(1) When the board or department issues a lease or license on property upon which a lease or license of a different type already exists, the existing lessee or licensee shall be compensated by the more recent lessee or licensee for damages to the crops, improvements or leasehold interest of said existing lessee or licensee. Lessees or licensees may not receive compensation for such damages in excess of the value of actual damages to the crops, improvements or leasehold interest of said existing licensee. Only in exceptional cases documented to and approved by the department may the lessee or licensee receive damages for natural resources or crops in excess of the annual rate that the lessee or licensee is making to the department for rental payments. If a lessee or licensee collects or attempts to collect an amount in excess of said actual damages, such action may constitute sufficient grounds for cancellation of the lease or license. The department may adjust the A.U.M.'s allocated to a grazing lease or license when there is issued a lease or license for another purpose and that other purpose interferes with the grazing on the state lease.
