newly established invasive alien species in Canada.
“The Newly Established Invasive Alien Species in Canada indicator is part of the Canadian Environmental Sustainability Indicators (CESI) program, which provides data and information to track Canada's performance on key environmental sustainability issues. The main indicator is the number of invasive alien species found to be newly established in Canada, reported by year of establishment and regulatory status. This provides a preliminary indication of the potential harmful consequences of new arrivals. Species are deemed to be established when they are successfully reproducing in Canada and any eradication efforts have been abandoned. Should a new invasive alien species be found to have established, its federal regulatory status (whether that species was regulated or unregulated, as well as whether the pathway of invasion was regulated, unregulated, or unknown) will be reported. It should be noted that some pathways cannot be controlled, particularly if species arrive as a function of natural spread. The proportion of regulated species that have not established in Canada is a partial measure of regulatory success. For the purposes of this indicator, species are considered regulated only if regulatory measures are national in scope"--p. 6.
