The greatest threat to the species is from overcollecting. The Uncompahgre fritillary butterfly lives in patches of snow willow at high elevations, and has very limited habitat, a small population size, and low genetic variability, which may affect long-term population stability. The species is susceptible to trampling by recreationists and grazing animals.
Population monitoring has been conducted for 5 years (through 1992) at the two known colony sites. Preliminary reports indicate that the 1992 population of the Uncompahgre fritillary butterfly has increased slightly from previous years. Studies to determine climatological effects on the species and its habitat have been conducted, as well as research on reproductive biology, larval development, and host plant-butterfly interactions. Long-term studies to improve management of the butterfly also are under way. In addition, prohibitions on collection of the species are being enforced.
Necessary recovery actions include restricting collection of the butterfly, monitoring known populations and searching for new ones, and continuing data collection to determine if there are any other threats to the species.
Forest Service and Bureau of Land Management: The Forest Service and the Bureau entered into an interagency agreement with the Fish and Wildlife Service in 1992 to conduct long-term studies of the butterfly. The Forest Service and the Bureau have responsibilities to conduct surveys for new colonies, carry out law enforcement activities, continue population monitoring, and, if determined to be necessary, implement reintroduction.
The Colorado Natural Areas Program: The Colorado Natural Areas Program has provided a person to participate on the recovery team for the butterfly.
