Abstract
Yellow-cedar is a culturally, economically, and ecologically important tree in coastal Alaska that has been experiencing a widespread mortality known as yellow-cedar decline for about 100 years. Mapping during annual aerial detection surveys has identified nearly the entire geographical distribution of the problem, which totals over 500,000 acres in Alaska (Lamb and Wurtz 2009) and additional acreage in adjacent British Columbia (Hennon and others 2005). This broad-scale approach to detection has been useful in determining the general occurrence of this forest decline, but mapping from aircraft produces large polygons that are too coarse to evaluate some associated landscape features. Examining yellow-cedar decline at a finer spatial scale is needed to test associations of factors such as slope, elevation, and aspect.
