There are 16 occurrences known, and about 6 are of good viability. This is a locally common, narrow endemic of the drainages and main canyon of the Arkansas River in central Colorado (a range only about 40 km long). Threats to the species include recreational use of habitat, highway construction and maintenance and, residential/vacation home development.
Possible rerouting of US Highway 50 might affect known populations (Von Bargen 1997).
Only one known population (Von Bargen 1997).
There is no formal management plan.
Research needs include understanding this species reproductive biology and ecology, habitat requirements and population dynamics.
