A Biodiversity Walk with Peter Alden
After leading an evening program at Fresh Pond, Peter Alden, well-known
naturalist, author and lecturer, autographed books for participants.
Peter took the group all of the way around the Pond, identifying species
of plants and animals as we walked. Beforehand he promised that we would
be able to identify at least 100 species: We listed 133.
