National Park Service
Since 1916, the National Park Service has been caring for our national parks,
preserving and protecting America's special places. The NPS also provides technical, planning and limited financial assistance to National Heritage Areas, including the Freedom's Way Heritage Area. The NPS is a partner and advisor, with decision-making authority remaining in the hands of local people and organizations.

U.S. Fish and Wildlife Service
Part of the U.S. Department of the Interior, the Service conserves, protects, and enhances fish and wildlife and their habitats for the benefit of present and future generations. Service biologists contribute to the health of our environment — and consequently our quality of life — by protecting and restoring important habitat, safeguarding endangered species, minimizing environmental contamination, and restoring fish populations. In addition, the Service provides funds to support state fish and wildlife programs and enforces federal laws protecting wildlife.

Beaver Brook Association
Beaver Brook Association is an educational non-profit founded by Hollis P. Nichols and Jeffrey P. Smith of Hollis, NH, to foster land stewardship awareness and encourage a sense of appreciation for the natural world. Begun with just 18 acres of land in 1964, Beaver Brook has blossomed into over 2,000 acres located in Hollis, Brookline, and Milford. Hiking, biking, horseback riding, bird watching, and many other activities are enjoyed daily on the nearly 35 miles of trails.
