The state of Colorado through the division assents to the provisions of the act of congress entitled "An Act to provide that the United States shall aid the states in wildlife restoration projects, and for other purposes.", approved September 2, 1937, and as amended. The division is authorized to perform such acts as may be necessary to conduct and establish cooperative wildlife restoration projects, as defined in such act, in compliance with such act and the rules and regulations promulgated by the secretary of the interior thereunder. No moneys or funds accruing to the division pursuant to such act shall be used for any purpose other than for such projects and the administration of the division, but the division may pay into the general fund as a part of its administrative costs a reasonable rental or service charge, as it may determine, for office quarters and auditing, bookkeeping, and like services furnished to the division by the state. All moneys now in the wildlife cash fund, or accrued or accruing to or received or receivable by the division, pursuant to such act shall be appropriated to pay for the administrative expense of such division for the protection, preservation, restoration, and control of wildlife of the state and to cover expenses in enforcing the wildlife laws of the state. Such moneys are to be expended upon a voucher approved by the director or an employee of the department authorized by the executive director and a warrant drawn by the controller.
