GUIDELINES FOR USING UPLAND HARDWOODS STOCKING GUIDE ANDYIELD TABLES
The oak-hickory forest type is the most prevalent of the upland hardwood types. The oaks aremost abundant in this type, usually occupying dominant and co-dominant positions within thestand. The oaks are favored for management in the oak-hickory type as well as being highlyfavored in the other mixed-hardwood types. These guidelines assume intensive management ofwell-stocked stands with periodic thinning. Thinning throughout the rotation will be frombelow, leaving the best crop trees until the final harvest. Individual trees can be grown tolarger diameters in less time by the use of well planned thinning operations, thus producing ahigher quality product in a shorter rotation period.

Basically, two stand condition classes should be considered. The first assumes the availabilityof even-aged stands of various ages that contain levels of growing stock, which adequatelyoccupy the site. The second condition assumes that growing stock levels are below that whichwould allow the stand to be carried at satisfactory stocking and must be regenerated. Becauseof the past �high grading� cutting practices or wildfires, many upland hardwood stands areunder-stocked with desirable trees, contain many �cull� trees and need regeneration. SeeSection IV � Technical Guide Code 666, Forest Stand Improvement; and Code 490, FORESTSITE PREPARATION.

Gingrich�s stocking guides (below) are used to determine whether existing stands have (1) sufficientbasal area in growing stock trees to carry through rotation, or (2) whether the stands should beregenerated.
The C level of stocking is used as a minimum of basal area required to carry existing stands. Standsat the C level of stocking will fully occupy the site in an average of 10 years and are worth saving.Thinning would not be carried out unless the stocking of desirable trees is above the B level, whichis near 60 percent of full stocking. This means that total basal area would need to be substantiallyabove the residual B-level shown on the tables for existing stands before thinning to this level wouldbe practical. The key to using this growth and yield data is the appraisal of stocking conditions andthe use of subsequent cultural treatments to maximize growth and quality of growing stock trees, andthus maximize rates of returns from investments. This depends on the skill of the user in classifyinggrowing stock trees and stand conditions. Do not count cull trees or unacceptable species in basalarea.
The standards used to determine growing stock trees are critical. The time to begin thinning inyoung stands is also important because early investments must be carried for a long period.Thinning should be delayed until trees capable of maintaining dominant crown positions can beidentified in the stand. Research indicates that attempts to pre-commercially thin before this naturalselection takes place usually result in wasted money and effort.
