Canadian environmental sustainability indicators : invasive alien species in Canada. : En4-144/65-2024E-PDF

"Plants, animals and microorganisms that have moved beyond their native range to a non-native ecosystem are known as alien species. When the introduction and spread of alien species threaten the new environment, economy or society (including human health), they are considered invasive. Invasive alien species can cause environmental and economic damage to our waterways, food supply and natural resources. For the purposes of this indicator, species are considered "established" when a reproducing population exists in Canada and eradication efforts have been abandoned. They are also considered "regulated" only if regulatory measures are federal in scope. This indicator reports the number of federally regulated invasive alien species that have become established in Canada since 2012"--Page 4.
