Recent Research/Educational Projects:
The Effects of Conventional and Unconventional Oil and Gas Development on Forest Habitat and Birds – Energy exploration and development for oil and gas includes both shallow (conventional wells) and also deep horizontal wells associated with shale gas development. Shale gas development is relatively new to Pennsylvania and is occurring at a rapid rate within forest habitat in North Central Pennsylvania. My students and I have been researching the effects of shale gas development on forest habitat and birds. Our studies are providing baseline data on conditions at the onset of shale development and initial changes that are occurring. We are examining the impact energy extraction and development is having on Pennsylvania birds in order to determine community changes, and to determine which species benefit and which are most vulnerable. We are also initiating studies to examine potential impacts to forest salamanders and frogs.
Avian Response to Pennsylvania’s Conservation Reserve Enhancement Program - The Pennsylvania Conservation Reserve Enhancement Program (CREP) was initiated in 2000, and within four years 40,000 ha of conservation grasslands were established in Southern Pennsylvania. My students and I have worked with researchers at the Pennsylvania Game Commission to examine the effects of CREP on farmland and grassland bird populations during the 10 years since the program began. Results are being used to target areas for enrollment and modify management guidelines.
Factors Influencing Habitat Quality and Productivity of Pennsylvania's Forest Songbirds In forest habitat, a variety of factors including habitat fragmentation, acidic deposition and introduced pests like the hemlock Woolly Adeligid affect habitat quality and ultimately breeding success. My students and I are using field-based observational and experimental studies to determine factors influencing habitat quality and reproductive success. Research results will be used to develop management guidelines and conservation priorities.
