The diversity of mammals at Second Marsh is relatively high for an urban wetland. However, increased urbanization has impacted habitat corridors and connections to the wetland for many species.

Second Marsh, the McLaughlin Bay Wildlife Reserve and Darlington Provincial Park ensure that the eastern movement corridor persists and continues to link the wetland to other natural areas. Do not be surprised to encounter White-tailed Deer or Coyotes when strolling down one of the paths that meander through the area.

The official list of Ontario mammals as determined by the Ontario Ministry of Natural Resources (OMNR, Oct. 1997) stands at 87 species. Of these, only 32 species have been documented in the vicinity of Second Marsh and McLaughlin Bay.
