The human and resource support of our native plant community is larger than many realize. Here we list links to useful and favorite resources beyond CNPS. 


For Species Identification and Distribution Information...


A repository for information on California wild plants from diverse sources, including public agencies, academic institurions, private organizations, and individuals. A great resource for identifying what grows where.
