For <br />exanple, a 4C. stand becomes a 4B stand after a partial cutting. Therefore, in <br />acme cases it appears that there is more clearing with Alternative Three than <br />with Alternative Two. <br /> <br />:1 <br /> <br />Table IV-14 <br />ALTERNATIVE 'IW:) <br />TIMBER VOLUME RE/{()V1\JJ BY TYPE <br /> <br />16.9 <br />14.5 <br />10.3 <br /> <br />Total Total <br />~ ~ <br />8,627 4,326 <br />10,609 5,162 <br />556 278 <br />19,792 9,766 <br /> <br />~ <br /> <br />Acres <br />Cut Cords/Ac.
