Abstract

• Tree defoliation (from insect parasites) is not abnormal in the densely forested areas of Alaska, but large outbreak events in recent years have led to cause for alarm.

• To better understand the factors affecting defoliation, we used remote sensing and GIS (geospatial information system) technologies to look at mortality spatial patterns across Hemlock and Spruce forests in southeast Alaska.

• Elevation and proximity to water as well as other factors were considered in determining the impacts of outbreak events due to evidence that changes in landscape can alter parasitism behaviors (Roland & Taylor, 1997).
