Arizona · Area of Critical Environmental Concern
Lone Butte
BLM found a natural system, a cultural value and a scenic value here, and its plan calls for special management. BLM's records place no claim, lease or right of way inside the line today, and a grazing allotment covers part of it. It covers 1,759 acres and was designated January 29, 2008, in the Arizona Strip Field Office RMP and ROD. In the plan's name, RMP stands for resource management plan and ROD for record of decision.
One of the 1,120 places the Bureau of Land Management has designated an Area of Critical Environmental Concern. This page shows its line, what BLM found there and what sits inside it.

Every area BLM's Arizona 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 Lone Butte. 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
