What do we do?

Chapters -- The CNPS program is wide-ranging and offers something for everyone interested in plants. Chapters conduct regular field trips to see interesting plants and plant communities, and invite speakers to share their knowledge at monthly meetings. In addition, many chapters conduct annual native plant sales and wildflower shows.

Education, Conservation and Legislation -- CNPS conducts a variety of educational programs and conservation efforts all focused on long-term protection and preservation of the native flora in its natural habitat. Our activities include preparing local plant lists, supporting establishment of protected reserves for native plants, monitoring and reducing the spread of invasive non-native species, and providing expert testimony on plant issues. By observing a consistent policy of objectivity and cooperation, CNPS botanists have earned an outstanding reputation among government agencies and other conservation groups.

Plant Science -- CNPS has been a recognized leader in the monitoring and protection of endangered plants for almost 50 years. The CNPS Rare Plant Program maintains an objective, scientific inventory of endangered and rare plants of California. This information is summarized in the CNPS Inventory of Rare and Endangered Vascular Plants of California. The Plant Communities Program has prepared and standardized an updated classification of California's plant communities, resulting in A Manual of California Vegetation.

Publications -- CNPS produces several publications: Fremontia, a journal with articles on all aspects of native plants; The CNPS Bulletin, a statewide report of activities and schedules; chapter newsletters; and a series of wildflower posters. CNPS also publishes a number of books such as floras of local areas and advertises these through its book catalog and in our web-based bookstore.
