COSEWIC assessment and status report on the lakeside daisy Tetraneuris herbacea in Canada. : CW69-14/296-2021E-PDF
"This perennial herb occurs only in the Great Lakes region where it is restricted to rare alvar and lakeshore calcareous bedrock habitats. Ninety-five percent of the world population is in Canada. This species may be very abundant where it occurs, and a few large subpopulations on western Manitoulin Island buffer the level of risk to the rest of the population. Ongoing threats include fire suppression, trampling by pedestrians, off-road vehicle use, building and road construction, quarrying, logging in adjacent forests, and invasion by exotic species. The change in status since the last assessment is the result of increased search effort and a change in interpretation of severe fragmentation"--Reason for designation, page iii.
