Two basic methods are available for their construction, diameter class (or stand table) projection and cohort modelling. Individual yield tables are specified by a combination of tree species, yield class and management prescription. Managed stand yield tables describe the physical development of treated forests in quantitative units familiar to the planner, silviculturist, economist, protection specialist, and others responsible for implementing and assessing intensive forestry practices.

The developed forest biomass yield tables indicated that the unutilized wood biomass due to defects accounted for the largest part of the whole unutilized wood biomass, and that the ratio of unutilized parts in stem volume to total stem volume could vary with stand age and site productivity class.

Constructing a yield table for smallholder forests in Leyte is more challenging because there are few old plantations, and because the large range of site (e.g., geology, These slides are expected to be useful for the students and persons who are preliminary 3.2.1 Types of yield prediction models. Stand density, in turn, is taken to be a function of site quality, age, and an initial measure of stand density. All the decision trees that make up a random forest are different because each tree is built on a different random subset of data.

However, sustainability of timber products can be associated with uneven-aged forests as well. Normal-stand tables are frequency distributions of tree stems by diameter classes within stands of given age and site quality. A normal-yield table is a tabulated statement of yields to be ex- pected from well-stocked, even-aged stands of a given timber type, at successive ages, for the range of site qualities characteristic of the type.
