Endangered and Threatened Wildlife and Plants; Initiation of 5-Year Reviews of 2 Species: Chihuahua Chub (Gila nigrescens) and Navasota Ladies'-Tresses (Spiranthes parksii)

Riepilogo

We, the U.S. Fish and Wildlife Service (Service) initiate 5- year reviews of Chihuahua chub (Gila nigrescens) and Navasota ladies'- tresses (Spiranthes parksii) under the Endangered Species Act of 1973, as amended (Act). The purpose of reviews conducted under section 4(c)(2)(A) of the Act is to ensure that the classification of species as threatened or endangered on the List of Endangered and Threatened Wildlife and Plants is accurate. The 5-year review is an assessment of the best scientific and commercial data available at the time of the review. Therefore, we are requesting submission of any new information (best scientific and commercial data) on Chihuahua chub and Navasota ladies'-tresses since their original listings as threatened in 1983 (48 FR 46053; October 11, 1983) and endangered in 1982 (47 FR 19539; May 6, 1982), respectively. If the present classification of either of these species is not consistent with the best scientific and commercial information available, we may recommend a change in Federal classification. A change would require a separate final rulemaking process.
