Stand Examination
Today, the most common type of inventory is one that uses a random sampling technique which groups similar forests into one category based on age, stand structure, species, and location. The next step would be to begin from a random place and measure circular plots that are equidistant from one another. Inventory undertaken in conjunction with wildlife surveys has a regularized distance between plots. When taking inventory, a decision has to be made about which types of plots to measure. There are several different types of plots. The two most common types are fixed radius and variable radius, also known as prism radius. In a fixed radius plot, the forester finds the center of a plot and every tree within a certain fixed distance away from that point is measured. Variable radius plots are used more for inventory of volume. During this method, an angle is created and projected from the plot center and all trees that are larger than the projected angle are measured.

Famous quotes containing the words stand and/or examination:
“When we stand the truth on its head we generally fail to notice that our head is not standing where it should be standing either.”
—Friedrich Nietzsche (1844–1900)
“Maybe it’s understandable what a history of failures America’s foreign policy has been. We are, after all, a country full of people who came to America to get away from foreigners. Any prolonged examination of the U.S. government reveals foreign policy to be America’s miniature schnauzer—a noisy but small and useless part of the national household.”
—P.J. (Patrick Jake)
