No land conveyed to a Native Corporation
pursuant to this chapter or by operation of the Alaska National Interest Lands Conservation Act
which is within a contingency area
designated in a timber sale contract let by the United States
shall thereafter be subject to such contract or to entry or timbering by the contractor. Until a Native Corporation
has received conveyances to all of the land to which it is entitled to receive under the appropriate section or subsection of this chapter, for which the land was withdrawn or selected, no land in such a contingency area
that has been withdrawn and selected, or selected, by such Corporation under this chapter shall be entered by the timber contractor and no timber shall be cut thereon, except by agreement with such Corporation. For purposes of this subsection, the term “contingency area”
means any area specified in a timber sale contract as an area from which the timber contractor may harvest timber if the volume of timber specified in the contract cannot be obtained from one or more areas definitely designated for timbering in the contract.
