Forest Health

The term forest health is commonly used to indicate the condition of a particular forest or stand and is in constant flux; after all, the nature of nature is change.

To get a feel for the complexities encountered when trying to define forest health, read Forest Health Conditions in Idaho (PDF), where forest health is defined as “a condition of forest ecosystems that sustains their complexity while providing for human needs.” Choose from the sections below to deepen your understanding and apply your newfound knowledge to your forestlands.

Monitoring Forest Health

Influences that affect forest or stand conditions are either biotic (insects, diseases, invasive plants, poor soil nutrition) or abiotic (adverse weather conditions, pesticide mismanagement).

Forest Insects and Diseases

Forest insects and diseases are natural parts of forest environments. But when there is an outbreak or an introduced problem, losses can be extensive and expensive.

To begin, read What’s Wrong with My Tree? (PDF) to learn more about cause and effect, the diagnostic process and common control methods.

Forest Soils and Nutrition

Commonly overlooked, healthy soils are critical to the success of forestland environments. Explore the world of forest soils and nutrition and learn more about this often ignored, but crucial, component of our forest environments.

Identifying and Controlling Invasive Plants

You may not want them, but you got them. Invasive plants, usually referred to as weeds, are undesirable or troublesome plants that usually grow profusely where they are not wanted. Learn more about them by reading Invasive Species (PDF).

Refine your knowledge about individual invasive plants species, and how to control them, by choosing from the selections below.

  • Idaho’s 67 Noxious Weeds. Idaho has 67 different species of weeds which are designated noxious by state law. These weeds are designated into three levels of concern. The spread of these weeds and the damage they do to Idaho agriculture can be lessened through proper identification and handling.
  • Idaho State Department of Agriculture Noxious Weeds Program. ISDA is responsible for the administration of the State Noxious Weed Law. The State Weed Coordinator and the other program staff provide support, training and organizational assistance to the counties and Cooperative Weed Management Areas throughout the state.
  • Pacific Northwest Weed Management Handbook. This handbook is designed as a quick and ready reference for weed control practices and herbicides used in various cropping systems or sites in Idaho, Oregon and Washington.
