Rare Animals

There are no documented occurrences of rare animals within this Ecoreserve. For more information on rare animals in Maine, visit the Maine Department of Inland Fisheries and Wildlife.


Located in eastern Aroostook County, the Salmon Brook Lake reserve captures many ecological features characteristic of Maine's northeastern limestone belt, including circumneutral fens, northern white cedar swamps, and numerous rare plants. While only 363 reserve acres are upland, 610 acres were classified as regulated, suggesting that much of the forested wetlands support merchantable timber. Saturated soils cause slow growing conditions, however, and a six inch tree was aged to be over 200 years old. There is little information on harvesting history within the reserve.

An ATV trail traverses the west side of the Reserve, and a recently constructed trail at the southwest perimeter provides access for small boats.
