COSEWIC assessment and status report on the American water-willow Justicia americana in Canada.: CW69-14/809-2021E-PDF

"This aquatic wildflower of lake and river shorelines occurs at 13 sites in southern Ontario and southwestern Quebec. Although still locally numerous, its numbers have declined significantly in the past 10 years, driven by large losses from the Rivière des Mille Îles in Quebec. Declines are mostly attributable to unnaturally severe or prolonged water level fluctuations caused by water level management and climate change. Invasive species such as European Reed and Blue Cattail are likely to contribute to future population declines"--Reason for designation, page iii.
