Presentation Transcript

  1. Shelterwood

  2. Shelterwood • Regeneration cut • Modify environment of regen • Provide seed source

  3. Even-age regeneration • Length of regeneration time varies by circumstance

  4. Process • Create available growing space for regen • Removal of part of the overstory • Remove remaining overstory before growth of regen is overly inhibited

  5. Stages • Prep cut(s) • Final removal

  6. Difference from Thinning • Purpose is regeneration • Main objective is not future growth of residual stand • Can be secondary objective

  7. Usually for natural regeneration • Can be supplemented with planting • Species • More uniform stocking

  8. Classic 3-cut Shelterwood

  9. Money Upfront

  10. Irregular shelterwood

  11. Strip shelterwood

  12. One cut shelterwood

  13. Framework • Age structure • Species composition • Disturbance regime

  14. Yield • Growth of regen • Growth of remaining overstory

  15. Possibility of carrying some trees into next rotation • Not part of “shelterwood” per se • A variation worth considering • Turns a single cohort stand into a two cohort stand

  16. Veg Management • Difficult • Major problem if competition is more shade tolerant than the desired species

  17. Logging equipment • Almost anything can be used • Cable on steep slopes can be difficult

  18. Cost • Can be lowest cost • Two or more harvests • Increased growth of overstory • Regen can be cheap

  19. Aesthetically desirable • Continuous green cover
