Phase 1 & 2 (2010, 2012): This project developed a sampling design and monitoring protocol for wintering shorebirds in the Central Valley and in the San Francisco Bay Estuary and develop an LCC-specific online shorebird monitoring portal publicly available at the California Avian Data Center. The three objectives in Phase II of this project are: 1) Complete the shorebird monitoring plan for the CA LCC by developing a sampling design and monitoring protocol for wintering shorebirds in coastal southern California and northern Mexico. 2) Develop models to evaluate the influence of habitat factors from multiple spatial scales on shorebird use of San Francisco Bay and managed wetlands in the Sacramento Valley, as a model...
This project assessed the potential effects of climate change on tidal marsh habitats and bird populations, identified priority sites for tidal marsh conservation and restoration, and developed a web-based mapping tool for managers to interactively display and query results. Project results can be found at PRBO’s San Francisco Bay Sea-Level Rise Website
Distribution of Black Oystercatcher habitat in coastal British Columbia showing relative abundance (RA) by season and overall relative importance (RI). RI is based on project region and not on the province as a whole. British Columbia has been collecting coastal resource data in a systematic and synoptic manner since 1979. Resource information is collected using peer-reviewed provincial Resource Information Standards Committee which include standards for data management and analysis
Sources and extent of human disturbance to waterbirds in the UK: an analysis of Wetland Bird Survey data, 1995/96 to 1998/99
Funded project resulted in 6 publications covering various aspects related to shorebird/grassland bird migration, climate and nesting success in the great plains region.
Summary of project, results, and discussion for the study completed by Susan K. Skagen, Amy A. Yackel Adams, Victoria J. Dreitz, Ressa Yale Conrey, Lucy Burris, Gene Albanese, Craig A. Davis and Bradley W. Compton. Summary written by the Great Plains Landscape Conservation Cooperative (GP LCC).
Multiple factor analysis of piping plovers and other beach-dependent species habitat use and population dynamics following storm and human created changes to barrier island habitats within the Fire Island National Seashore (Report)
The goal of this project is to provide a broader ecological understanding of the ways in which the breaches and U.S. Army Corps of Engineers (USACE) breach-fill projects affect piping plover populations, their red fox predators and their invertebrate prey communities. Virginia Tech (VT) compared the dynamics of bird use and invertebrate densities in an open breach area, two filled breach areas, two restoration areas, overwash areas, and other areas. Ultimately VT results will help refine their understanding of the time frame and manner in which piping plover habitat develops and persists.The work described in this report was funded under the Breach Contingency Plan (BCP; USACE 1996), the Fire Island Inlet to Moriches...

The mission of the Migratory Bird Program out of the Southwest Region is to conserve, enhance, restore, and manage Migratory Birds at local, regional, national, and international scales. Our program is made up of Migratory Bird Biologists (i.e., Game, Landbird, Shorebird and Waterbird, and Eagle bios), Permit Biologist, Migratory Bird Habitat Joint Venture Biologists, and collaborating partners.
Stopover use by migrating shorebirds is affected by patch-level characteristics of habitat, but the relative influence of broadscale factors is poorly understood. We conducted surveys of ten 10-km-radius landscapes in north-central Oklahoma from 2007 through 2009 to examine the influence of the amount and composition of wetland habitats and surrounding land cover on shorebird use during migration. We used generalized linear modeling and an information-theoretic framework to identify factors that best explained species richness, total abundance, and abundance of four groups of shorebirds classified by breeding status and migration distance. Total abundance and richness both increased with the area of wetland...
December 1999 classified RADARSAT image depicting winter shorebird habitat in the Willamette Valley, OR
This dataset is one of a collection of three land cover maps of the Willamette Valley of Oregon, USA, depicting 4 habitat classes: wet with <= 50% vegetation cover (class 1), wet with >50% vegetation (class 2), dry with <= 50% vegetation (class 3), dry with >50% vegetation (class 4). Land cover maps were derived by classifying signatures from C-band (5.6 cm wavelength), HH-polarized radar remote sensing (RADARSAT) data collected at a 38 degree incidence angle (8-m resolution). The data are in the form of an ERDAS Imagine image.
Bird sensitivity to spilled oil in coastal environments of Puget Sound and Strait of Juan de Fuca, Washington, USA
This data set contains sensitive biological resource data for wading birds, shorebirds, waterfowl, diving birds, seabirds, raptors, gulls, and terns in Puget Sound and Strait of Juan de Fuca, Washington. Vector polygons in this data set represent locations of bird resting, feeding, migratory staging, and wintering sites. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables designed to be used in conjunction with this spatial data layer. This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Puget Sound and Strait of Juan de Fuca, Washington. ESI data characterize the marine and coastal environments and wildlife...
Land-use change, invasive species, and climate change have dramatically impaired ecosystem function worldwide. Understanding how changes to ecosystems impact species of conservation concern is essential for effective conservation delivery. Of particular importance are environments that provide disproportionate ecosystem services. Throughout the Great Plains Landscape Conservation Cooperative, playas provide disproportionate ecological services, including essential stopover habitat for migratory waterbirds. Anthropogenic change to playa distribution, abundance, and function may impact the ecosystem services provided, with demographic consequences for priority species. We will address partner needs by developing a...
Current and Future Projected Distributions of Wetland-Dependent Birds Across the Great Plains in Response to Climate Change
Playas and other wetlands within the Great Plains Landscape Conservation Cooperative (GPLCC) provide essential habitat for many wetland-dependent vertebrate species and are especially important as migration and wintering areas for waterfowl and shorebirds. Playas in the GPLCC are at risk of unsustainable sediment accumulation, reduced inundation frequency, and declining hydroperiods due to agricultural intensification and a changing climate with expected decreases in annual precipitation, changing precipitation patterns, and higher summer temperatures. We propose to project distribution shifts and/or range reductions of several focal migrating shorebird, waterfowl, and waterbird species in response to climate change,...
The distribution of nesting areas for bird colonies in coastal British Columbia showing relative abundance (RA) by season and overall relative importance (RI). RI is based on project region and not on the province as a whole. Number counts for various species in the colony location are provided. British Columbia has been collecting coastal resource data in a systematic and synoptic manner since 1979. Resource information is collected using peer-reviewed provincial Resource Information Standards Committee which include standards for data management and analysis
Avian influenza in wild waterfowl and shorebirds in the Donana National Park: serological survey using the enzyme-linked immunosorbent assay
Designed by scientists to simplify consistent data collection and management, the iPlover smartphone application gives trained resource managers an easy-to-use platform where they can collect and share data about coastal habitat utilization across a diverse community of field technicians, scientists, and managers. With the click of a button, users can contribute biological and geomorphological data to regional models designed to forecast the habitat outlook for piping plover, and other species that depend upon sandy beach habitat.iPlover app is available for iPhones and Androids on the USGS Mobile Application Directory. The app is free, but users must ask for and receive an approved login to use it. Training is...
