((1)) During fiscal year 2012 and thereafter, the Secretary of the Interior shall accept the donation of any valid existing permits or leases authorizing grazing on public lands within the California Desert Conservation Area. With respect to each permit or lease donated under this paragraph, the Secretary shall terminate the grazing permit or lease, ensure a permanent end (except as provided in paragraph (2)), to grazing on the land covered by the permit or lease, and make the land available for mitigation by allocating the forage to wildlife use consistent with any applicable Habitat Conservation Plan, section 10(a)(1)(B) permit, or section 7 consultation under the Endangered Species Act of 1973 ( et seq.).
((2)) If the land covered by a permit or lease donated under paragraph (1) is also covered by another valid existing permit or lease that is not donated under such paragraph, the Secretary of the Interior shall reduce the authorized grazing level on the land covered by the permit or lease to reflect the donation of the permit or lease under paragraph (1). To ensure that there is a permanent reduction in the level of grazing on the land covered by a permit or lease donated under paragraph (1), the Secretary shall not allow grazing use to exceed the authorized level under the remaining valid existing permit or lease that is not donated.
