In 1995, Drs. John Sawyer and Todd Keeler-Wolf published A Manual of California Vegetation (MCV). The book was the result of a multi-agency effort to develop a comprehensive and widely accepted classification system for California vegetation. The Manual is a key reference used by ecologists, botanists, and biologists working for many different federal and state government agencies, private businesses, and conservation organizations throughout California. Drs. Sawyer and Keeler-Wolf revised the MCV to make it compatible with the U.S. National Vegetation Classification and to include information on the effects that various disturbances, particularly fire, have on California vegetation. The revision includes an appendix table that summarizes the key biological characteristics associated with fire and other ecosystem processes for the dominant and characteristic species for each vegetation alliance described in the revised Manual. In addition to the appendix table each revised alliance description will include a description of the fire regime either derived from the literature or extrapolated from the disturbance characteristics summarized in the appendix table. For example, for a fire regime the description would include attributes such as frequency, seasonality, size/extent, complexity, intensity, severity, and fire type. To gather the data and information necessary to complete the appendix table of disturbance characteristics and develop the disturbance regime attributes the Information Center for the Environment at University of California Davis conducted a series of five workshops throughout California during 2000 and 2002. The goal of the workshops was to bring together the expertise of a variety of vegetation ecologists, fire ecologists, botanists, fire scientists, biologists, and others who are knowledgeable about how California vegetation responds to disturbance, particularly fire. The first three of the five workshops were funded by JFSP project 98-1-5-02 and completed prior to this project. Information on all five workshops and the deliverables is included here and in the final report for JFSP project 98-1-5-02.
