USA National Phenology Network

What We Do

The USA National Phenology Network (USA-NPN) monitors the influence of climate on the phenology of plants, animals, and landscapes. We do this by encouraging people to observe phenological events like leaf out, flowering, migrations, and egg laying, and by providing a place for people to enter, store, and share their observations. We also work with researchers to develop tools and techniques to use these observations to support a wide range of decisions made routinely by citizens, managers, scientists and others, including decisions related to allergies, wildfires, water, and conservation. See our vision and mission statement for more information.

Who We Are

The USA-NPN is comprised of many partners including federal, state and local agencies, universities, colleges and schools, non-governmental organizations, citizen volunteers, and many others. Our participants range from individual observers making observations in their backyards to professional scientists monitoring long-term plots. Our network is described in further detail on the Network Structure page. We invite you to join us.

How We're Organized

The efforts of the USA-NPN are organized and directed by the staff at the USA-NPN National Coordinating Office at the University of Arizona, with support from the US Geological Survey, the National Science Foundation, and many other funding agencies, organizations, and partners. The USA-NPN is governed by an executive committee consisting of a 12-member Board of Directors, the NCO Executive Director, and Assistant Director, as specified in our Constitution. Several Working Groups have also been established within the USA-NPN to address specific issues within the field of phenology. Details on the development of the USA-NPN can be found on the History page.
