Site index is a term used in forestry to describe the potential for forest trees to grow at a particular location or "site". Site is defined as "The average age of dominate and/or codominate trees of an even-aged, undisturbed site of intolerant trees at a base age"; [1] furthermore, the word site is used in forestry to refer to a distinct area where trees are found. [2]
Site tree refers to a type of tree used in forestry, which is used to classify the quality of growing conditions trees at a particular forest location. A site tree, is a single tree in a stand (group of growing trees) that gives a good representation of the average dominant or co-dominant tree in the stand.
Site index – a species specific measure of site productivity and management options, reported as the height of dominant and co-dominant trees in a stand at a base age such as 25, 50 and 100 years; Tree taper – the degree to which a tree's stem or bole decreases in diameter as a function of height above ground. So it can be sharp or gradual.

The California Department of Forestry and Fire Protection, colloquially known as Cal Fire, [3] is the fire department of the California Natural Resources Agency in the U.S. state of California. It is responsible for fire protection in various areas under state responsibility totaling 31 million acres, as well as the administration of the state ...
The largest forest entirely within the state is Shasta-Trinity National Forest, at 2,209,832 acres (8,942.87 km 2), the smallest is Cleveland National Forest at 460,000 acres (1,900 km 2). The Lake Tahoe Basin Management Unit is not precisely a national forest in the conventional sense. Instead the Forest Service manages the land with ...

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]
