My current research focuses on community responses to fire and fuel reduction treatments in Washington and Oregon, with projects examining fungal, avian, small mammal, and arthropod communities in burns of different severity and age. I am also involved with research on the threatened marbled murrelet and studies of its spatial ecology, productivity, and diet in Washington State. To accomplish research objectives I collaborate with researchers across many disciplines and employ a wide range of field techniques, including large-scale telemetry tracking and habitat modeling projects, to fine-scale eDNA sampling and camera trap studies
- Applying behavioral ecology to problems in conservation and management
- Wildlife responses to fire, particularly comparisons of prescribed versus wildfire burns
- Management and conservation of threatened species
- Disturbance and landscape ecology
My past research has included studies of songbird communities in the northwestern U.S., small mammal abundance in subalpine forests in Idaho, Washington, and Montana, seed dispersal in whitebark pine, cone production impacts on wildlife community composition, habitat selection Clark's nutcracker, and space use in white-headed woodpecker in managed forests.
Why This Research is Important
Research indicates that we are living through an era of increasingly large and severe wildfires in western North America. In recent years, fires have dominated national news headlines and climate change is expected to increase the severity and extent of these fires. Throughout the U.S. managers are faced with challenges of improving the resiliency of forests to such large-scale disturbance events while providing for natural ecosystem function. Within this context, I am interested in wildlife responses to fire. Although many species benefit from fire we lack information on how to best provide habitat for fire-adapted species while balancing the public’s concern for preserving property and other human commodities. Over the last several decades, many untested hypotheses have developed in this field – for example, many cavity-dependent species are attracted to post-fire habitats but we do not know the extent to which species are responding to increases in arthropod food, reductions in nest predator abundance, or changes in fungal community composition that accelerate wood decay. As such, I conduct comparative studies of arthropod, avian, mammalian, and fungal communities in post-fire habitats.
