The mixed pine/deciduous has been there since 1937

The white pine and young deciduous/shrub were cleared land

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.

Site B: White Breasted Nuthatch, Wood Thrush, Least Flycatcher

Site C: Downy Woodpecker, Northern Cardinal, Woodland Vole

Site D: Eastern Garter Snake, Ruffed Grouse, White Footed Mouse
