To provide national forest grazing permittees means for the expression of their recommendations concerning the management and administration of national forest grazing lands, a local advisory board shall be constituted and elected as hereinafter provided for each national forest or administrative subdivision thereof, whenever a majority of the grazing permittees of such national forest or administrative subdivision so petitions the Secretary of Agriculture. Each elected local advisory board existing for such purpose on April 24, 1950, and recognized as such by the Department of Agriculture, shall continue to be the local advisory board for the unit or area it represents, until replaced by a local advisory board or boards constituted and elected as hereinafter provided.

Each such local advisory board shall be constituted and elected under rules and regulations, consistent herewith, now or hereafter approved by the Secretary of Agriculture, and shall be recognized by him as representing the grazing permittees of the national forest or administrative subdivision thereof for which such local advisory board has been constituted and elected.

Each such local advisory board shall consist of not less than three nor more than twelve members, who shall be national forest grazing permittees in the area for which such board is constituted, elected, and recognized. In addition, a wildlife representative may be appointed as a member of each such board by the State game commission, or the corresponding public body of the State in which the advisory board is located, to advise on wildlife problems.

Each such local advisory board shall meet at least once annually, at a time to be fixed by such board, and at such other time or times as its members may determine, or on the call of the chairman thereof or of the Secretary of Agriculture or his authorized representative.

At least thirty days prior to the issuance by the Secretary of Agriculture of any regulation under sections 490, 500, 504, 504a, 555, 557, 571c, 572, 579a, 580c to 580l, and 581 1 of this title or otherwise, with respect to the administration of grazing on national forest lands, or of amendments or additions to, or modifications in, any such regulation, which in his judgment would substantially modify existing policy with respect to grazing in national forests, or which would materially affect preferences of permittees in the area involved, the local advisory board for each area that will be affected thereby shall be notified of the intention to take such action. If as a result of this notice the Secretary of Agriculture shall receive any recommendation respecting the issuance of the proposed regulation and shall overrule, disregard, or m

odify any such regulations, he or his representative shall furnish in writing to the local advisory board his reasons for such action.

Any such local advisory board may at any time recommend to the Secretary of Agriculture, or his representative, the issuance of regulations or instructions relating to the use of national forest lands, seasons of use, grazing capacity of such lands, and any other matters affecting the administration of grazing in the area represented by such board.
