2. Tree girth measurement - Wikipedia

   en.wikipedia.org/wiki/Tree_girth_measurement

   In this case a better option would be to measure the standard girth measurement at 4.5 feet above ground level on the high side of the tree and note this in the measurement description [13] [17] The height of this measurement point above the standard base point at midslope should also be noted. If measuring a mountaintop forest of stunted trees ...

3. Tree height measurement - Wikipedia

   en.wikipedia.org/wiki/Tree_height_measurement

   Additional details on the methodology of tree girth measurement, tree crown measurement, and tree volume measurement are presented in the links herein. 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 (2.54 ...

4. Tree measurement - Wikipedia

   en.wikipedia.org/wiki/Tree_measurement

   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."

5. Forest inventory - Wikipedia

   en.wikipedia.org/wiki/Forest_inventory

   Diameter at breast height (DBH) – measurement of a tree's girth standardized with different countries having different standards they are often at 1.3 meters (about 4.5 feet) above the ground; Form factor – the shape of the tree, based on recorded trees and commonly then given for calculating tree volumes for a given species.

6. Tree crown measurement - Wikipedia

   Additional details on the methodology of tree height measurement, tree girth measurement, and tree volume measurement are presented in the links herein. 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 ...

7. Stocking (forestry) - Wikipedia

   en.wikipedia.org/wiki/Stocking_(forestry)

   When stocking, a tree's basal area is measured. The basal area is a cross-sectional area of the stump taken about 4.5 feet (1.4 m) above the ground. [7] The equation for calculating the basal area of trees in a stand is Basal Area = 0.005454 DBH 2, where DBH is the diameter of the tree at the aforementioned measuring height. [7]

8. Dendrometry - Wikipedia

   en.wikipedia.org/wiki/Dendrometry

   Dendrometry is the branch of forestry that is concerned with the measurement of the various dimensions of trees, such as their diameter, size, shape, age, overall volume, thickness of the bark, etc., as well as the statistical properties of tree stands, including measures of central tendency and dispersion of these quantities, wood density, or yearly growth, for instance.

9. Biltmore stick - Wikipedia

   en.wikipedia.org/wiki/Biltmore_stick

   The bottom of the stick should line up with the bottom of the tree's trunk. 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 ...
