A variable size plot is more dependent of the size of the trees. The tract is measured on a series of points and the trees are tallied for being in or out depending on their size and location relevant to the plot center. Usually an angle gauge, wedge prism, Tunagmetor, or Relascope are used to gather data for this type of plot. This allows for ...

Leitneria floridana (corkwood), the sole species in the genus Leitneria, is a deciduous dioecious shrub or small tree, found only in the southern United States states of Arkansas, Florida, Georgia, Missouri and Texas. It grows at damp habitats, mostly in coastal areas and has extremely light wood with a density less than that of cork. It ...
Proper use of angle gauge to count in trees Angle gauge indicating a tree to measure for a basal area factor of 10. An angle gauge is a tool used by foresters to determine which trees to measure when using a variable radius plot design in forest inventory. Using this tool a forester can quickly measure the trees that are in or out of the plot.
Tree girth measurement diagram. Tree girth is a measurement of the circumference of tree trunk. It is one of the most ancient, quickest, and simplest of foresters' measures of size and records of growth of living and standing trees. The methods and equipment have been standardized differently in different countries.
A tree caliper is a tool to measure the diameter of a tree. When used in forestry, the tree caliper tool measures the DBH or "diameter at breast height" of a tree that is growing in a landscape of any kind. The measurement is generally made at 4.5' or 1.4m above the soil.
The height of the tree is how high the tree goes up on the stick to a merchantable top. Tree height is measured to a merchantable top, the point at which a tree can be accepted for use by a sawmill. This point can be reached either by defects (extreme sweep, crook, deviating branching, or other defects) or at a diameter limit for very straight ...
The remaining part of the tree's diameter is for the back cut, which weakens the tree structurally enough for it to fall without splintering and other unwanted effects. There are three types of directional felling notches that are most commonly used in the logging and arboriculture industries by chainsaw operators.
