Unacceptable damage
from insects and disease is a particular issue in eastern
Oregon and Washington forests and in south-central Alaska.
Our team members, located in Anchorage and Juneau, Alaska,
and Corvallis, Oregon, focus on studies that design and test
options for managing forests to be resistant to outbreak
situations as well as mitigating adverse affects during outbreaks.
We emphasize methods to detect, monitor, predict, model,
and mitigate insects and diseases, emphasizing semiochemical
(behavioral chemical) technologies; and we develop understanding
and management approaches to enhance or conserve the desirable
effects of insects and tree diseases in forest ecosystems.

- Develop pheromones and phytochemicals to detect and mitigate
insects and disease, including at the landscape scale.
- Develop silvicultural approaches to regulate effects of diseases and insects
on forest structure and composition.
- Determine how to monitor effects of disturbance on abundance, function, and
diversity of arthropods.
- Determine the ecological roles of root diseases and develop strategies to
encourage their desired effects in ecosystem management.
- Determine roles of heart rot, dwarf mistletoe, and other organisms as disturbance
agents in old-growth forests of southeast Alaska.
- Determine the epidemiology of yellow-cedar decline in southeast Alaska and
evaluate the salvage value of killed trees.
