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!
Support Nature. Support SVT.
Everything in nature is interconnected—from the smallest insects to the towering trees—and SVT works tirelessly to protect this delicate web. By donating to SVT this Earth Day, you will make an impact not only on the health of our region but on the environmental health of the entire planet.
