Defoliation event on Kodiak National Wildlife Refuge

Bill Pyle, Supervisory Wildlife Biologist at Kodiak National Wildlife Refuge, sent photos and specimens from a large defoliation event on deciduous trees and shrubs on western Kodiak Island.

He wrote, “this event apparently encompasses tens of thousands of acres of mixed deciduous forest and woodland of north and east aspect mountain slopes between sea level and treeline limit (~1,800′ elevation span) of western Kodiak Island. Primary tree species affected include Sitka alder, Kenai birch, and black cottonwood.

[The photos] generally characterize the visual aspect of the infestation adjacent to south shore of mid Zachar Bay. Similarly extensive infestations have been observed on north and east slopes of other bays and headlands of western Kodiak Island.”

New Publication: Characterizing spatial distributions of insect pests across Alaskan forested landscape: a case study using aspen leaf miner (Phyllocnistis populiella Chambers)

In this article appearing online in the Journal of Sustainable Forestry, long-term temperature and precipitation data were shown to be important ecological drivers in determining the distribution of aspen leaf minor (Phyllocnistis populiella Chambers) and the aspen (Populus tremuloides Michx.) host in the state of Alaska.
