• Abstract:
  The grasslands of Nebraska are highly altered due to anthropogenic development and ; degradation. The loss and degradation of grasslands has significantly impacted populations of ; swift fox (Vulpes velox), a Nebraska Natural Legacy Plan Tier‐1 at risk species. We began a ; project to document the occurrence of swift fox in Nebraska and identify the anthropogenic and ; ecological factors that limit swift fox distribution through the development of a species ; distribution model. Over two years we conducted four surveys on 200 public and private sites ; within Western Nebraska. From nearly 5 million images representing 22,670 trap nights, we only ; detected swift fox on roughly 3.5% of our surveys. Although we were able to make a visual ; model of the estimated distribution of swift fox in Nebraska, the low numbers of presence data ; resulted in a model that performed poorly in predicting swift fox habitat suitability. Because ; swift fox are a species of concern, errors of omission are extremely important, and therefore we argue ; that predicted distribution map should interpreted and used cautiously.
