Nevada · Area of Critical Environmental Concern
Mormon Mesa
One of 2 areas BLM's Nevada office names Mormon Mesa; this one is 109,865 acres. All of them. BLM found a wildlife resource here, and its plan calls for special management. BLM's records place at least 9 mining claims BLM lists as Under Review and 7 rights of way inside the line today, and six grazing allotments cover part of it. It covers 109,865 acres and was designated September 19, 2000, in the 1998 Desert Tortoise amendment to Caliente MFP. In the plan's name, MFP stands for management framework plan.

Every area BLM's Nevada office holdsThe proposed rule
A proposed rule, RIN 1004-AF53, would change how BLM drafts every land use plan, and how it designates ACECs like Mormon Mesa. The comment window hasn't opened: the proposed rule wasn't in the Federal Register at our last check. The Watch sends one email the day it prints.
The rule's abstract
The purpose of this rulemaking is to establish in regulations an updated process for the approval of the development, revision, amendment, and maintenance of land use plans, as provided for by the Federal Land Policy and Management Act of 1976, for public lands administered by the Bureau of Land Management (BLM). Additionally, this rulemaking will provide clarification of the process the BLM uses for designating Areas of Critical Environmental Concern.Unified Agenda entry for RIN 1004-AF53, Publication ID 2026, reginfo.gov (OMB OIRA), read Oct 18, 2026
