Proceedings of the Regional Peer Review of the Recovery Potential Assessment – River Darter, Percina shumardi, Great Lakes-Upper St. Lawrence Populations (Designatable Unit 3); January 31, 2019
Chairperson: David Andrews
Editor: Jofina Victor
Summary
A regional science peer-review meeting was held on January 31, 2019 in Burlington, Ontario. The purpose of the meeting was to assess the recovery potential of the Great Lakes-Upper St. Lawrence populations (Designatable Unit [DU] 3) of River Darter (Percina shumardi), to provide advice that may be used for the listing decision, development of a recovery strategy and action plan, and to support decision making with regards to the issuance of permits and agreements. Participants included DFO Science, Species and Risk, Policy, and Fisheries Protection programs, Ontario Ministry of Natural Resources and Forestry (OMNRF), and regional Conservation Authorities.
The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) designated River Darter in DU 3 as Endangered in 2016. This species has a very restricted distribution, occurs at few locations, and is exposed to a number of threats including shoreline hardening, exotic species, dredging, and nutrients and effluents from urban waste, spills, and agriculture.
This proceedings report summarizes the relevant discussions from the meeting and presents recommended revisions to be made to the associated research documents. The Proceedings, Science Advisory Report, and Research Documents resulting from this science advisory meeting are published on the DFO Canadian Science Advisory Secretariat (CSAS) website.
