Title: Ecosystem Effects and Propagation of the Biscuit Fire Across the Large-Scale Plots of the Long-Term Ecosystem Productivity Experiment

Project Proposal Abstract: When the Biscuit fire burned through the experimental plots established by the long- term ecosystem productivity (LTEP) program, new opportunities emerged to study the effects of moderate and severe fire on forest ecosystems, the effect of different forest conditions on propagation of the fire through the plots, and the interactions of initial conditions and fire through time. What this proposal offers, that perhaps no one else can, is a wide range of conditions, created by the experiment, with exacting, georeferenced pre-fire detail on soils, vegetation, and other conditions, and an extensive sample archive. We expect to have strong inference to many parts of the managed areas in the western Siskiyou National Forest because of the pre-fire data, and because we have control blocks spared by the fire. Objectives are to quantify: changes in pre- and post-fire conditions, thought to influence biodiversity and productivity, and spatial variation in fire intensity and severity and erosion across the 15- to 20-acre plots. We will also evaluate: fire intensity and severity as a function of pre-fire vegetation and woody debris conditions created by the LTEP treatments, and associated successional responses including invasive species. Our pre-existing photo archives will allow us to evaluate public perceptions to the fire as well. Many opportunities exist to link this study to the fire surrogates study (see Mclvar letter), to administrative studies by the Forest (see McHugh letter), and possibly to the proposed large-scale assessments and remeasurements of inventory plots. Technology transfer is assured through the LTEP program web page, direct connection to managers on the Siskiyous, participation in the Joint Fire Science workshops, and various publications.
