Phenology, as defined by Freshwater, "is the science of tracking biological & physical events of nature in relationship to weather & climate"

to submit your data

Make every Friday a Phenology Friday
and submit YOUR Observations!

Jeffers is teaming up with teachers and students across Minnesota to collect and share phenological data they are observing in their schoolyards, neighborhoods, and communities

Observations could include:
  • lists of sightings such as bird migrations, signs of animals & animal tracks, flowering of plants, leaf emergence in the spring & color change in the fall, freeze-over & ice-out dates of local lakes & ponds, etc
  • sensory observations: feels like, sounds like, smells like, looks like
  • poems inspired by observations
  • pictures
  • more!

Submit your observations and read the data submitted from the previous week by
teachers & students from across the state

We encourage YOU to become a community of observers!
