Critical Habitat Orders

Critical Habitat of the Lake Chubsucker (Erimyzon sucetta) Order

The long-term recovery goal (greater than 20 years) set out in the Recovery Strategy for the Lake Chubsucker (Erimyzon sucetta) in Canada is to maintain current populations of the Lake Chubsucker and to restore viable populations to formerly occupied wetland habitats. Efforts to achieve this recovery goal are ongoing and involve a number of recovery objectives outlined in the Recovery Strategy for the Lake Chubsucker (Erimyzon sucetta) in Canada. Threats to this species include siltation, increased turbidity, nutrient loading, and loss of its preferred wetland habitat (clear, still, well-vegetated waters) through habitat alteration, channelization, wetland drainage, pollution, changes to rates of flow, and possibly exotic species and climate change. In Southwestern Ontario, the leading causes of habitat loss for this species appear to be the draining of wetlands, as well as siltation and nutrient loading due to agricultural practices. Protection of critical habitat is an important component aimed at ensuring the recovery of the Lake Chubsucker, particularly given its extremely limited distribution in Canada.
