Summary

The Secretary of the Interior must manage the Las Cienegas National Conservation Area to protect, conserve, and improve its natural and cultural resources under federal land laws. Only activities that support the area's purposes (as listed in the law) are allowed. Grazing is allowed if it follows all laws and rules. Motorized vehicles can be used only for administration or emergencies, or on roads and trails specifically allowed: before a new management plan takes effect, only on routes shown for motor use in the plan that applied on December 6, 2000; after a new plan takes effect, only on routes that plan allows. The FAA approved restricted military airspace (Areas 2303A and 2303B) before December 6, 2000, and the conservation designation does not change military flight restrictions or stop the military from asking the FAA for new or changed restricted airspace. Hunting is allowed under U.S. and Arizona laws, though the Secretary can, after talking with Arizona’s wildlife agency, set no-hunting zones or times for safety or public use. The Secretary may act to prevent major fires, insect outbreaks, or disease. No buffer zones around the area will be created, and uses outside the area that are not allowed inside may continue up to the boundary. Except for valid existing rights, all federal lands inside the Conservation Area and any lands the United States later acquires there are withdrawn from public land entry, mining claims, and mineral or geothermal leasing under the relevant laws. The Secretary must allow reasonable access to privately owned lands inside the area and must respect valid existing rights-of-way.

(a)The Secretary shall manage the Conservation Area in a manner that conserves, protects, and enhances its resources and values, including the resources and values specified in section 460ooo–3(a) of this title, pursuant to the Federal Land Policy and Management Act of 1976 (43 U.S.C. 1701 et seq.) and other applicable law, including this subchapter.
(b)The Secretary shall allow only such uses of the Conservation Area as the Secretary finds will further the purposes for which the Conservation Area is established as set forth in section 460ooo–3(a) of this title.
(c)The Secretary of the Interior shall permit grazing subject to all applicable laws, regulations, and Executive orders consistent with the purposes of this subchapter.
(d)Except where needed for administrative purposes or to respond to an emergency, use of motorized vehicles on public lands in the Conservation Area shall be allowed only—
(1)before the effective date of a management plan prepared pursuant to section 460ooo–5 of this title, on roads and trails designated for use of motorized vehicles in the management plan that applies on December 6, 2000; and
(2)after the effective date of a management plan prepared pursuant to section 460ooo–5 of this title, on roads and trails designated for use of motor vehicles in that management plan.
(e)Prior to December 6, 2000, the Federal Aviation Administration approved restricted military airspace (Areas 2303A and 2303B) which covers portions of the Conservation Area. Designation of the Conservation Area shall not impact or impose any altitude, flight, or other airspace restrictions on current or future military operations or missions. Should the military require additional or modified airspace in the future, the Congress does not intend for the designation of the Conservation Area to impede the military from petitioning the Federal Aviation Administration to change or expand existing restricted military airspace.
(f)Nothing in this subchapter shall affect valid existing rights-of-way within the Conservation Area. The Secretary shall provide reasonable access to nonfederally owned lands or interest in lands within the boundaries of the Conservation Area.
(g)Hunting shall be allowed within the Conservation Area in accordance with applicable laws and regulations of the United States and the State of Arizona, except that the Secretary, after consultation with the Arizona State wildlife management agency, may issue regulations designating zones where and establishing periods when no hunting shall be permitted for reasons of public safety, administration, or public use and enjoyment.
(h)Nothing in this subchapter shall preclude such measures as the Secretary determines necessary to prevent devastating fire or infestation of insects or disease within the Conservation Area.
(i)The establishment of the Conservation Area shall not lead to the creation of protective perimeters or buffer zones around the Conservation Area. The fact that there may be activities or uses on lands outside the Conservation Area that would not be permitted in the Conservation Area shall not preclude such activities or uses on such lands up to the boundary of the Conservation Area consistent with other applicable laws.
(j)Subject to valid existing rights all Federal lands within the Conservation Area and all lands and interest therein which are hereafter acquired by the United States are hereby withdrawn from all forms of entry, appropriation, or disposal under the public land laws and from location, entry, and patent under the mining laws, and from operation of the mineral leasing and geothermal leasing laws and all amendments thereto.
