Species Profile for Uncompahgre Fritillary butterfly (Boloria acrocnema) Page 4 of 4 this pattern may be extended through 2011, and metamorphosing into an adult and reproducing in 2012. Very dry or very wet weather is suspected to be a factor in population changes, and may influence length of time to maturity, but no correlation to weather or other potential influences has been determined. The butterflies live as adults for only 1-2 weeks. Other The only observable current impacts are caused by relatively minor habitat degradation from hiking trail erosion, widening, and braiding on the edge of colonies at Mt. Uncompahgre and Redcloud Peak and short-term impacts from rapid sheep trailing/grazing through Mt. Uncompahgre. Neither of these actions occur at a level to be considered a threat to the species. Climate change has not been an observable threat to either the Uncompahgre fritillary butterfly or its habitat to date, but is a potential future threat that should be monitored. » Other Resources NatureServe Explorer Species Reports -- NatureServe Explorer is a source for authoritative conservation information on more than 50,000 plants, animals and ecological communtities of the U.S and Canada.
