Nature and Ecology is the “real thing” at Highland Green. As part of the initial development of the community, a third of Highland Green’s vast 635 acre campus was preserved for permanent conservation through the Brunswick Topsham Land Trust. The 230 acre Cathance River Nature Preserve abuts the beautiful Cathance River and has five miles of maintained trails. The 30 acre Heath Sanctuary at the very center of Highland Green is a prime bird-watching area. The Cathance River Education Alliance (CREA) is a not-for-profit organization that maintains the Cathance River Ecology Center, provides nature education and fosters wise use of the Preserve.

Highland Green won a prestigious 50+ Housing Council Award for Best Integration of Nature and Landscaping at the 2014 International Builders’ Show in Las Vegas. The unprecedented incorporation of conservation at Highland Green gives its residents the chance to embrace Maine nature within the security of the community and for unique volunteer opportunities with trail maintenance, nature-based education, and more.
