Reasons: Mahonia aquifolium is native and relatively common in western North America, from Alberta south through California into northern Mexico. Roots, stem, and leaves of this species are wild-collected for medicinal use and are traded in the medicinal, herbal, and landscaping markets. M. aquifolium is reportedly used as a substitute for an herb that is heavily commercially traded. It is also the preferred species in this genus for commercial collection due to its large root size. This species may be threatened over time by increased interest in its medicinal properties if wild-collection is not monitored.
