The USA-NPN National Phenology Database can serve as the long-term archive for phenology data collected by members of partnering organizations. Several current USA-NPN partners, including the Arbor Day Foundation, Monarch Watch, and HoneyBeeNet, are housing phenology records in the National Phenology Database.

Use of Nature's Notebook standards are encouraged; data collected following these standards can be viewed using USA-NPN visualization tools. Data collected not following Nature's Notebook standards can also be archived in the National Phenology Database but will not be accessible through USA-NPN visualization tools.
