Global Short Term Trend: Decline of 10-30%
Comments: The habitat of Cypripedium parviflorum var. pubescens has certainly declined since European settlement of North America began. Forests have been cut. Wetlands have been drained. It is likely that Cypripedium parviflorum var. pubescens has incurred simultaneous population loss, the amount of which partly reflecting the localized habitat losses. It is likely that populations have been and continue to be impacted, at least locally, by collectors for the plant trade and by gardeners. This species was reportedly far more abundant historically in northeastern South Dakota (David Ode pers. comm.).
