Six species are now listed as Canadian Species at Risk. The Sydenham River historically supported the richest fieshwater mussel fauna of any river in Canada. Earlier surveys suggested that the community was in decline and many species were extirpated. We surveyed 17 sites on the river in 1997-1999 using a more intensive sampling efiiort than previous researchers, and found the fauna to be essentially intact; i.e., 30 of 34 native species were found alive"--Management Perspective, p. i. |
