Aquatic Species

Early Detection and Rapid Response

Early detection is a comprehensive, integrated system of active or passive surveillance to find and verify the identity of new invasive species as early after entry as possible, when eradication and control are still feasible and less costly. It may be targeted at areas where introductions are likely, such as near pathways of introduction; or sensitive ecosystems where impacts are likely to be great or invasion is likely to be rapid. In Manitoba these speceis have been placed into two categories; Category 1 and Category 2

There are other aquatic plant species as well as fish and invertebrates listed that are not part of the EDRR list

Category 1 -Manitoba Wide Alert Weeds Priority Early Detection Invasive Plant Species Criteria for listing: - These invasive plants are not present in Manitoba, but maybe present in cultivation[1] but not yet known to have escaped, and/or - If listed as a Manitoba Noxious Weed, and/or - If on the List of Pests Regulated in Canada and - Capable of establishing in Manitoba based upon climate variables - A pathway of introduction exists - Easily identifiable with available resources Minimum Management Criteria (MMC): - Eradication is first option if detected and if feasible. - A lead agency should be identified and a management committee formed to develope an eradication strategy - An education and awareness program is required - Provincial ban on sale and trade. Species may be moved to next category if found in Manitoba [1] Cultivated as a garden plant, for ornamental horticulture, water ponds or gardens, for lawns; and is outside its natural range.
