NatureServe Conservation Status
Rounded Global Status Rank: T5 - Secure
Reasons: Although there may be far more than a thousand populations of this species throughout its extensive range, most are small, and Cypripedium parviflorum var. pubescens (Cypripedium pubescens), when treated taxonomically to exclude the more widespread var. makasin (as by Kartesz, 1999) is clearly vulnerable to habitat loss, horticultural collecting, and medicinal collecting rangewide. There are very few reports of large, demonstrably secure populations anywhere in North America. All reported populations contain less than 400 individuals, and most contain less than 30. There are numerous threats to this species and its habitats, and the typically small populations of this species are highly vulnerable to extirpation. Extirpation of two populations has been documented in Arizona, and it is likely that many others have been recently extirpated. Despite efforts to protect this species from collectors, it continues to be impacted by this practice. Though quantitative data is not available at this time, available information suggests that this species is still in decline, and further measures to protect it should be implemented.
