Gratkowski, H. J. 1956. Windthrow around staggered-settings in old-growth Douglas-fir. Forest Science. 2(1): 60-74.
IN THE PAST DECADE, the patch-wise pattern of clear cinting. known as thestaggered-setting system has gained wideacceptance in the I)ouglas-fir forest of thePacific Northwest. Several advanta:(es anda few disadvantages arc claimed for thiscutting method in comparison with con-tinuous clear cutting (Aufder)teide, 19491.Orm major disadvantage of the staggered-setting system has proved to he windthrowof trees along the margins of the clear-emitunits. In some areas, the damage has seri-ously depleted many of the settings reservedfor later cutting, forcing changes in cutting.plans :11111 creating administrative problems.
This study has attempted to determinethe relative importance of sonic of the(actors which influence windthrOW ;11'01111ddr:11.-C111 settings in the Cascade Range.
