Description: The goal of delineating Conservation Opportunity Areas (COAs) was to use relevant variables to map areas in South Dakota where increased emphasis on habitat conservation, protection, or management will benefit rare species and remaining intact native habitats. Identified areas may include lands owned or managed by federal, state, tribal, or private entities and areas that may already be managed to maximize species and habitat diversity. The COA maps are not intended to display a land acquisition blueprint, but are an attempt to identify areas that would help fulfill the specific objectives for terrestrial and aquatic systems in South Dakota, as described in the Wildlife Action Plan.The Missouri River Gap Analysis Program (MOGAP) aquatic riverine classification hierarchy was adopted as the geographic framework for developing COAs. From this classification system, Aquatic Ecological System (AES)-Types were selected as the abiotic conservation targets in the selection process for identifying COAs. To fully address the biotic targets, aquatic SGCN were used as the primary focus within the COA selection process.Combinations of factors were used to develop a conservation strategy. This strategy was used to identify and map a statewide map of COAs that collectively represent all of the distinct riverine ecosystems within South Dakota and the full array of SGCN distributions.Basic Elements of the Conservation Strategy:• Develop separate COAs for each Ecological Drainage Unit (EDU);• Identify at least one COA for each AES-Type within each EDU;• When an EDU was composed of a single AES-Type, identify one COA for individual AESs representing separate stream classes (i.e. upper, middle, lower):o Upper: includes headwater, creek and small river stream classes.o Middle: includes headwater, creek, and medium or large river stream classes.o Lower: includes headwater, creek, and great river stream classes.Through this conservation strategy we provided an ecosystem approach to biological conservation and represented a wide spectrum of the diversity of macrohabitats across South Dakota. This strategy was developed to represent multiple populations for SGCN to select a wide range of COAs for protecting these species throughout South Dakota. We then established quantitative and qualitative assessment criteria for selecting COAs at the AES level.For additional information regarding COA Selection Criteria, please review Chapter 6.5 of the 2014 South Dakota Wildlife Action Plan found at http://www.gfp.sd.gov.
