NSERC Canadian aquatic invasive species Research Network II (CAISN II)

Introduction and spread of invasive non-indigenous species (NIS) is recognized as one of the greatest threats to global biodiversity. Invasive NIS also cause up to $1.4 trillion annually in global damage and control costs. In Canada, the Great Lakes have sustained invasions by at least 185 NIS, while a further 112 and 76 NIS have established on the east and west coasts, respectively. We are uncertain how many NIS exist in Arctic ports because surveys have never been completed. The Canadian government has been ramping up its capabilities on NIS in response to three critical reports by the Auditor General, however a number of critical gaps remain. The NSERC Network on Aquatic Invasive Species (NAIS) will address these gaps by conducting a coordinated set of comprehensive studies directed at four research themes pertaining to aquatic NIS: i) early detection strategies; ii) rapid response strategies; iii) AIS as part of multiple stressors affecting aquatic ecosystems; and iv) reducing uncertainty in prediction and management. Our projects will be conducted in aquatic ecosystems across Canada, including the Gulf of Saint Lawrence and Strait of Georgia, St. Lawrence, St. Clair and Red Rivers, Laurentian Great Lakes, mountain lakes in Alberta, and ports across the Canadian Arctic. Projects will be conducted in conjunction with partners from the shipping industry, from federal and provincial governments, and NGO partners. NAIS will provide, for the first time, a comprehensive profile of aquatic NIS established in waters spanning the entire country, and develop tools that can be used for early detection of and rapid response to invaders. We also will assist managers with critical decision making regarding if, when and where mitigation measures should be implemented to eradicate, control, or stop spread of aquatic AIS. The network will prepare Canada for commercial shipping through Arctic waters in conjunction with climate warming. NAIS will train a large group of young Canadians to provide future leadership such that the number of new NIS that establish in Canada is reduced. NAIS also will contribute to policy and educational reforms in Canada based upon review and analysis of on-going programs here and in countries world-wide.
