Description:
Pembina Trail Preserve lies on a prominent beach ridge at the eastern edge
of Glacial Lake Agassiz. The site is associated with the Pembina trail, a major
ox-cart route that traders used to haul furs and supplies between Winnipeg and
St. Paul. The Pembina Trail Preserve is one of the most spectacular prairies in
northwestern Minnesota. It displays the forb and grass species typical of mesic
tallgrass prairie, with large areas of meadow, marsh, and shrub swamp, as well.
Patches of aspen, spring-fed wetlands and a small calcareous fen lie at the base of the low, sandy
ridges. Rare plant and animal species include hair-like beak rush, marsh arrow-grass, sticky false
asphodel, upland sandpiper, yellow rail, marbled godwit, greater prairie chicken, Wilson's
phalarope, and Dakota skipper. Sandhill cranes gather here by the thousands during spring and fall
migration. Moose are commonly seen. Visit in spring to observe its animal diversity, or in late
summer to view asters, sunflowers, blazing stars, and goldenrods in bloom.
