Assabet River National Wildlife Refuge encompasses 3.5 square miles located within the towns of Hudson, Maynard, Stow and Sudbury, which is approximately 20 miles west of Boston. The refuge has a large wetland complex, several smaller wetlands and vernal pools, and large forested areas which are important feeding and breeding areas for migratory birds and other wildlife.
