Vulnerability or Rocky tundra is somewhat vulnerable to some recreation activities (trails and Modification routes), and these habitats would be difficult to revegetate. But the habitat is also somewhat resilient to disturbance. Effects on the species itself are not known. Tonestus pygmaeus is probably not palatable to wild or domestic herbivores.

Taxonomy. Should be called Tonestus pygmaeus, rather than Haplopappus pygmaeus. This is considered to be a valid species by all botanists, endemic to Colorado, southern Wyoming, and northern New Mexico, with disjunct populations in southwestern Montana. Discussion. Based on distribution and abundance, and its habitat in rocky sites, this species probably does not have great concerns for viability. Any concerns would probably better be handled by improved management of Alpine zone. References Albee, Beverly J.; Leila M. Shultz; and Sherel Goodrich. 1988. Atlas of the Vascular Plants of Utah.
