Application of the Residence Concept to the Anticosti Aster (Symphyotrichum anticostense) in Canada

Does the concept of residence under SARA apply to this species? No

Detailed Rationale:

(1) Does the ecology of the species include the use of a dwelling place--which is a specific location (or locations) or discrete spatial area that contains features similar to a den or nest, or performs functions similar to a den or nest?
No - the specific location occupied by an individual Anticosti Aster plant is plainly a part of the general habitat of the species; there is no inherent feature of this area similar to a den or nest.

(2) Are these locations occupied or habitually occupied during all or part of the species’ life cycle? NA

(3) Are these locations essential to the successful performance of a specific, crucial function of the species’ life-cycle? NA

Summary of Rationale:

Individual Anticosti Aster plants do not appear to use a dwelling place similar to a nest or den, and therefore do not qualify for having a residence. Therefore, there is no additional legal protection for the species over and above the protection already afforded the individual and its critical habitat.
