USFWS determine threatened species status under the ESA for the bracted twistflower (Streptanthus bracteatus), a plant species from Texas. In addition, they designate critical habitat for the bracted twistflower. In total, approximately 1,596 acres (646 hectares) in Uvalde, Medina, Bexar, and Travis Counties, Texas, fall within the boundaries of the critical habitat designation. This rule applies the protections of the Act to this species and its designated critical habitat. They also finalize a rule issued under the authority of section 4(d) of the Act (a "4(d) rule") that provides measures that are necessary and advisable to provide for the conservation of this species. This rule is effective 11 May 2023. POC is Karen Myers, Field Supervisor, USFWS, Austin Ecological Services Field Office, 1505 Ferguson Lane, Austin, Texas; tele: 512–927–3500.
