Much later in the life of a stand, overstory trees die in a spatially patchy pattern while some of the younger trees in the understory begin to grow into the overstory (Oliver and Larson 1996). We measured diameter at root collar (DRC) for all live and dead trees and total height for all live and standing dead trees. Plants less than two meters in height were considered part of the understory and those greater than two meters the overstory. Fractal dimensions of both canopy and buffaloberry were estimated and then related using box-counting methods to evaluate spatial heterogeneity based on patch distribution and abundance. In 2002, we measured overstory, understory, and surface fuels characteristics on each plot. Vine abundance, snag density, and other factors which have species specific value are also acquired.
