  1. Cover in Percent Forestry Clipboard Tables Procedure – Forest Stand Stocking and Site Assessment • Compute average spacing and diameter-at-breast-height using zig-zag, fixed or variable plots for stand layers. • Determine desired “D+” spacing and desired spacing for each stand layer. • Continue and complete an environmental evaluation of all benchmark conditions. • Discuss management options and conservation treatment alternatives: • Forest stand enhancement – growth, thinning, harvest-reforestation, pests, aesthetics, wildlife, grazing, recreation • Marketing -- forest product types , mills, recreational and other opportunities • Access and erosion control -- access roads, trails and landings, cross-drain spacing , critical area planting • Wildfire risk reduction -- firebreaks, fuel breaks, forest slash treatment, integration of access roads and trails • Return to plots and mark/flag “leave” trees to demonstrate desired spacing. • Determine gross tree volumes to be removed, need for tree planting, pest management strategies, and other treatments indicated by the environmental evaluation. Initiate a conservation plan, contact the state forestry agency, and advise client on using consultants. 1 2 3 4 5 6 7 8 9 Common Forest Stand Layers or Strata 1 Main Stand Secondary Stand Secondary Stand Secondary Stand Main Stand Main Stand Understory Understory 3 2 4 5 6 NRCS-21Nov2006
