    A taxonomic Vegetation Classification System proposed for use in California is designed to simplify interdisciplinary communication about vegetation. The system structure is an aggregative plant community hierarchy at four levels of precision--the Association, Series, Subformation, and Formation. A flexible Phase category links specific resource management concerns to the system. The System is based on the concept of vegetation as an ecological component, and is neutral with respect to management function; design criteria stem from performance needs and principals of classification. The System is useful as a basic language and as an information framework for vegetation management activities.
