The Tobique Island Nature Preserve is within traditional Wolastoqiyik territory. The preserve was acquired in March 2019. The whole island is now under conservation, increasing the protected land in the upper Wolastoq (Saint John) River watershed.


The island consists of cobblestone and sand beach on the eastern, western and northern sides. The remainder of the island is dominated by black ash, with balsam poplar, cherry and aspen scattered throughout. The understory is dominated in the forested areas by ostrich fern.
