California Phenology Project

The California Phenology Project (CPP) was launched in 2010 as a 3-year pilot project funded by the National Park Service Climate Change Response Program to develop and to test protocols and to create tools and infrastructure to support long-term phenological monitoring and public education in California. A primary focus of the effort has been to recruit and engage California residents and visitors in the collection and interpretation of phenological data.  After more than five years of phenological monitoring, the CPP is still growing strong. Participants have recorded -- and uploaded into the USA National Phenology Network's user-friendly interface, Nature's Notebook -- almost 1,300,000 phenological observations of the phenological status of wild plant species in California.

The CPP initially focused on monitoring woody plant species in seven pilot parks, encompassing desert, coastal and mountain biomes, and building upon existing monitoring protocols and programs of project collaborators.  With the help of many partners, volunteers, and docents who attended CPP-led training workshops, phenological monitoring is now being conducted in California in over a dozen regional and state parks, botanical gardens, private reserves, and University of California Natural Reserves, where ~30 native plant species are now being monitored.

Project collaborators include the National Park Service (NPS), the University of California, Santa Barbara (UCSB), and  the National Coordinating Office of the USA National Phenology Network (USA-NPN)
