Amends the Forestry Development Act. Specifies that, before the Department of Natural Resources may approve a forest management plan under the Act, the timber grower must obtain approval of the plan from the corporate authorities of the municipality in which the affected land is located or, in the case of land located in an unincorporated area, from the county board. Provides that the Department may not approve a proposed forest management plan unless and until it receives a resolution or ordinance from the corporate authorities of the municipality or county, as the case may be, assenting to the adoption of the plan. Specifies that these requirements also apply to reapprovals of forest management plans.
