¹E=Endangered, T=Threatened, PT=Proposed Threatened, S=Sensitive

²Each species indicated, if elevated to threatened or endangered, will be surveyed at each active quarry and prior to the activation of any future quarry.

³Reclamation will initiate Section 7 consultation for the Mohave population of the desert tortoise prior to the activation of any future quarry.

⁴Formal consultation is not requested on species in Mexico, because the action area under consideration is within the boundaries of the United States and the U.S. has no discretion regarding Mexico’s use of its Treaty water .
