Description: Describes changes in provisional tree grades for 351 young, mixed upland hardwood trees 6 years after thinning. Treatments of 30,50, and 70 percent stocking plus a crop-tree release were applied. Results indicate that light thinning and crop-tree thinning produced higher qualitjl and better grade trees than heavy thinning.

Keywords: stand density; thinning; stem quality; grade
