This simplified process allows you to get reasonably accurate gross volumes of timber but does not address net volumes, log grades, or monetary values. These estimates also can assist with financial analysis and the tax implications of a timber harvest.ĭon’t confuse this simplified process for collecting and analyzing a forest inventory with the more complex and precise techniques professional foresters use to estimate timber values for sales, land appraisals, or legal purposes. Estimates of volume and growth are helpful in planning when to harvest or how much to remove in a thinning operation.
#XSTAND NAXIMUM TREE DIAMETER HOW TO#
The step-by-step procedures in this publication show how to estimate standing volume and annual growth of individual timber stands that are relatively uniform in species, age, size, and density. If done correctly, this sampling process will give satisfactory results and save time and money. A more sensible alternative is to select an appropriate sample of trees that are representative of the entire stand, accurately measure that sample, and then use the information to estimate stand characteristics. However, this is impractical for even small acreages. How do you obtain this information? One approach is to measure every tree in the stand and add it all up. An accurate estimate of these parameters helps answer important management questions: Do I have too few trees? Too many trees? Are my trees growing well? How much volume is in my trees? Whatever your objectives, sound forest management plans require a thorough inventory: basic information such as tree size, species, density, growth rates, and merchantable volume. Woodland owners value their lands for many reasons, including aesthetics, privacy, recreation, fish and wildlife, income, and more.
