Growth is a biological process, which applies to the organism in its entirety, including all tree components (stem, branches, roots, foliage). Increment expresses the observed growth of the organism during a given period of time and normally applies to the tree and stand variables diameter, basal area, height, volume, and biomass. Yield is defined as the harvested or harvestable accumulated increment per unit area. Review journals are the evaluation of work by one or more people with similar competences as the producers of the work (peers). It functions as a form of self-regulation by qualified members of a profession within the relevant field. Peer review methods are used to maintain quality standards, improve performance, and provide credibility.
