The USA-NPN—a network of scientists, resource managers, educators, and volunteer observers supported by a National Coordinating Office—serves science and society by collecting, organizing and distributing phenological data and information to stakeholders to aid decision-making and adaptation to variable climates and changing environments.
We are happy to give you information about:
- What is phenology, and why should I care about it?
- How do we know when spring is arriving, and how is the timing of spring changing?
- How does the USA-NPN predict the activity of plant and animal species of interest?
- How can people get involved in Nature's Notebook?
Have another question? Just ask!
Professional and citizen scientists alike are invited to participate in Nature's Notebook, the USA-NPN's national phenology program in which participants record long-term observations of plant and animal life stages. This program is the primary way that phenology data are added to the National Phenology Database.
Our Status of Spring maps provide insight into when early season plants begin to leaf out and bloom across the country. The maps show when spring leaf out and bloom arrived, and how this year compares to a long-term average.
Our Pheno Forecasts provide notifications for when pest and invasive species are estimated to reach life cycle stages when management actions are most effective.
The USA-NPN logo may be used in print and on the web by USA-NPN partners and by the media. The logo may be resized as needed, provided it is scaled proportionately, and the words “National Phenology Network” are legible.
The Nature's Notebook logo may be used in print and on the web by USA-NPN partners and by the media. The logo may be resized as needed, provided it is scaled proportionately, and the words “A project of the USA-NPN” are legible. In text, Nature's Notebook should be italicized.
- USA-NPN (not NPN alone) is the abbreviation.
- “Taking the Pulse of Our Planet” (not ‘the Planet’) is our tag line.
- Phenology is the study of the timing of seasonal plant and animal life cycle events, including the flowering of plants, ripening of fruit, the emergence of insects, and migration of birds.
- The host institution of the USA-NPN is the School of Natural Resources and the Environment, College of Agriculture and Life Sciences at the University of Arizona (snre.arizona.edu). Several institutions and agencies are responsible for the funding of the USA-NPN – ask our media contacts whom to credit for a particular effort.

We recognize hundreds of USA-NPN Partners. Anyone who participates in Nature’s Notebook or collaborates with NCO staff to advance the science of phenology or to inform decisions is part of the USA-NPN.
Our sponsors are listed at the bottom of the USA-NPN homepage.
