Invasive Species Council of Manitoba

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
