CNPS is proud to be a conservation organization grounded in science. For six decades, CNPS has led the study and understanding of California’s native plants. From field guidelines and vegetation reports to the foundational Rare Plant Inventory and ranking system, CNPS serves as a daily resource for government agency staff, academics, and students. Today, CNPS and its partners are expanding that knowledge base with exciting new projects in big data mapping, locally rare species, and citizen science. Please consider supporting our efforts today!
