Prairies were once widespread across North America, but are now one of the most endangered and least protected ecosystems in the world. Agriculture and residential development have reduced once extensive prairies into a patchwork of remnant prairies and “surrogate” grasslands (e.g., hayfields, planted pastures). Grassland ecosystems and many grassland-dependent birds are also particularly vulnerable to rapid shifts in climate and associated changes in drought and extreme weather. The Central Flyway is a vast bird migration route that comprises more than half of the continental U.S., and extends from Central America to Canada, and harbors the greatest diversity of grassland birds in North America. Throughout this...

Unconventional oil development in the Bakken shale region has increased rapidly as a result of new technologies. This region also supports a particularly high density and diversity of grassland bird species, which are declining across North America. We examined grassland bird response to unconventional oil extraction sites (i.e. developed with hydraulic fracturing and horizontal drilling) and associated roads in North Dakota. Our goal was to quantify the amount of habitat that was indirectly degraded by oil development, as evidenced by patterns of avoidance by birds. Grassland birds avoided areas within 149 m of roads (95% CI: 4 – 294 m), 267 m of single-bore well pads (95% CI: 157 – 377 m), and 150 m of multi-bore...

This region also supports a particularly high density and diversity of grassland bird species,which are declining across North America.

Our goal was to quantify the amount of habitat that was indirectly degraded by oil development,as evidenced by patterns of avoidance by birds. Grassland birds avoided areas within 150 m of roads(95% CI: 87–214 m), 267 m of single-bore well pads (95% CI: 157–378 m),...

Oil and gas development in North Dakota is occurring at a rapid rate, and managers and biologists are ill-equipped to address and minimize damage from oil development and related activities on fish and wildlife habitat. This project aims to gather information on impacts to grassland birds from oil and gas development to better inform conservation managers.The 2012 pilot season was a success. Bird surveys were conducted at 18 oil wells and four control sites. Preliminary findings showed reduced densities of grassland birds near wells compared with away from wells, but the effect varied among species. Continuing work will strengthen inferences as well as attempt to assess effects on uncommon species such as Baird’s...

Wind power is a promising clean energy technology that has grown rapidly in recent years (EIA 2013). In spite of its environmentally friendly reputation, industrial wind energy generation can have serious impacts on wildlife. Bat and bird collision fatality rates have been alarmingly high at some wind farms. Proper siting of wind facilities may help minimize collision impacts as the wind energy industry continues to grow. Bat and bird fatality rates vary greatly among sites; however, there is no reliable method for assessing collision risk prior to development. My goal was to develop a method for predicting fatality rates based on nocturnal activity patterns measured by ground-level recording of bat and bird calls....

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.
