The Island Group has 22 indigenous vascular plant species and 21 alien plant species. There are three seal species on the Island Group - Southern elephant seal, Antarctic fur seal, and sub-Antarctic fur seal. There are no indigenous land mammals on the islands.

It is not known whether Prince Edward Island has any perennial watercourses due to the infrequent visits to the island.
