Glossary
For the purpose of the 2003 Forestry Program for Oregon, the Board of Forestry uses the following key definitions:

“Active management” means the application of practices through planning and design, over time and across the landscape, to achieve site-specific forest resource goals. Active management uses an integrated, science-based approach that promotes the compatibility of most forest uses and resources over time and across the landscape. “Active management” should not be equated with “intensive timber management.” Instead, it refers to taking proactive steps to achieve whatever management objectives have been established for a forest site. [Based on OAR 629-035-000 (1).]

“Aggressive fire suppression” means the proactive and immediate application of activities necessary to extinguish undesired forest fires, beginning with fire detection and continuing until fires are completely controlled and extinguished.

“Best management practices” means a combination of practices that are determined to be the most effective and practical means (considering current technology, economics, and institutional frameworks) of controlling water pollution at levels compatible with water and environmental quality goals.

“Biological diversity” means the presence of various kinds and types of living organisms. Maintaining biological diversity requires maintaining a diversity of habitats and ecological processes at various spatial scales, from entire landscapes to specific localized habitats. It also includes maintaining populations of individual species and maintaining the genetic diversity of these species.

“Conservation” means management of a renewable natural resource with the objective of sustaining its productivity in perpetuity while providing for sustainable human uses.

“Ecosystem” means a spatially defined, relatively homogenous area that includes all interacting organisms and components of the abiotic environment within its boundaries.

“Enhance” means to make greater in value.

“Forest health” means a healthy, vital forest landscape that maintains its functions, diversity, and resiliency within the context of natural disturbances and that is capable of providing people with the array of values, uses, and products desired now and in the future. Forests are “unhealthy” when potential disturbances, such as fire or pest outbreaks, are unusually frequent, severe, or widespread and when the desired outputs such as wood fiber, special forest products, and recreational opportunities cannot be provided or sustained.

“Maintain” means to keep in an existing state.

“Protect” means to cover or shield from injury or destruction.

“Sustainable forest management” means forest resources are used, developed, and protected at a rate and in a manner that enables people to meet their current environmental, economic, and social needs, and also provides that future generations can meet their own needs. [Based on ORS 184.421 (4).]
