Timber Stand Improvement

  1. 1. Timber Stand Improvement
  2. 2. <ul><li>Instructor’s note: About this slideshow </li></ul>This slideshow includes somewhat detailed slide notes. The notes convey the key ideas of each slide. This should allow the slideshow to be delivered well by any knowledgeable instructor. Note that several slides include built-in animations. The word [Click] in the notes is the cue to advance to the next animation. The slideshow is somewhat complex. In order to deliver it well, the instructor must be familiar with the sequence of animations and slides. Adequate preparation is important. Like every slideshow, this one is best delivered in the instructor’s own voice, not by reading the notes. The notes should be viewed as a guide, NOT a script . Any questions about this slideshow can be directed to Eli Sagor at [email_address] .
  3. 3. <ul><li>Workshop objectives </li></ul>Terminology and concepts Design two TSI treatments Tradeoffs How your company can profitably do more TSI Talking with landowners about TSI
  4. 4. <ul><li>What to expect today </li></ul>Overview – now Break Outside: site visits develop TSI plan discuss Lunch Outside: crop tree mgmt. Inside: review morning economics & operations Adjourn at 4pm
  5. 5. <ul><li>Housekeeping </li></ul>Break times Lunch Restroom locations Please turn cell phones off, or at least set to vibrate. Feel free to stand, move around, ask questions, etc
  6. 6. What is TSI?
  7. 10. David P. Shorthouse, University of Alberta, www.forestryimages.org
  8. 13. <ul><li>Timber stand improvement </li></ul>Any treatment designed to improve the FUTURE health, vigor, and value of a stand Primary goal is to improve the future condition and value of the stand.
  9. 14. Remove all vegetation Remove few dispersed trees Spectrum of harvest intensity Remove groups of trees Remove trees evenly through stand TSI Single tree selection Clearcutting Group selection Shelterwood (also thinning)
  10. 15. <ul><li>TSI vs. Thinning </li></ul>Textbooks: TSI = precommercial Thinning = commercial Today: TSI = precommercial AND some commercial Primary goal is to improve the future condition and value of the stand.
  11. 16. <ul><li>Key ideas </li></ul>MINIMIZE residual stand damage
  12. 17. <ul><li>Key ideas </li></ul>Balancing costs and benefits
  13. 18. <ul><li>Key ideas </li></ul>Plan for repeated entries
  14. 19. <ul><li>Key ideas </li></ul>Risk of windthrow from heavy thinning
  15. 20. <ul><li>Key ideas </li></ul><ul><li>Developing a specialization </li></ul><ul><ul><li>Match your equipment & markets to TSI type </li></ul></ul>

  17. 22. Examples: Four different kinds of TSI
  18. 23. Maps of public ownership Crop tree release Identify the BEST trees in the stand Remove competing trees Focus on CROWN competition USFS image
  19. 24. Kraft Crown Classification <ul><li>DOMINANT – trees with crowns extending above the main canopy—receiving direct sunlight from above and partly from the sides </li></ul><ul><li>CODOMINANT – trees with crowns forming the general level of the crown cover—receiving direct sunlight from above but little from the sides </li></ul>
  20. 25. Kraft Crown Classification <ul><li>INTERMEDIATE – shorter trees in the main canopy—receiving direct sunlight from above but not from the sides </li></ul><ul><li>SUPPRESSED –crowns entirely below the main canopy—receiving no direct light from above or from the sides </li></ul>
  21. 26. Only dominant or codominant trees should be crop trees.
  22. 27. USFS image
  23. 28. Maps of public ownership Row thinning Thin overstocked plantations Simple, efficient Focus growing space
  24. 29. Maps of public ownership Species thinning Remove undesirable species Leave desirable species
  25. 31. Maps of public ownership Cull tree removal Deformed, defective, undesirable trees Usually precommercial Girdle, herbicide, knock down
