Summary

In today's episode, host Emily Kwong leads us on a night hike in Patuxent River State Park in Maryland. Alongside a group of naturalists led by Serenella Linares, we'll meet a variety of species with unique survival quirks and wintertime adaptations. We'll search out lichen that change color under UV light and flip over a wet log to track a salamander keeping warm under wet leaves. Emily may even meet the bioluminescent mushrooms of her dreams. Plus, we talk about community events to get outside, such as the City Nature Challenge and Great American Campout.
