About this file
This document contains a thinning inspection plot form used by the USDA Forest Service. The form collects data on tree counts, species, diameters, heights, and other stand information to evaluate pre-commercial thinning contract work. Key details include specifications for acceptable tree spacing, minimum and maximum diameters to cut, priority species, and categories to classify trees left standing that do not meet specifications. Additional notes sections allow recording of stand data such as average heights and diameters. The related federal contract opportunity is solicitation number 12970223R0023 for pre-commercial thinning services on the Hayfork Ranger District in California. The solicitation comes from the Department of Agriculture Forest Service.
