Have you seen the luminous, lovely lichens lurking on most outdoor surfaces? It's time to quit overlooking them and start going over to look at these ubiquitous, stunning critters covering trees, rocks, and buildings.

Co-hosts Charlie Mitchell (phenology coordinator, lichen looker) and Heidi Holtan (Director of Public Affairs, cautious cross country skier) delight in an insightful interview with Chad Kaddatz, our partnering phenology teacher from Little Falls Middle School.

In addition, we hear from John Latimer on the surprising winter adaptations of chickadees.
