The small forestland owner office may contract with private consultants that the office finds qualified to perform timber cruises of forestry riparian easements or to lay out streamside buffers and comply with other forest practices regulatory requirements related to the forestry riparian easement program. The department shall reimburse qualifying small forestland owners for the actual costs incurred for laying out the streamside buffers and marking the qualifying timber once a contract has been executed for the forestry riparian easement program. Reimbursement is subject to the work being acceptable to the department. The small forestland owner office shall determine how the reimbursement costs will be calculated.
