Tweedy's lewisia (Lewisiopsis tweedyi) is a perennial herb that grows from a thick taproot. Evergreen fleshy leaves form a rosette or basal cluster from which arise multiples stems of 2?5 salmon, yellow-pink, or white flowers with 7-9 petals. This species is found in open coniferous forests on dry south-facing slopes, and on unforested sites between 1400 and 1650 metres in elevation.
Tweedy's lewisia (Lewisiopsis tweedyi) was designated as Endangered by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as it exists in Canada only in two small subpopulations and has declined 30% in recent years. The greatest threat is from recreational activities. It is not yet listed on Schedule 1 of the Species at Risk Act (SARA). In British Columbia, Tweedy's lewisia is ranked S1 (critically imperiled) by the Conservation Data Centre and is on the provincial Red list. The B.C. Conservation Framework ranks Tweedy's lewisia as a priority 1 under goal #3 (to maintain the diversity of native species and ecosystems). Recovery is considered to be biologically and technically feasible.
The population and distribution goal is to maintain stable or increasing populations throughout its range in British Columbia.
The following are the recovery objectives:
1.protect all known populations of Tweedy's lewisia throughout the B.C. range;
2.monitor trends in population size and distribution at all known locations; and
3.determine if it is feasible and appropriate to augment populations.
