Critical Habitat Orders

Critical Habitat of the Spring Cisco (Coregonus sp.) Order

The recovery goal, as set out in the Recovery Strategy, is to improve the status of the Spring Cisco and increase the species’ abundance. Efforts to meet the population and distribution objectives are ongoing and supported by the measures described in the Recovery Strategy. Current threats to the Spring Cisco, as identified in the Recovery Strategy, include new residential areas (principal and secondary residences) that have gradually been built along the banks of Lac des Écorces. The water quality, and therefore the quality of the Spring Cisco’s habitat, has deteriorated. Additionally, many fish species have been introduced to the lake to encourage recreational fishing. The recent colonization of the lake by the Rainbow Smelt (Osmerus mordax), noted in 1999, seems to have become the main threat to the Spring Cisco’s recovery, since the Rainbow Smelt is a predator and competes with ciscos.
