Wildlife
We used a program called NEWILD
(New England Wildlife) to figure out
which species we might encounter.
We plugged in data about the forest
habitat of each site, and the program
came out with a list of species that would
reside in that area.
This gives us a list of species that people
can look for and are likely to see at each
site.

Thrush, Least Flycatcher

Cardinal, Woodland Vole
