I have a high school student who needs to do an activity where he examines lichen on trees. We are in College Park, MD, near the Metro. Do you have any suggestions where he might find what he's looking for? Thanks!
You can find lichen on trees almost anywhere. Yards, parks. Older trees are more apt to have tree fungus, so go to an older neighborhood, park or area of the park with mature trees.
