center recently concluded a study that evaluated effects of that flood on least tern and piping plover breeding populations. These federally-listed species nest on riverine sandbars and reservoir shorelines. Since construction of the dams on the Missouri River there have been few floods...
Investigating roadside bias in point-count surveys of grassland passerines
The North American Breeding Bird Survey (BBS) provides much essential information for assessing bird populations, but it is unknown how inherent assumptions of the BBS apply to grassland birds in the Northern Plains. Understanding the effects of these assumptions on our understanding of grassland bird populations is essential given widespread declines of grassland birds as well as recent and...
The effects of management practices on grassland birds
With support from the U.S. Prairie Pothole Joint Venture (PPJV), the U.S. Forest Service, and The Nature Conservancy, Northern Prairie is synthesizing literature on the effects of management practices on grassland bird species. The need for these syntheses was identified by the PPJV, a part of the North American Waterfowl Management Plan, in support of its objective to stabilize or increase...
Developing techniques to census and monitor American white pelicans and other colonial waterbirds at Chase Lake National Wildlife Refuge in North Dakota
Monitoring colonial waterbirds is essential to detect and to provide insights about changes in waterbird distribution and abundance. For colonial waterbirds, major population fluctuations often go undetected because surveys are not conducted regularly, inventory methods are inconsistent, or estimates have unknown reliability. The waterbird colony at Chase Lake National Wildlife Refuge in North...
Support to Fish and Wildlife Service and Prairie Pothole Joint Venture for monitoring and management of migratory bird populations
Sound management of migratory bird breeding populations in the U.S. Prairie Pothole Region hinges on effective monitoring programs and comprehensive analyses of long-term survey data. To this end, Northern Prairie provides support to the U.S. Fish and Wildlife Service in several important areas. The Four-Square-Mile Breeding Duck and Habitat Survey was developed by Northern Prairie in the mid...
Studying Immune Responses in the American Kestrel (Falco sparverius)
The objectives of this study are to (1) investigate whether the immune system will respond to chemical stressors, such as new flame retardant compounds, and (2) determine if such chemical stressors influence white blood cells (WBC) responses after exposure to a viral pathogen mimicking bird flu.
Joint Ecosystem Modeling: Cape Sable Seaside Sparrow Marl Prairie Indicator
Marl prairie is the most diverse freshwater vegetation community in the Greater Everglades and provides the only suitable habitat for the federally endangered Cape Sable seaside sparrow (CSSS; Ammodramus maritimus mirabilis ).
Joint Ecosystem Modeling: EverSnail
EverSnail, developed in collaboration with the University of West Florida, is an age- and size-structured spatially-explicit landscape model of native apple snails ( Pomacea paludosa ).
Joint Ecosystem Modeling: Alligator Production Probability Model
Because the American alligator ( Alligator mississippiensis ) is a keystone species of the Everglades ecosystem, managers need a way to quantitatively assess the effects of alternative restoration scenarios on alligators.
Structured Decision Making
The biggest natural resource management challenges include competing views of the value and uses of those resources in society. Patuxent scientists develop methods to manage resources given those competing views under a “structured decision making” (SDM) framework. Our scientists both practice and train others in key SDM skills, such as model development and monitoring design.
Decision Support Systems
A Decision Support System (DSS) can be defined in many ways. The working definition the Upper Midwest Environmental Sciences Center (UMESC) uses is, "A spatially based computer application or data that assists a researcher or manager in making decisions ." This is quite a broad definition and it needs to be, as the possibilities for types of DSS are limited only by the user group and the developer...
