The sites index included a short description and interpretation of each site, with bibliographical references and field observations.

Site trees are used to calculate the site index of the site in reference to a particular tree species.
13.
Site index has been the most widely used means of estimating site productivity in North America, despite some shortcomings.
14.
Tables were compiled of the relationships between different soils and different site indexes for important species of that area.
15.
Relative terms measure the density against a reference level, which is determined by dominant tree species, the plant community, and site index.
16.
In the United States, site index can be determined from soil maps provided by the Natural Resources Conservation Service ( NRCS ).
17.
A generalized model using both direct and indirect variables for developing composite site index equations was presented by Payandeh and Wang ( 1997 ).
18.
If the tree had any of these things happen to it the site index, which is derived from the site tree, value will be skewed.
19.
Direct methods of creating a site index include estimation from historical yield records, stand volume data, growth intercepts, or height age relationships ( site index ).
