As the days get cooler and frost is in the air, deciduous trees and shrubs put on an autumn show in all shades of red, yellow, orange, and purple. Join Emily Southgate and Loudoun Wildlife Conservancy for a walk in the woods to enjoy all the colors that Mother Nature provides this time of year. We’ll discuss various tree species and why trees change their color in the fall. Limit 20. Registration required: Sign Up Online.
