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 trees are chosen by what species is being grown in a particular forest. Different trees on the same site will produce different measurements of a site index. For example, a yellow-poplar (Liriodendron tulipifera) [2] growing on the same site as a white oak (Quercus alba) [3] will grow at a different rate over the same amount of time ...

Stand density index (SDI; also known as Reineke's Stand Density Index [1] after its founder) is a measure of the stocking of a stand of trees based on the number of trees per unit area and diameter at breast height (DBH) of the tree of average basal area, also known as the quadratic mean diameter. It may also be defined as the degree of ...
[1] [2] When taking forest inventory the following are important things to measure and note: species, diameter at breast height (DBH), height, site quality, age, and defects. From the data collected one can calculate the number of trees per acre, the basal area, the volume of trees in an area, and the value of the timber. Inventories can be ...
