On an annual basis or as may be required, the executive officer of the conservancy shall report to the Director of General Services regarding privately owned properties within the conservancy's jurisdiction which have special significance and which might appropriately be the subject of trades for lands owned by the state for the purposes of preserving natural resources and moderating the impacts of regulation with the coastal zone.  A particular property shall be included in any report only upon agreement of the owner.
