The following photo guides are supplementary materials available to assist with the identification of Nature's Notebook phenophases in individual species. Many of these guides have been developed for specific regional or local efforts, such as a USA-NPN Campagin , but all have been vetted by the staff of the USA-NPN National Coordinating Office. If you would like to view the full list of species profile pages created by the USA-NPN please return to the Species Search page. Two of our partners have made a series of phenophase photo guides not shown here. Check out the New York Phenology Project (NYPP) phenophase photo guides and the California Phenology Project (CPP) ones. If you'd like to create phenophase photo guides for your own project, please visit this webpage for guidelines and templates.
