Title: Jeffrey Pine-Mixed Conifer Fire History and Forest Structure With and Without Fire Suppression and Harvesting

Project Proposal Abstract: High severity wildfires are common in pine forests of the western United States. Many have suggested this is primarily due to changes in stand structures and composition from past logging and systematic fire suppression of the last century. There is currently debate on appropriate target conditions for fire hazard reduction and forest restoration. This is due to the lack of unmanaged forests that could serve as references in the western US. The pine-dominated, mixed conifer forests of the Sierra San Pedro Martir (SSPM), Mexico, have not experienced logging and systematic fire suppression. The SSPM is unique within the California floristic province in that its forests are still regularly influenced by fires similar to those that once occurred throughout the western United States. The mixed conifer forests of the SSPM can provide information on reference conditions for forests that prehistorically experienced frequent, low to moderate intensity fires. This information could be used to help develop target stand conditions for reducing the fire hazard in large portions of California and Nevada mixed conifer forests. The objectives of this project are to compare climate, fire history, and stand structures of coniferous forests of the Sierra San Pedro Martir with similar forests of the Sierra Nevada. (This proposal requests funds for work in the eastern Sierra Nevada, matching funds will be used for the work in the SSPM).
