Learn about the cues plants and animals use to shift from winter slumber to spring exuberance. Using observations collected from the Arboretum, learn the biology of seasonal change, current ideas about its evolutionary advantages and how you can contribute valuable data for the National Phenology Network, a group that brings together citizen scientists and non-profits to monitor the impacts of climate change on plants and animals in the U.S.

Class instructor Phyllis Baudoin Griffard is an award winning biology educator who has taught tailored courses for elementary teachers to pre-medical students. Participants who complete the class will receive an Arboretum Certificate of Achievement in Science and Nature. Teachers receive two hours of SBEC credit and Master Naturalists receive two hours of advanced training for taking the class.
