Species Profile

Dwarf Hesperochiron

Scientific Name: Hesperochiron pumilus
Taxonomy Group: Vascular Plants
COSEWIC Range: British Columbia
COSEWIC Assessment Date and Status Change: May 2019
COSEWIC Status: Endangered
COSEWIC Status Criteria: B1ab(iii)+2ab(iii); C2a(i); D1
COSEWIC Reason for Designation: This small, perennial plant is restricted to seasonally wet montane forest openings at four sites in a small area of southeastern British Columbia. The total number of mature individuals is very small (under 200). All Canadian sites are on Provincial Crown Land and potentially subject to logging of surrounding areas and/or road building activity with subsequent changes to site hydrology. Negative impact on the thin substrate by mountain-biking activity has been noted close to one occurrence. Competition from non-native plants, most notably Spotted Knapweed, is the most significant threat expected to lead to habitat degradation over time. Drought and atypically intensive natural fire, as per climate-change projections, could potentially damage or eliminate one or more occurrences within three generations.
COSEWIC History of Status Designation: Designated Endangered in May 2019.
SARA Status: No schedule, No Status
Date of Listing (yyyy-mm-dd):

No schedule - No Status

COSEWIC Status Reports

  • COSEWIC Assessment and Status Report on the Dwarf Hesperochiron (Hesperochiron pumilus) in Canada (2020-01-14)

    Dwarf Hesperochiron is a perennial, herbaceous plant that grows up to 10 cm tall from a slender stem connected to smaller offshoots by thin, fragile rhizomes. The generally hairless simple leaves grow in a basal rosette. There are from one to eight solitary, showy flowers per plant. The flowers are 1 to 3 cm wide, 5-lobed, with white petals and hairy, yellow throats. There are often striking purple markings on the petals. The fruits are oval capsules with many small seeds. Note: This COSEWIC assessment was received by the Minister on October 15th, 2018.

Response Statements

  • Response Statement - Dwarf Hesperochiron (2020) (2020-01-07)

    COVID-19 and the consultations on the listing of species at risk As a result of the ongoing COVID 19 situation, it is not possible to have in-person meetings. Taking this into consideration, please note that consultation closing dates have been set for both the Normal and Extended consultations for the terrestrial species considered in this document. We will work to ensure that all the known, potentially affected parties have the opportunity to contribute to the consultations and that the consultation process is flexible and sensitive to the current context. If you wish to contribute, please submit your comments by April 2, 2021 for species undergoing normal consultations and by September 2, 2021 for species undergoing extended consultations. You may provide comments by email, letters, or through the online survey.

Consultation Documents

  • Consultation on Amending the List of Species under the Species at Risk Act: Terrestrial Species January 2020 (2020-01-07)

    COVID-19 and the consultations on the listing of species at risk As a result of the ongoing COVID 19 situation, it is not possible to have in-person meetings. Taking this into consideration, please note that consultation closing dates have been set for both the Normal and Extended consultations for the terrestrial species considered in this document. We will work to ensure that all the known, potentially affected parties have the opportunity to contribute to the consultations and that the consultation process is flexible and sensitive to the current context. If you wish to contribute, please submit your comments by April 2, 2021 for species undergoing normal consultations and by September 2, 2021 for species undergoing extended consultations. You may provide comments by email, letters, or through the online survey. The Government of Canada is committed to preventing the disappearance of wildlife species at risk from our lands. As part of its strategy for realizing that commitment, on June 5, 2003, the Government of Canada proclaimed the Species at Risk Act (SARA). Attached to the Act is Schedule 1, the list of the species provided for under SARA, also called the List of Wildlife Species at Risk. Extirpated, Endangered and Threatened species on Schedule 1 benefit from the protection afforded by the prohibitions and from recovery planning requirements under SARA. Special Concern species benefit from its management planning requirements. Schedule 1 has grown from the original 233 to 622 wildlife species at risk. Please submit your comments by May 7, 2020, for terrestrial species undergoing normal consultations and by October 7, 2020, for terrestrial species undergoing extended consultations. For a description of the consultation paths these species will undergo, please visit the Species at Risk (SAR) Public Registry website at: The Minister of the Environment's Response to Species at Risk Assessments.
