Book Description
Excerpt from Measuring the Forest Crop It is not, however, the measuring of the cut wood that we propose to discuss here, but the measuring of the standing crop as it is found in the forest. This knowledge, not only of what amount of wood is stand ing on an acre at a given time, but what amount grows in a year or has grown in a given period, is of great importance with a crop which requires many years to mature, and does not, like a field crop, have a definite period when it is ripe, but with which the harvest depends on the question when it is profitable to cut the crop. The amount which grows each year varies at different periods of the life of the crop, hence if we want to determine when it is most profitable to cut the crop we must be able to measure its growth and to determine whether the yearly or periodic increment is such as to make it desirable to let the crop stand because it increases in value in due proportion to the cost of its standing, or to cut it because the wood made per year ceases to pay interest on the cost. In order to measure the amount of timber standing and the amount of wood growing we must know the methods of measuring (1) the contents of a single tree; (2) the contents of a stand of trees or grow in g stock; (3) the rate at which single trees and whole stands grow under varying conditions and at various ages. While full knowledge of the subject may be acquired only by special study and application, familiarity with the simplest method is within the easy reach of everyone interested or engaged in lumbering or forestry operations, and only the simplest methods are to be discussed here.
