Site index of Delaware-Maryland sweetgum stands in relation to soil characteristics

Abstract

Intensive forest management requires knowledge about the differences in productivity of land areas or sites. The suitability of management systems and stand treatments often depends on the potential of the particular site in question. For example, conversion of low-value stands to another species may be economically feasible on the best sites, but not on the poor ones. To provide the guides needed for management decisions, sites must be grouped into quality classes on the basis of studies that relate site productivity to measurable site characteristics. Local studies are usually required, because factors important in one region often prove to be relatively unimportant in another.
