Habitat fragmentation and degradation are considered to be a leading causes of long-term population declines of Northern Bobwhites and many other species of grassland birds, such as Eastern Meadowlark. Research is needed to understand the factors causing habitat loss and fragmentation and to identify the areas that are high-probability candidates for successful restoration so that optimal decisions can be made. For example, uncertainty exists regarding the impacts of energy development activities or climate change that affect significant portions of wildlife populations in the GCP LCC. Furthermore, changing land ownership coupled with woody shrub and exotic grass encroachment have reduced the amount and quality...

Loss and fragmentation of grassland habitat can influence populations of the animal communities dependent upon this ecosystem. Grassland birds have faced notable declines in some areas of their range, potentially a result of changes to suitable habitat. Managing populations of grassland birds requires an understanding of the effects of habitat loss and fragmentation at a local and regional scale. We studied two grassland-dependent bird species, Eastern Meadowlarks (Sturnella magna) and Northern Bobwhites (Colinus virginianus), in an area of recent explosive growth in oil and gas related development. First, we quantified habitat lossand fragmentation of grassland habitat using remotely sensed datasets at multiple...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
