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...

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...

Grassland birds throughout the United States have exhibited significant declines in the last three decades indicated no grassland bird species in the Upper Midwest were increasing in abundance. Continental and regional population declines are mirrored in Wisconsin with species like Henslow’s Sparrow, Grasshopper Sparrow, Eastern Meadowlark and others declining by 50 – 90% since 1970. Conservation groups, state and federal agencies within the Upper Midwest have long recognized these declines and have taken action, yet despite the value of these conservation actions, none of the grassland birds have halted their population declines or returned to population sizes of the 1970s. Within the conservation community there...
