NA Phenology Campaign

North America Phenology Campaign

Congratulations to the students that participated in the Spring Phenology Campaign!

In the video below (<1 min) hear from scientists why it is important to study phenology. 


Fall Dates: September - December      Spring Dates: February - June

The North America Phenology Campaign is focused on monitoring and reporting plant phenology data to help validate the timing of the plant growing season. In this campaign, students will observe and report plant green-down and green-up, have opportunities to meet scientists, and collaborate with other students.

Register at any time for the Fall Phenology Campaign through the link below!

What to Expect

  • Webinars for learners and educators
  • Resources that support the content
  • Information about phenology-related opportunities
  • Collaboration opportunities
  • Certificates and badges for active schools/organizations

Wildlife Biologist Ready to Answer Phenology Questions

What questions do your students have about phenology? Dr. Dave Steinberg is a wildlife biologist at the University of New Hampshire. His research focuses on the changes in the timing of amphibian reproduction and green-up in trees in a warming climate. Dave is ready to answer your questions! Learn more on the Phenology Campaign Webinars page.
