Recovery strategy for the western silvery aster (Symphyotrichum sericeum) in Canada . : En3-4/276-2017E-PDF
"The Western Silvery Aster (Symphyotrichum sericeum) is a perennial wildflower, producing 30-70 cm tall sparsely branched upright stems from a corm-like rootstock, with purplish aster flowers, and silky-hairy leaves. Recovery is considered feasible for this species. The population and distribution objectives are to maintain the population size and distribution, within the natural range of variation, at all extant populations as well as any newly discovered or reconfirmed populations to ensure the long-term persistence, and where feasible, the natural expansion of Western Silvery Aster in Canada. Broad strategies to be taken to address the threats to the survival and recovery of Western Silvery Aster are presented. Critical habitat for Western Silvery Aster is fully identified in this recovery strategy for all extant populations in Canada”--Executive summary, p. iv.
