Title: A Comprehensive Guide to Fuels Management Practices for Ponderosa Pine/Mixed Conifer Forests

Project Proposal Abstract: We propose an 18-month project to develop an integrated synthesis that provides forestland managers with comprehensive, up-to-date knowledge on ecological values and options for management of harzardous fuels within ponderosa pine / mixed conifer (PP/MC) forests. PP/MC forests occur throughout the interior West, the Sierra Nevada, Cascade Range, Klamath Mountains, and Pacific Coast. Within this wide range of biophysical settings, PP/MC forests are associated with historically complex fire regimes. Since the 1800s, fire exclusion, animal grazing, timber harvesting, widespread human settlement, and climate change have contributed to an altering of these forests. Stand structure, species composition, fuel arrangement, fuel mass, and forest succession have all been affected and have collectively resulted in altered fire regimes. Substantial documentation exists on fire ecology and appropriate hazardous fuel management practices for pure ponderosa pine forests. The PP/MC forest type, however, is less well understood, and is characterized by greater productivity, complex vertical and spatial structure, diverse species assemblages, and varied fire regimes. Fuel management practices borrowed from the pure ponderosa type may be inappropriate for the different conditions presented by the PP/MC forest type. This project will be implemented by an interdisciplinary team (ecology, silviculture, fuels management, and forest operations) comprised of reserachers and experts who have been extensively involved in the development of fuels treatments, analysis of fuels treatment effectiveness and biodiversity implications, and linking forest structure to fire behavior and hazard. We will perform a thorough scientific literature search to integrate up-to-date knowledge associated with fuels treatment within PP/MC forests. Land managers input and feedbacks are another primary component of the project that will be incorporated to better understand their needs and challenges in fuels management. This project will combine researchers, collaborators, and land managers in face-to-face meetings and four regional workshops. At the end of the project we will deliver a comprehensive handbook for fuels treatment and provide managers with web-based access to our project objectives, methods, timeline, links and summaries of the deliverables/results.
