Invasive alien species in Canada – Known Newly Established Invasive Alien Species in Canada
The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Invasive alien species in Canada main indicator is the number of invasive alien species found to be newly established in Canada, reported by year and regulatory status. This provides a preliminary indication of the potential harmful consequences of new arrivals. A secondary indicator, the proportion of regulated species that have not established in Canada, is reported as a partial measure of regulatory success. Regulation of potentially invasive species is intended to prevent their introduction and establishment in Canada. Species are added to the list of regulated species based on an analysis of risk. Both indicators report on species establishment since January 2012. With the implementation of the Federal Sustainable Development Strategy 2010–2013, this type of information began to be collected consistently across multiple programs, allowing information to be combined for the first time into a single indicator despite the varying approaches used to control different groups of invasive alien species. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for data sources and details on how those data were collected and how the indicator was calculated.
