The California Native Plant Society Rare Plant Program and Inventory.
Plants are rare for a number of reasons, both natural and anthropogenic. Over 2,000 rare and uncommon plant taxa are documented and tracked in the sixth edition of the California Native Plant Society's Inventory of Rare and Endangered Plants of California. Over 350 taxa were added to the sixth edition, of which a disproportionately large number occur on the fringes of the state. Nine plant taxa previously thought extinct in California were rediscovered in the last eight years. Inclusion of rare plants in the Inventory is based on an evaluation of data derived from all available sources and follows a set of formal criteria. The data development and review process draws upon the expertise of over 400 professional botanists throughout the state and occurs in collaboration with the California Natural Diversity Database. Discussions are ongoing regarding future directions for the Inventory, including on-line data evaluation and dissemination, review of the California Native Plant Society's list system and inclusion of locally rare and significant taxa.
