Requires the Department to support, promote, encourage, and facilitate the establishment of trail segments on State park lands and on lands of other federal, State, local, and private landowners. Provides that the requirement that additions be accompanied by adequate appropriations does not apply to this authorization but allows the State to receive donations of land and allows the purchase of other needed land with funds in the Clean Water Management Trust Fund, the Parks and Recreation Trust Fund, the federal land and Water Conservation Fund, and other available funding sources.
