This report is the product of a project funded by the Northern Prairie Science Center of the National Biological Service, U.S. Department of Interior, under a cooperative agreement with Minot State University. Field work for the project was completed between May and August, 1995 and 1996. A primary objective of the project was production of a comprehensive, site-specific butterfly list that could serve as a basis for future monitoring of butterfly populations and as an aid in making management decisions for the area.
