Abstract - Biological Assessment of the Wind Cave National Park Prarire Dog Management Program with Respect to the Endangered Peregrine Falcon
McClanahan, Lester F. 1981. Biological Assessment of the Wind Cave National Park Prarire Dog Management Program with Respect to the Endangered Peregrine Falcon. 3 p.
To offset what is viewed as an unnatural and unacceptable dominance by prairie dogs, of a limited prairie habitat type, the National Park Service proposes to initiate a prairie dog management program. Such a program, once begun, would entail periodic efforts to limit or reduce prairie dog colonies to levels believed necessary for maintenance of a balanced representation of a Northern Great Plains forest-prairie ecotone area.
Based on knowledge of: 1. the nature of teh toxicant proposed for the program, 2. the infrequency of surface kills, 3. feeding habits of the peregrine falcon, and 4. precautions to be taken, it is the Service's judgement that there will be no harmful effects to the endangered peregrin falcon. In addition it is felt that the nature and extent of the prairie dog management program is not of the magnitude to warrant preparation of an Environmental Impact Statement.
