California · Area of Critical Environmental Concern
Desert Lily Preserve
BLM found a natural system, a scenic value and a natural process here, and its plan calls for special management. Nothing that BLM's records place sits inside the line today. It covers 2,059 acres and was designated September 14, 2016, in the CDCA Plan, as amended by DRECP. In the plan's name, CDCA stands for California Desert Conservation Area and DRECP for Desert Renewable Energy Conservation Plan.
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 California 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 Desert Lily Preserve. 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
