  1. What are some of the Major Silviculture Practices? AG-FS-7. The student will demonstrate the knowledge and skills necessary to evaluate and regulate timber stand growth for various forest objectives. Identify and prescribe major silvicultural practices for managing timber stand growth. B. Identify and prescribe harvesting practices for forest management.

  2. Silviculture • Application of various treatments such as tree planting, pruning, intermediate cuttings and harvest cuts • There are many factors to consider in selection of silvicultural treatments to meet your management objectives

  3. What are some different management objectives? • Timber production • Timber production/wildlife habitat • Timber production/watershed protection • Timber production/recreation areas • Aesthetics

  4. Why do we make intermediate cuts? • Intermediate cuts- cutting of timber at any time from the reproduction stage to timber maturity or final harvest • Improvement of existing stand • Regulation of tree and stand growth • Early financial returns • Reduction of condition favorable to insects and diseases • To create condition favorable to reproduction

  5. What are the methods of cleaning? • Cleaning- treatments in young stands, not past the sapling stage, to free the desired species from undesired species. • Prescribed burning • Basal spraying- spraying around the stump with herbicides to get rid of undesirable species • Foliage spraying • Cuttings

  6. What are the types of cuttings? • Improvement cuttings- cuts to improve stand competition, quality or condition • Sanitation cut- Removing trees infested with insects or attacked by diseases • Salvage cut- removes trees that are dead or damaged by insects, lightning, wind, etc. • Clear cutting- cutting all the large and small trees in a stand (everything) • Seed tree cutting- clear cutting all except 4-10 trees per acre for natural regeneration • Shelterwood cutting- cutting all trees except 25-60 mature cone-bearing trees for nat. reg. • Selection cutting- for uneven-aged stands; removing trees based on maturity, growth rate, diameter and vigor

  7. How do we determine the age and growth of a tree? • Increment boring allows one to determine relative age and growth rate of a tree

  8. Basal Area and Crown Length • Proper basal area for a stand of pines should range from 60-125 square feet per acre based on site index • Basal Area = (3.1416 x (DBH/2)2)/(144) OR • Basal Area = 0.005454 x DBH2 • Total Basal area= Total sq. ft. of trees in area/area of land • The proper crown length ratio for sapling size or larger trees is 1:3
