Phenology at the Ney Nature Center

Are you observant? If you are, you might be interested in helping us out with our phenological calendar. Phe-nol-o-gy is the study of changes in plants and animals as they respond to weather, climate, and the seasons. Each spring we anxiously await the first returning robin in the hope of warmer weather. That is a phenological event. It happens every year but the return date depends a lot on the weather. Migration and flowering are two more examples of phenological events. You can make observations at the Ney Nature Center and share them with us using Facebook and iNaturalist. Below is a monthly list of phonological events to look for but all observations are a part of phenology, so don’t limit what you are reporting to what is on the list!

We will be using this page to create species lists for the Ney Nature Center! Check back as we build the lists and observations!
