Title: Pre-Fire Fuel Manipulation Impacts on Alien Plant Invasion of Wildlands

Project Proposal Abstract: This proposal addresses the impacts of fuel breaks or defensible fuel reduction zones on invasion of alien plant species into wildland areas representing diverse fuel types, including shrublands, woodlands and conifer forests. It will investigate this potential impact on Federal (BLM, NPS, and USFS), state (CDF) and local jurisdictions throughout California and has multi-agency cooperation and support. There are three objectives: 1) To inventory current floristic composition of fuel breaks in southern California, central coast, north coast and the Sierra Nevada and relate patterns of alien plant distribution to fuel break parameters, including construction age, past maintenance, vegetation modification treatment, proximity to roads, and other environmental variables. 2) Intensively sample belt transects from fuel breaks into surrounding vegetation to determine the extent to which fuel breaks may act as source populations for the invasion of wildland areas; this sampling will focus heavily on areas that have experienced fires within the last decade, as this is likely to be the time when ecosystems are most sensitive to the invasion process. 3) To educate resource managers on the potential problems of invasive plants, both in terms of displacing native vegetation and altering fire regimes, and on how fuel manipulations may be planned to minimize these impacts on natural landscapes.
