Abstract
In 2000, the U.S. Forest Service (USFS), in cooperation with the Colorado State Forest Service, Denver Water, and other entities, implemented a program of forest thinning treatments to reduce the risk of large fires that could occur where surface fuels have accumulated and dense forest stands have resulted from past fire management activities. To assist in evaluating project effects over the short- and long-term, the USFS and Denver Water sponsored a pilot Hesperia skipper monitoring program for the federally threatened Pawnee montane skipper (PMS) (Hesperia leonardus montana), to evaluate the relative use by skippers of treated and untreated areas. Annual monitoring began in August 2000; this report discusses results of the most recent years monitoring in relation to all previous years.
