This review focusses on invasive species affecting forestry, provincial grazing land, aquatic & wetland environments, and natural ecosystems in Alberta. Based largely on examination of the literature, major invasive species are listed under the following categories: terrestrial plants; terrestrial vertebrates; terrestrial invertebrates; aquatic organisms, including fish, plants, insects, mollusks, & protozoan parasites of fish; and plant & wildlife diseases. For each species, information is included on its status, geographic distribution, habitat, and economic & ecological impact. The review also discusses pathways & sources of new introductions and potential threats of new introductions in each species category. The final chapter presents an overall evaluation of invasive species & their impacts, pathways, and future risks. It also notes knowledge gaps.
