Licenses under this subchapter shall be issued only when the applicant has produced evidence satisfactory to the Department that the proposed restricted game preserve will not conflict with any reasonable prior public interest and will, in the opinion of the Department, result in a general improvement in the quantity and quality of game in other areas of the State outside of the proposed restricted area, due to the travel and movement of game caused by the heavy stocking of the restricted area. In addition, in order to be eligible for a license, the proposed restricted area must contain contiguous lands under the same ownership, lease or management, aggregating not less than 300 acres, and no license shall be granted for reservations containing an aggregate of more than 1,000 acres, nor shall more than 5,000 acres in New Castle County be covered by such licenses at any one time. Moreover, the applicant must produce evidence satisfactory to the Department that there exists, or that the applicant will forthwith supply, sufficient cover and feed upon the property embraced by the application to adequately support game in numbers which, in the opinion of the Department, will be beneficial generally to other areas of the State outside of the reservation.
