Use of Structured Decision Making to Optimize Salt Marsh Management Decisions at Northeastern National Wildlife Refuges

US Fish and Wildlife Service completed a regional assessment of salt marsh integrity (SMI) on 15 National Wildlife Refuges/Refuge Complexes in the northeastern US. Developed within a structured decision making (SDM) framework, the SMI assessment provides essential baseline data on salt marsh condition relative to regional management objectives. These data now provide the basis for applying the SDM...

Monitoring Birds in National Parks of the Gulf Coast Network

The Challenge: Avian monitoring within the Gulf Coast Network of the National Park Service is challenged to provide valid quantitative data on bird populations within park boundaries with limited financial input. Thus, citizen science (volunteer) bird monitoring has been proposed to achieve reliable estimates of bird populations and to assess the effects of habitat change and temporal dynamics of...

Evaluating the Design of the Waterfowl Breeding Population and Habitat Survey

The Waterfowl Breeding Population and Habitat Survey (WBPHS) is a primary source of waterfowl population status and trend information for management of ducks in North America. The survey has not been reviewed in several decades, and since the last review new analysis approaches and information needs have created a need to reassess the design, scope of inference, and analysis of the survey to...

Using Advanced Technology to Enhance Research at the Patuxent Wildlife Research Center (PWRC) - a Public-Private Partnership

This project is focused on exploring the use of new technology to collect data on colonially nesting waterbird species in ways that reduce disturbance, improve data accuracy, or allow for the examination of previously unanswerable questions.

North American Breeding Bird Survey

The North American Breeding Bird Survey (BBS) is the primary source for critical quantitative data to evaluate the status of continental bird species, keeping common birds common and helping fuel a $75 billion wildlife watching industry. Each year thousands of citizen scientists skilled in avian identification collect data on BBS routes throughout North America allowing us to better understand...

Population Change and Abundance of Black Ducks and Mallards in Eastern North America

The boreal forest in the northeastern United States and eastern Canada contains most of the breeding range of the American black duck (Anas rubripes). We collaborate with scientists from the U. S. Fish and Wildlife Service to design and analyze waterfowl surveys in this large and often inaccessible area.

Hierarchical Models for Estimation of Population Parameters

The Challenge: Much of wildlife research consists of the description of variation in data. Some of the variation results from spatial and temporal change in populations, while some results from biologically irrelevant sampling variation induced by the process of data collection. Distinguishing relevant from irrelevant variation is the first task of statistical analysis, but the job does not end...

Development of Computer Software for the Analysis of Animal Population Parameters

Biologists at USGS Patuxent, as well as cooperating agencies are constantly looking for new ways of answering questions about the status of animal populations and how animal populations change over time. To address these questions, data are collected on captures and or sightings of animals which can be used to estimate parameters which affect the population using legacy software. Over time, new...

Integrating Habitat and Harvest Management for Northern Pintails

The Challenge: Several blue-ribbon panels have challenged the waterfowl management world to recognize the linkages between the two primary management frameworks: harvest management under the Migratory Bird Treaty Act, and habitat management under the North American Waterfowl Management Plan. Because these two frameworks seek to manage the same populations, there needs to be better coordination, in...

Breeding Bird Atlas Explorer

The Challenge: A Breeding Bird Atlas (BBA) is a widespread survey method that provides distribution maps for all bird species that nest in a specific state or province. Hundreds of participants fan out over several seasons to their assigned blocks on a systematic survey grid; they search for breeding evidence such as a male/female pair of a species on a branch (“possibly breeding”), or an adult...
