I am a Research Wildlife Biologist at the U.S. Geological Survey, Forest and Rangeland Ecosystem Science Center. My research focuses on providing information to support management and conservation of native wildlife species and their habitats.
My research interests include forest and wildlife ecology, conservation of biodiversity in managed forests, conservation and management of native Willamette Valley ecosystems, and riparian songbird response to floodplain restoration. Much of my work has focused on the biologically and economically important conifer forests of the PNW that are intensively managed for multiple uses and represent a large area in public domain. My research projects are designed to increase understanding of how conifer forest management affects biodiversity across a range of spatial and temporal scales, and to provide science-based information that can be directly applied in an adaptive management framework.

In this episode we sit down with USGS wildlife biologist Joan Hagar and discuss her recent study on songbirds in the Pacific Northwest. New research indicates a possible relationship between reductions in the abundance of some species of songbird and reductions in the amount of deciduous trees in evergreen forests.
