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.”
