Introduction In 2005, Pomeroy, Washington experienced a storm with multiple lightning strikes causing ignitions that started a large scale fire. This was designated as the School Fire Complex - the location of our study (Figure 1). The fire burned for fourteen days, consuming 21,000 hectares of land, including 87 buildings and 56% of the Umatilla National Forest Land. Almost half the federally owned land had been previously thinned for fire management (MODIS 2005). During the 2015 Fire Ecology and Management class (FOR 326) field trip to the School Fire Complex, the class surveyed a series of sites in order to create a research project to obtain a better understanding of fire and post-fire management. The goal of this research is to answer 2 questions: It was at this site that the question post-fire management effects on species was created. Specifically, how does the burn severity and post-fire logging influence the density of tree seedlings of Abies grandis (grand fir; ABGR) and Pseudotsuga menizesii (Douglas- fir; PSME)? Also, does the pre-fire density factor intocorrelate with the post-fire regeneration density? In a preliminary visual assessment, each site seemed to have its own set of characteristics leading to two primary hypotheses. The high-severity and logged (HHL) sites will have a greater density of the two species’ tree seedlings than a high-severity and unlogged (HHU) site. In addition, it is hypothesized that the areas of low pre-fire density (HLL, MLL, LLLL)
