This plan provides a summary of what is known regarding the Harbison’s dun skipper, including life history, historic and current distribution, movement patterns, suitable habitat, and threats. A thorough understanding of the species is necessary to make appropriate adaptive management recommendations in an attempt to alleviate the current threats to the species. To develop this plan, we: 1. Reviewed existing data, including historic Harbison’s dun skipper locations, recent (2013-2017) survey data, property ownership to identify conserved lands for potential surveys, management, and acquisitions, and 2. Consulted with the wildlife agencies and other stakeholders to ensure that the most current information regarding Harbison’s dun skipper biology, management, regulations, conserved lands, and potential acquisitions were included.
