Big Wood Trail is in the Indian Point Blagden Preserve, most of which is in a forest. This forest is populated by tall red spruce, white cedar, and balsam fir, yellow and white birch, red oak, and red maple, which are locally common. The trees are mostly mature; some of them were cut down years ago but are growing back. Hikers here have the opportunity to see white-tailed deer, porcupines, snowshoe hares, ruby-crowned kinglets or osprey, about 12 species of warblers, and 6 members of the woodpecker family, including black-backed and pileated woodpeckers.
