Costs and Threats of Invasive Species to Alberta's Natural Resources by A. S. McClay,Alberta. Alberta Sustainable Resource Development Pdf
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.
