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. Caliper measurements on nursery stock trees describe the size of the ...
Tree height is the vertical distance between the base of the tree and the highest sprig at the top of the tree. The base of the tree is measured for both height and girth as being the elevation at which the pith of the tree intersects the ground surface beneath, or "where the acorn sprouted."
However, as the tree is heavily buttressed, and irregular in shape, a calculation of nominal diameter, defined as the cross-sectional wood area expressed as a circle, gives this tree a diameter at breast height of 30.8 feet (9.4 m)—a much smaller number, but a more accurate representation of the tree's size.

Tree volume is one of many parameters that are measured to document the size of individual trees. Tree volume measurements serve a variety of purposes, some economic, some scientific, and some for sporting competitions. Measurements may include just the volume of the trunk, or the volume of the trunk and the branches depending on the detail ...
A trade gallon is a unit of volume for standard plant containers in the horticultural industries. It equals 3 US liquid quarts or 0.75 US gallons (2.8 L; 0.62 imp gal), [ 1 ] [ 2 ] [ 3 ] although some sources state that a trade gallon equals 2.7 litres (0.71 US gal).
The new year is always a good time to declutter and reorganize your home -- and you don't have to spend a lot of money to do it. While containers and organizers can get pricey at many retailers,...
American Forests, for example, uses a formula to calculate Big Tree Points as part of their Big Tree Program [3] that awards a tree 1 point for each foot of height, 1 point for each inch of girth, and 1 / 4 point for each foot of crown spread. The tree whose point total is the highest for that species is crowned as the champion in their ...
An analysis of data collected by the Native Tree Society (NTS), of over 1800 mature trees found, on average, the top of the tree was offset from the perspective of the surveyor by a distance of 8.3 feet (2.5 m), and therefore was offset from the base of the tree by around 13 feet (4.0 m). [17]
