CNPS placer county wikdflowers, and shrubs and trees books have been an invaluable resource. They are masterpieces and have helped plan our natives garden that will attract butterflies, bees, other beneficials and hummingbirds. CNPS's collaborative role in Calscape is monumental. Excellent organization for supporting habitat reatoration one home garden at a time. Great also for organic gardening. CNPS is simply the best!
California Native Plant Society is an exceptionally informative and supportive group, focused primarily on education and real outreach. They assist in everything from identifying plants on social media, to consulting with land use planners on best practices to maintain or restore native habitats. Their reach goes far beyond just plants, because when native plant habitats are preserved, whole areas and ecosystems are preserved. CNPS is non-judgmental and always mindful that they operate in the real world. They have become an excellent resource and community to thousands, and will continue to grow in importance as pressures increase on native ecosystems.
I have been a member of CNPS for many years. They have inspired me to make over my garden with native plants. CNPS provides any and all the information I could possibly need, first hand or through links to relevant partners. Books, maps, seminars, lectures, regular meetings, dedicated nurseries are all available to members and often to the community at large. Annual native garden tours are a wealth of information not only for help in choosing appropriate plants but also for ideas for infrastructure utilizing solar, eco-irrigation/graywater, insect and fauna habitat etc. One has immediate contact and conversation with local experts in these fields.
Their educational outreach in the realm of local political, community and land-use concerns is most comprehensive and effective.
