The Emily Winthrop Miles Wildlife Sanctuary manage 1,500 acres of habitat amidst 5,000 acres of protected open space. In addition to forest land, Miles features two miles of the Carse Brook Wetlands that supports a wide variety of flora and fauna, some on the endangered species list.  Though none of the buildings are currently open to the public, the sanctuary itself is open for visitation and the trail around Miles Pond boasts some of the best wildlife viewing in the region.

The Emily Winthrop Miles Wildlife Sanctuary is the training and research part of Audubon Sharon's operation. With a small residential facility, Miles is able to house interns and scientists who use the Sanctuary for field work and environmental study.
