This nature preserve is 75.4 hectares (186.3 acres), protecting about 2 km of shoreline along the St. Croix River and across the river from the Moosehorn National Wildlife Preserve on the U.S. border. This floodplain habitat provides home for many rare plant species.


The Beausoleil Nature Preserve is within traditional Peskotomuhkati territory and was acquired from Pat Beausoleil in 2019 for permanent protection.



The habitats found on the Beausoleil Nature Preserve provide ideal conditions for many rare and uncommon species. For some of these species such as Sweet Wood Reed Grass (Cinna arundinacea), lowland yellow loosestrife (Lysimachia hybrida), Nannyberry (Viburnum lentago) and Northern Arrow-wood (Viburnum dentatum), this is the only location they can be found in abundance, making this preserve along the St. Croix River very unique.
