Measuring Site Index
Site index (SI) is a measurement commonly used by foresters to describe the productivity of a site. Typically this measurement is used to describe sites growing well-stocked even-aged forests. Site index is the average height of the dominant1 and codominant2 trees on the site, at a given age (base age). Typically, the base age for hardwoods and white pine in Virginia is 50 years, while the base age for loblolly pine is 25 years. For example, a SI of 75, base age 50, means that the average height of the dominant and codominant trees on a site will be 75 feet when they are 50 years old (SI50=75). The higher the SI, the higher the site productivity (trees will grow faster than on a site with a lower SI).

Forest Landowner’s Guide To The Measurement Of Timber And Logs
As a forest landowner interested in selling timber, you are naturally interested in the price you will receive for your product and how that price is determined. The measurement of standing timber and logs may seem strange and complicated to you, and it is possible that you may be quoted dramatically different prices based upon differing estimates of the amount of timber you have and the units of measurement used. Methods of measuring timber and the units of measurement often differ between buyers, and, as a seller, you should have an understanding of these methods, the units of measurement, and an idea as to a reasonable price for your timber.
