Area Of Influence
Areas Of Influence (AOI) identify areas where any project located within should consider potential effects to the Threatened, Endangered, Proposed, and Candidate species and designated and proposed Critical Habitat, in reference to Section 7 of the Endangered Species Act of 1973, as amended. AOI typically encompass larger areas than simply where the species is known to exist because of direct and indirect effects to the species and their habitat. It is important to consider potential effects to the species and their habitat within these larger areas. Action agencies are encouraged to refer to the Service’s Information, Planning, and Conservation System (IPAC) or contact the FWS Wyoming Ecological Services Office for additional information. (AOI boundaries based on the best available data at time of development. AOI will be updated as new information becomes available).
The greater sage-grouse (Centrocercus urophasianus) is a candidate for listing under the ESA (75 FR 13910, March 23, 2010). Please see our recent Federal Register notice for detailed information concerning the status of the species; this notice is available at http://www.fws.gov/wyominges/Pages/Species/Findings/GrtSageGrouse_CandidateBulletin.html. Greater sage-grouse are dependent on sagebrush habitats year-round. Habitat loss and degradation, as well as loss of population connectivity have been identified as important factors contributing to the decline of greater sage-grouse populations rangewide. Therefore, any activities that result in loss or degradation of sagebrush habitats that are important to this species should be closely evaluated for their impacts to sage-grouse.We recommend you contact the Wyoming Game and Fish Department to identify important greater sage-grouse habitats, recommended seasonal restrictions within the project area, and appropriate measures to minimize potential impacts from the proposed project. The Service recommends surveys and mapping of important greater sage-grouse habitats where local information is not available. The results of these surveys should be used in project planning to minimize potential impacts to this species. No project activities that may exacerbate habitat loss or degradation should be permitted in important habitats.
The State of Wyoming has adopted a “Greater Sage-grouse Core Area Protection” Executive Order 2010-4 to ensure greater sage-grouse conservation. The recommendations of the State Sage-grouse Implementation Team and State of Wyoming’s Greater sage-grouse “Greater Sage-grouse Core Area Protection” Executive Order 2010-4 state that development of any type in the identified core areas is done only when no decline to the species can be demonstrated. Executive Order 2010-4 further states the burden of proof for showing development does not affect sage-grouse rests with the industry or proponent in question, and any research they feel is necessary to convey this, should be conducted outside of core areas. If the proposed project is located in an area designated by the State of Wyoming as a core sage-grouse population area. We recommend you pursue additional consultation with the Wyoming Game and Fish Department on the core area strategy as it relates to this project.
