  • Mission:
  • The mission of the California Native Plant Society (CNPS) is to conserve California native plants and their natural habitats, and increase understanding, appreciation, and horticultural use of native plants.

  • Overview:
  • The California Native Plant Society is a statewide nonprofit organization that advances the understanding, appreciation, and protection of California‚Äôs native plants and habitats, through scientific activities, education, horticulture, and conservation. CNPS was founded in 1965 by grassroots activists who recognized the need for a plant conservation advocacy organization in California. For 50 years, CNPS volunteers and staff have worked alongside scientists, government officials, and regional planners to protect habitats and species and to advocate for well-informed environmental practices, regulations, and policies. CNPS maintains the online Inventory of Rare and Endangered Plants (Inventory) and published A Manual of California Vegetation (MCV), the standard vegetation reference relied upon by state and federal agencies. CNPS is also a grassroots organization, with nearly 10,000 members in 34 chapters in California and Baja that promote our mission at the local level.

  • History:
  • CNPS was founded in 1965 by Bay Area grassroots activists who came together to save a botanic garden of California native plants. Recognizing the need for a statewide plant conservation advocacy organization in California, CNPS was founded as a result of their success. In the 50 years since, CNPS has grown to 10,000 passionate members and volunteers located in 34 regional chapters throughout California and NW Baja California, and has become the preeminent environmental organization advocating for the conservation and appreciation of native plants and their habitats in California. Some of our recent successes include the five year old citizen science initiative, "Rare Plant Treasure Hunt" (RPTH), directly impacting conservation in California by updating 2,500+ occurrences of rare and endangered species - one third of which were new to science; as a member of the Desert Renewable Energy Conservation Plan (DRECP) Stakeholder Committee, CNPS increased the number of vulnerable species and habitats to be conserved within the 5.5 million acres of Mojave Desert slated for development; CNPS passed AR173 in the California state legislature establishing California Native Plant Week, and was instrumental in including language in a 2012 state forestry tax bill requiring annual ecological performance reports on California's forests; and developed a free children's curriculum which aligns with State of California science and language education standards to teach children a love of the outdoors.
