SVT is responsible for the protection and care of diverse conservation lands that include wetlands, sensitive habitats, trails and other open spaces including major sanctuaries. Many of these properties have trail maps, which can be found below. Click on the property name for more information and directions to parking.
The Land Protection and Stewardship staff are always on the look out for new properties under threat of development or help in maintaining our current responsibilities. If you would like to get more information about assisting this team, please visit our Volunteer page or call us at 978-443-5588.
A fun way to encourage children and other reluctant hikers to visit the outdoors is Letterboxing. SVT encourages you to search for them on an SVT property near you!

Although small itself, the Elliott Concord River Preserve directly abuts over 900 acres of the Great Meadows National Wildlife Refuge, which in turn is contiguous with another 760 acres of additional protected open space, mostly to the north. To the south, only a small, undeveloped inholding separates this 1,600+ acre complex from another 200 acres of National Wildlife Refuge (the Concord Impoundments), which in turn connects across the river to other protected open space in Concord and back into Carlisle, including historic Estabrook Woods.
Striking features catch your eye as you explore this conservation area. North Brook rattles and gurgles, slipping under a flat slab of rock and widening into a quiet pool on its way through the property and eventually to the Assabet River.
