The March equinox is the perfect time to think about spring unfolding. Phenology – noting the periodic occurrences in the natural world – is both art and science, practiced for millennia across cultures and regions. Learn about different approaches and maybe find your own. Instructor: Kathy Miner, Arboretum naturalist. Indoor class. Fee: $20. Register by March 18 @ https://arboretum.wisc.edu/classes/phenology-keeping-track-of-nature-2025/ . Meet at the Visitor Center.
