Listening to Nature with Bioindicators
January 24, 2026 @ 2:00 pm - 3:30 pm
Nature is always speaking to us! Join Abby at the Boyden Wildlife Refuge to discover how we can learn about the health of our ecosystems by studying something called a bioindicator: a species that signals whether environmental conditions are thriving or under stress. After discussing and exploring biofacts from several Massachusetts bioindicator species, we’ll conduct an air‑quality experiment and search for a very special bioindicator found almost everywhere in our watershed… lichen!
**Update: Main portion of the program will be held inside building at Boyden Wildlife Refuge. A shortened walk will follow due to the forecasted frigid temperatures.**
Registration required. FREE for everyone!
