This scale gives the tree height in feet directly when measured at a distance of 100 feet (30 m) from the tree. In general, the clinometer is used to measure the angle Θ from the eye to the top of the tree, and then the horizontal distance to the tree at eye level is measured using a tape.
Errors associated with this mistake may yield measurements that are off many tens of feet and some errors of over forty feet and more have made it onto various champion tree lists, and in at least two cases, the errors have exceeded 60 feet. [15] [16] Sine height measurement. A third remote method is called the sine-height method or ENTS method.
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 ...
In atmospheric, earth, and planetary sciences, a scale height, usually denoted by the capital letter H, is a distance (vertical or radial) over which a physical quantity decreases by a factor of e (the base of natural logarithms, approximately 2.718).
For example, the Middleton Live Oak (Quercus virginiana), height 67.4 feet, dbh 10.44 feet, crown spread 118 feet) was found to have a trunk volume of 970 ft 3 (24.5 m 3) and a branch volume of 3,850 ft 3 (109 m 3) [15] The branch volume was almost 4x that of the trunk.

Site index is used to measure the productivity of the site and the management options for that site and reports the height of dominant and co-dominant trees in a stand at a base age such as 25, 50 and 100 years. [2] For example, a red oak with an age of 50 years and a height of 70 feet (21 m) will have a site index of 70. Site index is species ...
