Lemmon's holly fern (Polystichum lemmonii) was designated by Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as threatened in Canada in May 2003, and listed on the federal Species at Risk Act (SARA) Schedule 1 in January 2005. Its current known Canadian range consists of a single disjunct population in south-central British Columbia. Lemmon's holly fern is an evergreen, perennial, tufted fern arising from a short, stout rhizome. This fern is restricted to ultramafic (high in iron and magnesium, low in calcium and nitrogen) soils throughout its entire range in western North America. In British Columbia, it occurs on two small, open, adjacent rocky ridges. Potential threats to the survival of the population include the degradation or destruction of the habitat through mining exploration and road construction for forest harvesting.
