Excerpt from Rapid Computation of Yield Tables for Managed, Even-Aged Timber StandsSample plots in stands that represent a wide range of densities, average diameters, and site qualities are measured to obtain a means of estimating periodic diameter growth. Plot trees are bored at breast height to determine radial wood growth. Data are obtained to relate diameter inside bark to diameter outside bark and vice versa. Periodic wood and bark growths are subtracted from present diameters to get diameters at the beginning of the period. Present and past diameters are grouped in stand tables, with diameters of recently dead trees added to the past stand tables. Present and past stand tables are used to compute present and past basal areas per acre and aver age stand diameters.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
