(2) At any time the State Forester has reason to believe that forestland is not being managed as forestland, the State Forester shall review the owner's management plan, if any, and inspect the property. Subject to subsection (5) of this section, the State Forester shall advise the owner as prescribed in subsection (3) of this section if the State Forester determines the land is not being managed in accordance with a plan that provides for:

(4) The county assessor, upon receipt of the notice from the State Forester, shall cease to treat that land as forestland under ORS 321.257 to 321.390 and shall value the land as prescribed under ORS 308.146 and 308.232.

(5) If at the time that the State Forester views the land under subsection (3)(c) of this section, it is determined that a change in ownership has occurred, the State Forester shall notify the new owner as required under subsection (3) of this section in the manner of the original notification.

(6) When the owner of land disqualified from forestland assessment provides satisfactory information to the State Forester of subsequent action taken to correct the deficiency resulting in the disqualification of land, or provides an acceptable management plan to correct such deficiency, the State Forester shall so indicate to the county assessor. The assessor shall then assess the land under ORS 321.257 to 321.390, if the land is otherwise qualified for such assessment.

(7) The State Forester shall adopt rules necessary to carry out the purposes of this section.
