Recovery Strategy for the Tiger Salamander (Ambystoma tigrinum) (Great Lakes Population) in Canada (Proposed)


4. Potential effects on other species

Another consideration, beyond the biological and technical feasibility of recovery, is that, as a top predator, recovery of the Eastern Tiger Salamander may have significant impacts on another species at risk -- the Endangered Small-mouthed Salamander (COSEWIC 2004). In Canada, the Small-mouthed Salamander is currently present, but restricted to Pelee Island. This much smaller salamander would be potential prey for the Eastern Tiger Salamander, were Pelee Island to be selected as a potential recovery site. Notwithstanding, these two species do co-exist on Kelleys Island, Ohio in western Lake Erie (F. R. Cook pers. comm. 2008).
