Response Statements

Response Statement - Colicroot

This perennial herb is restricted to remnant, disturbance-dependent prairie habitats in southwestern Ontario. It continues to decline in the face of multiple threats, including habitat modification, invasive species, and browsing by deer. Prairie habitat, for example, naturally transitions to less suitable habitat types in the absence of periodic disturbance (e.g., fire), and its quality and extent are also vulnerable to ongoing urban and industrial development. Recent construction of a new transportation corridor caused the removal of more than 50% of all mature plants in the Canadian population and loss of habitat. Although plants have been transplanted from the transportation corridor to nearby restoration sites, it is too early to know whether these relocated subpopulations will be self-sustaining so they cannot yet be considered to contribute to the population.
