Overstory Removal

4.9/5 (12389 ratings)

Description:Overstory removal can offer economic and esthetic advantages over clearcutting and regeneration, but projecting success is difficult. Twenty-nine units on nine operational overstory removal cuts in northern California were studied to determine what factors are related to satisfactory or unsatisfactory stocking after harvest. Stocking determinations were based on number of trees meeting minimum crop tree standards. Although all of the postharvest stands contained adequate numbers of trees, only about half passed minimal stocking standards based on number of trees meeting crop tree criteria. Only 2 of 11 preharvest stand characteristics tested were sufficiently associated with postharvest condition to be identified in discriminant analysis. The two characteristics were arithmetical average diameter at breast height of the overstory and total longitudinal cross-sectional area of the overstory trees. These two variables correctly identified postharvest stands as stocked 83 percent of the time and as unstocked 77 percent of the time, based on preharvest conditions.We have made it easy for you to find a PDF Ebooks without any digging.
