Recovery Strategy for the Dwarf Wedgemussel (proposed)

3. Critical Habitat

3.1 Identification of the Species’ Critical Habitat

Because the dwarf wedgemussel is extirpated in Canada and there is little information on historical ecology or habitat use, it is not possible to specifically identify critical habitat for the species. Important habitat for the species within the Petitcodiac would have been in flowing waters of high oxygen and low sediment, with areas of sand or fine gravel bottom.
