cases, it is attracted to sodium, resulting in attraction to human sweat. Historic and present range The Saint Francis' satyr was discovered in south-central North Carolina in 1980. Due to poaching and the lack of monitoring programs, many experts believed the species went extinct. Despite this, the species was rediscovered in 1992. Currently, the butterfly's range is completely isolated to the training fields of Fort Bragg, a military base in Cumberland and Hoke counties in North Carolina. Though Fort Bragg is the largest military installation in the world, the butterflies only occupy a 10 square kilometer (3.38 square mile) area on the base. Historically, several smaller subpopulations fell within the total range; currently, just a single metapopulation exists. The butterfly continues to be highly restricted in its distribution and has never been found outside of Fort Bragg. Habitat The Saint Francis' satyr's habitat is composed of wide, open grasslands; wetlands; and sedge-dominant ecosystems that experience regular natural disturbance. This disturbance is a result of beaver dam construction, natural fires, rainfall, or flooding. As a generally sedentary butterfly with delicate needs, it is imperative that these natural disturbances are maintained to create the habitat the butterfly needs to thrive. In addition to natural disturbances, the military operations at Fort Bragg create regular disturbances that help form wet meadows on the base. This habitat creation allows the Saint Francis' satyr population to be maintained at Fort Bragg. Present and historic population size Currently, not much is known about the butterfly's historic population size. From 2002 to 2005, the population size of the Saint Francis' satyr was estimated to be between 500 and 1400 butterflies. Usually small, their fragmented sites range from 0.2 to 2.0 hectares in size. Current numbers are estimated to be no more than 1000 individuals with no single population producing greater than 100 butterflies a year. The decrease in population size throughout the years could be a result of fire suppression and beaver extermination. Endangered Species Act listing history The butterfly was first listed under the Endangered Species Act in 1994, after threats of poaching and loss of habitat increased. Since its listing, there have been notable efforts towards preventing the collection of these butterflies. However, poaching is still a threat due to the butterfly's rarity. To combat this, any known listings of colony location sites are kept from the public record. Between 1998 and 2016, more than $3
