Protecting natural areas and farmland around
the Sudbury, Assabet, and Concord Rivers
Join an SVT BioBlitz!
This spring, SVT is planning a BioBlitz at Smith Conservation Land. We're recruiting dozens of volunteers to walk the land to photograph and catalog the wildlife that live there. Please help out!
SVT Big Sit
On June 1, SVT, the Boston Birding Festival, and Boxborough Birders invite you to a "Big Sit" Birding Event at Wolbach Farm. While relaxing in this beautiful setting, we'll enjoy watching the birds that forage, display, and nest in the fields. Everyone is welcome!
Weed Warrior "Drop In" Days
In May and June, SVT is leading Weed Warrior "Drop In" Days at our Smith Conservation Land and Wolbach Farm properties. Everyone is invited to drop in at anytime during these events to help out for as long as you can. No experience necessary!
Help Expand Ashland's Town Forest
SVT supported the Town of Ashland in its acquisition of 53 acres that abut the Town Forest/Cowassock Woods Conservation Area, and we will soon hold a conservation restriction on the land. Please help us raise funds to protect this important habitat.
Get Outside with SVT
