Initiation of 5-Year Reviews of Seven Wildlife Species and Two Plant Species in the Mountain-Prairie Region

We, the U.S. Fish and Wildlife Service (Service), initiate 5- year reviews of seven wildlife species--Canada lynx (Lynx canadensis), grizzly bear (Ursus arctos horribilis) (as listed in the lower 48- States excluding the Greater Yellowstone Area population; see table 1), bonytail chub (=bonytail) (Gila elegans), humpback chub (Gila cypha), Colorado pikeminnow (=squawfish) (Ptychocheilus lucius), razorback sucker (Xyrauchen texanus), and Uncompahgre fritillary butterfly (Boloria acrocnema); and two plant species--Howellia aquatilis (water howellia) and Astragalus desereticus (Deseret milk-vetch)--in the Mountain-Prairie Region under the Endangered Species Act of 1973, as amended (Act). We conduct 5-year reviews to ensure that our classification of each species as threatened or endangered on the List of Endangered and Threatened Wildlife and Plants is accurate. A 5-year review is an assessment of the best scientific and commercial data available at the time of the review.
