Wittwer D. 2003. Forest health protection report, forest insect and disease conditions in Alaska - 2002. U.S. Department of Agriculture (USDA), Forest Service General Technical Report. R10-TP-113. US Forest Service, Forest Health Protection; Alaska Department of Natural Resources. Anchorage, AK
Aerial detection mapping is conducted annually to document the location and extent of active forest insect and disease damage. Each of these surveys (southease Alaska, interior Alaska, and south-central Alaska) covers approximately one-fifth of the forested land in the State. Twenty-four million acres throughout Alaska were surveyed in 2002. Insect and disease activity, mapped via aerial surveys, nearly doubled in 2002 over 2001 levels (484,626 acres vs 266,299 acres). This significant increase was due to an outbreak of aspen leaf miner near Fort Yukon, in interior Alaska, totalling 300,000 acres.
