Requires the department to prepare, maintain, and administer individual public motorized access plans for all public lands, other than aquatic lands, contained within each of the department's administrative units.

Requires the access plans to: (1) Estimate the number of miles of road or trail within each administrative unit that were open for public motorized access in 2003;

(2) Ensure that changes in road access within each administrative unit are implemented so that there is not a net loss of road or trail miles available for public motorized access within each administrative unit from the 2003 levels identified in the access plan; and

(3) Ensure that all future road or trail access closure decisions within an administrative unit are coupled by the opening of an equal number of road or trail miles for public motorized access within the same administrative district.

Requires the initial individual public motorized access plans for each administrative district to be completed by April 1, 2007, with implementation completed by August 1, 2007.
