Pawnee Montane Skipper

The Pawnee montane skipper habitat has been threatened by the proposed Two Forks dam and reservoir which would have inundated and destroyed 22% of the skipper’s habitat with an estimated loss of 23-42% of the population.

Poweshiek Skipperling

Poweshiek skipperling butterfly populations have shown a well-documented collapse in less than a decade between 2000 and 2010, with likely extirpation of over 95% of the populations. In 2000, Poweshiek skipperling was known from native prairie remnants in Iowa, Minnesota, North and South Dakota, and Wisconsin and in fens in Michigan. By 2010, it was no longer found in the Dakotas, Minnesota, and Iowa. The original core habitat range for the species was orders of magnitude larger than the current range. The cause of this wide-spread decline is still unknown.
