Numerous studies have demonstrated that using ecological models is beneficial in recovering species listed under the Endangered Species Act (ESA). In addition, many federal agencies and environmental organizations have recommended using strategic approaches to conservation. One rare species in need of conservation is the American burying beetle (ABB, Nicrophorus americanus). The ABB was listed as endangered in 1989 and conservation efforts need to be targeted and improved to be successful in achieving de-listing. We combined presence/absence ABB surveys (1979-2011), with habitat-based model projections, to identify specific habitats where the ABB is likely to occur. Our habitat based range for the ABB was 96.9% accurate in identifying positive ABB surveys (n=485) from 1979 to 2011. Previously, potential ABB habitat was identified using political or county boundaries and was not precise and also included areas that were unsuitable for ABB habitat. Using spatial data, known locations, and model projections, we reduced the potential habitat range by over 4.5 million acres (1.8 million hectares) from the county delineation, resulting in greater precision for conservation of the ABB, more targeted conservation efforts, and reduced costs to other federal agencies and industry that are required to have minimal impact to this endangered species under the ESA. Our approach will be useful to other agencies and other states that need to target conservation and recovery efforts for rare invertebrates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
