Abstract
Site quality (SQ) is maximum timber a site can produce in a given year. Site quality evaluation is important tool for plantation management. Site factors decide the productivity of that site which varies with species. Though there are many direct and indirect methods for site quality evaluation, having their own advantages and limitations. Site index is most commonly and widely used in even aged forest. Intercept method has been used to determine site quality of young stands. For mixed and uneven-aged forests where determination of the age is quite subjective due to false annual growth site form method is used. RSI is new method of site quality evaluation based on self-thinning law. Site quality classification based on vegetational approach is found suitable in low latitudes. As productivity mainly derived by climate and soil environmental approach is also used. All the methods examined are reasonably accurate if applied to restricted areas. A carefully derived SI is the most accurate indirect method of SQ measurement. In this paper we will discuss various method for site quality measurement.
