🏆 Ecological Wonder — Pristine peatland ecosystem surrounding a 130-acre lake — one of the most important bogs in northern Maine
Salmon Brook Lake Bog is a pristine peatland ecosystem in Aroostook County — a vast bog surrounding a 130-acre lake. The bog is one of the most ecologically significant wetlands in northern Maine, supporting rare orchids, carnivorous sundew and pitcher plants, and boreal bird species at the southern edge of their range. Peatlands like this have been accumulating organic material for 10,000+ years since the last Ice Age, creating a living record of climate history preserved in the peat layers.

Frequently Asked Questions
Why are bogs ecologically important?
Bogs store enormous amounts of carbon in their peat — globally, peatlands contain twice as much carbon as all the world’s forests combined! They also preserve pollen records that scientists use to reconstruct thousands of years of climate history.
Why are bogs important for climate?
Peatlands cover only 3% of Earth’s surface but store twice as much carbon as all the world’s forests combined. Maine’s bogs have been accumulating carbon for 10,000+ years since the glaciers retreated. When peatlands are drained or burned, they release enormous amounts of CO2. Protecting peatlands is one of the most cost-effective climate strategies — simply leaving them alone keeps billions of tons of carbon locked underground.

Insider Tips
Peatland ecology: Salmon Brook Lake Bog is a classic Maine peatland — a wetland ecosystem dominated by sphagnum moss that accumulates as peat. Pro tip: Maine has more peatland than any other state in the lower 48 — these bogs store massive amounts of carbon. Carnivorous plants: Pitcher plants and sundews thrive in the nutrient-poor bog — capturing insects to supplement their diet.
Best Time to Visit
Summer: Carnivorous plants active. Fall: Bog turns brilliant red. Spring: Bog awakening. Winter: Frozen bog landscape.
Wildlife & Nature
Salmon Brook Lake Bog — a 3,400-acre peatland — one of the most significant bogs in Maine. The bog’s sphagnum mat, pitcher plants, cotton grass, and tamarack create an arctic-like landscape. Spruce grouse, palm warblers, and Lincoln’s sparrows breed here.
