Current Research

Acquire new knowledge for the maintenance or restoration of wildlife species as viable and functional components of interior PNW forest ecosystems. The applied focus is on research and development of adaptive ecosystem management and conservation strategies that sustain key habitats and species (e.g. late-successional forest and the northern spotted owl).

Research Interests

• Small mammal and avian population and habitat ecology in dry forests. • Developing and testing dry forest restoration prescriptions that address multiple ecological objectives. • Development of decision support and planning models for fuel, fire, wildlife, and old forest management. • Habitat ecology of ungulate species. • Collaboration with Indian scientists and forest managers on ecosystem management of forests and grasslands in India.

Why This Research is Important

Dry forests in interior western North America have experienced significant change as a result of human activities. In particular, fire disturbance regimes have been altered resulting in changed forest pattern and process, particularly, increasing occurrence and extent of high-severity wildfire. Restoration management has focused on reducing fuels and restoring forest pattern and process. In the Eastern Cascade Range, conservation of the threatened Northern Spotted Owl, its ecological web, and associated old forest has been a driver of forest management during the last nearly 20 years; but, those efforts often seem incompatible with forest restoration and generate conflict. Basic and applied wildlife research is critical for integrating wildlife issues with dry forest restoration to reduce fuels, alter fire behavior, and restore forest structure.
