If you would like to share an historical or contemporary phenology dataset, you can add it to our legacy dataset registry. The registry maintains a list of datasets, permissions for sharing them, and information on how to access them. These datasets are searchable by taxonomic group, phenophase, format, and other relevant identifiers. This module allows valuable historical datasets that may otherwise be lost to be archived and made available for researchers and decision-makers to access. The USA-NPN plans to develop the capacity to host phenological datasets collected according to a variety of methods in the future.

If you have phenological datasets you would like to register, please visit the USA-NPN legacy data registry.
