Sierra Nevada avian diversity
In partnership with Dr. Zach Peery at UW-Madison and the U.S. Forest Service, we conduct acoustic surveys across the entire Sierra Nevada. The project encompasses over 18,000 km2, generates 1,000,000 hours of audio annually, and yields data on over 100 species of bird.
Yosemite Toad demography
The Yosemite Toad is federally endangered, but little is known about its population status. I am developing landscape-scale population demography surveys, which could help understand and thus arrest population declines.
As wolf populations recover in the western U.S. and elsewhere, the potential for conservation conflicts grows. We are using traditional passive acoustic surveys and real-time acoustic monitoring to study the spatiotemporal dynamics and demography of wolves, with the aim of improving the quality and efficiency of wolf management.
Spotted Owl conservation
Spotted Owl conservation is a driving force behind much of what we do. This includes monitoring population trends and responses to habitat change and supporting an unprecedented landscape-scale removal of an invasive competitor, the Barred Owl.
