Conservation Issues

Habitat Large prairie dog complexes needed to support a black-footed ferret population do not currently exist in North Dakota. With widespread negative sentiment toward prairie dogs within the state it is uncertain whether prairie dog complexes would be allowed to expand sufficiently to support ferret reintroduction.
Other Natural or Manmade Factors Conversion of rangeland for agricultural uses is decreasing black-tailed prairie dog acres within the state, which in turn reduces potential black-footed ferret habitat.
