Native Forest Insects. Tens of thousands of species of insects are found in our forests and rangelands, and many play an important role in pollinating plants, recycling nutrients, decomposing vegetation, and providing food for wildlife.

They also occasionally can kill trees and impact forest health. Aerial forest health surveys in Alaska are a cooperative effort between USDA Forest Service – Forest Health Protection and the Alaska Division of Forestry. Surveys take place in July and generally cover around 32 million acres annually.

From the air, surveyors can identify damage caused by forest insects, diseases, and abiotic stressors. According to “Insects and Disease of Alaskan Forests (Edward H.
