Disturbance And Forest Health In Oregon And Washington

The scope and intensity of disturbance by such agents as fire, insects, diseases, air pollution, and weather in Pacific Northwest forests suggests that forest health has declined in recent years in many areas. The most significant disturbances and causes of tree mortality or decline in Oregon and Washington are presented and illustrated. This report discusses the interrelations of native trees and suggests some solutions for reducing the severity of disturbance. One chapter reports on a forest health monitoring pilot project.

Excerpt from Disturbance and Forest Health in Oregon and Washington Citizens, forest owners, and resource managers must all be come active to solve forest health problems in Oregon and Washington. Without cooperation and interaction among groups with diverse and opposing viewpoints, future needs and desires for products and services from regional forests will not be met. East of the Cascades, forest fuel reduction, thinning over stocked stands, and changing species are needed to reduce the risks of uncontrollable, stand-replacing wildfires and widespread insect outbreaks. West of the Cascades, the continued introduction of exotic insects, diseases, and plants threaten the existence of native forests and, without continual vigilance, chances of establish ment and spread are much greater. Air pollution, unless controlled and reduced in the Puget Sound area and the Willamette Valley, will affect increasing numbers of forest species, influencing their ability to grow and reproduce. On both sides of the Cascades, the incidence and severity of many native insects and diseases is closely linked to forest management. Awareness of the effects of different manage ment activities on insects and diseases is essential to achieve desired forest conditions. Forest management, forest health monitoring, research, and public education are the tools needed to create and main tain the forests that are so important to the people of Oregon and Washington.
