The US Prairie Pothole Region (PPR) has experienced some of the highest rates of grassland loss in North America over a time that coincides with dramatic declines in grassland songbird populations yet increasing abundance of most grassland-nesting duck species except for northern pintail. To provide more insight into this contradiction, we propose to capitalize on long-term databases to evaluate how a key population driver nest survival for North American ducks has responded to system changes in the region including landscape and climatic factors. Outcomes of these analyses will contribute to testing primary conservation planning assumptions for the PPJV a vital component of the PPJV Strategic Habitat Conservation...

These data represent reproductive ecology characteristics for 4 species of mature female turtles captured at Elephant Butte Reservoir on the Rio Grande River in New Mexico, during two field survey periods in June 2012 and 2013. Data were collected on female reproductive ecology including clutch size, egg size, timing of egg production, and the percentage of reproductive females using X-radiography. The purpose of these data are to add to the deficient information on the reproductive ecology of four turtle species at the Elephant Butte Reservoir on the Rio Grande and Black River in New Mexico. Data contained in this worksheet were analyzed to determine clutch and egg sizes for four native species of turtles (Apalone...
The mottled duck, a focal species for the Gulf Coast Prairie Landscape Conservation Cooperative, is one of only a few duck species adapted to breeding in southern marshes. A major part of its population spends its entire life cycle within a relatively small coastal area in eastern Texas and western Louisiana. This is a thriving part of the Mississippi and Central Flyways, two of four major waterfowl migration routes in North America. In recent years, the mottled duck’s habitat and surrounding areas have been compromised by urbanization, agricultural development, and changes to the area’s hydrology affecting coastal wetlands. The latter threat includes the ramifications of climate change, such as sea level rise and...

Distribution of Alcid 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
WFowl01Vol1 depicts known waterfowl habitat areas in twenty-six environmentally sensitive areas along the Arctic, Western and Southwestern coast of Alaska. This data are a combination of duck and geese data digitized from mylar original maps from the Alaska Habitat Management Guides (1985) and updated bulelines from area biologists (1997 and 2001). Data for the following categories were captured: Known spring concentrations - areas where concentrations of one or more species of waterfowl have been observed during spring migration for more than one year. Known nesting concentrations - areas where concentrations of one or more species of nesting waterfowl have been observed during more than one year. Known fall concentations...
Robust assessments of nesting periods and durations for many grassland-nesting birds in the Great Plains are lacking. The timing of management practices (e.g., grazing, haying, mowing, burning) will invariably have different benefits or impacts to different guilds of birds. Our goal is to inform decisions about timing of management practices with research to provide an improved quantification and understanding of contemporary nesting season patterns for grassland birds. Results from this project could aid program managers through improved assessments of tradeoffs from the timing of management actions for various priority birds in the Great Plains.

Includes wintering and nesting areas of Western Snowy Plover, Bank Swallow closure areas, and Lessingia recovery areas. National Parks Service (NPS) identifies several special management areas within the study area, including a portion of Ocean Beach that is managed as wintering habitat for the western snowy plover; San Francisco lessingia recovery areas near Baker Beach and Fort Funston (NPS, 2002), and; a seasonal bank swallow closure area (NPS, 2010) at Fort Funston. This dataset also includes Pinniped haul-out areas describe by NOAA (2007) to include single-event haul-out locations and areas with continual Pinniped use, and citizen-monitored snowy plover wintering areas at Linda Mar Beach (Pacifica Riptide,...
The British Columbia Marine Conservation Analysis (BCMCA) is a collaborative project assembling and analyzing spatial information about Canada's Pacific Ocean. The overall goal of the BCMCA is to identify marine areas of high conservation value and marine areas important to human use. Results of the project are intended to inform and help advance marine planning initiatives in BC by providing collaborative, peer-reviewed scientific analyses based on the best ecological and human use spatial data at scales relevant to a BC coast-wide analysis.
