Fire And Post Fire Management

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…show more content…
Both hypothesizes can be combined to one; that if an area is high-severity, high pre-fire density, and logged (HHL) it will have a higher density than the high-severity, low pre-fire density, and logged (HLL). Methods The lands that burned during this fire were mainly comprised of a mixed-conifer forest. The main tree species found before and after the fire are Douglas- fir, grand fir, Pinus ponderosa (ponderosa pine; PIPO), and Pinus contorta (lodgepole pine; PICO). Other species found include other varieties of spruce, pine, and larch. In some areas of the site a rich understory has formed or still exists; these were dominated by Salix scouleriana (Scouler’s willow; SASC) with a limited variety of forbs present beneath the shrubs. Post-fire management tactics included salvage logging and grass seeding. This seeding of native grasses was spread across burned areas in combination with mulch in the form of agriculture straw as well as shredded wood strips (Robichaud, 2009). In order to collect data, protocol was followed as described in by P. Morgan and P. Higueraa’s (YEAR)School Fire Field Trip Handout and Assignment packet. In September 2015 the FOR 326 class from University of Idaho followed this protocol to find and collect data from 32 sites on two different days. To determine site locations, trip leaders took each group to a random pre-determined area that corresponded with fire
