  8. 8. 8 Family Property • Washington County, Minnesota • 12. 5 acres • Rolling hills • Native habitat: oak savanna • Nearby: old farm with buckthorn hedge
  9. 9. 9 Family Property (con.) • 1960s red and Scots pines planted • Family began buckthorn control – late 1990s • Forestry Management Plan – early 2000s

  17. 17. 17 Three Phases of Tall Stump Treatment Method • Preparation • Cutting • Treatment
  18. 18. 18 First Phase - Preparation Not out-of-the-ordinary: • Determine Objectives – Convert to oak savanna and woodlands – Restore slowly • Cruise Property – Mark desirable species – Identify worst buckthorn trees
  19. 19. 19 Worst Buckthorn • Berries are the key • One mature female – 400 to 1800 fruits – 1200 to 5400 seeds – Over 5 year period = 6,000 to 27,000 seeds • Ignore small trees
  20. 20. 20 Traditional – 2nd Phase • Pulling • Girdling • Foliar • Basal Bark • Cut Stump • Frill (“cut and squirt”) Tall stump method is combination of these two with some twists.
  21. 21. 21 The 2nd phase of the tall stump Method only involves stump cutting
  22. 22. 22 2nd Phase of Tall Stump: Cutting • Tools: loppers and folding hand saw • Cut trunk high • Cut big branches • Leave tall stumps
  23. 23. 23
  24. 24. 24 Tall Stumps Can be Quite Tall!
  25. 25. 25 After cutting you can wait for months if you wish before 3rd Phase.
  26. 26. 26 3rd Phase: Treatment • Tools: – Scraper (or hatchet, machete, etc.) – Herbicide applicator • Use frill method at tree base
  27. 27. 27
  28. 28. 28
  29. 29. 29
  30. 30. 30 3rd Phase: Treatment (con.) • Winter – ideal time. • Glyphosate (20% to 30% concentration). • Control should be effective
  31. 31. 31 Advantages of Tall Stump Treatment Method
  32. 32. 32 First Advantage: Efficiency • Fewer Tools for each phase: – Cutting phase – hand saw and loppers – Treatment phase – scraper and applicator • One tool in each hand • More space to work in treatment phase
  33. 33. 33
  34. 34. 34 Second Advantage: Split Work Up • Cutting phase and treatment phase are distinct – Optimum cutting – late spring early summer – Optimum treatment – winter • Can be separated by months
  35. 35. 35 Third Advantage: Identification of Tall Stumps • Easy to identify tall stumps for treatment – in snow or leaves after stump cutting • Easy to identify dead tall stumps – avoid tripping on them
  36. 36. 36
  37. 37. 37 Fourth Advantage: Tree Tops Removed • Reduces fire hazard • Makes walking easy
  38. 38. 38 Fifth Advantage: Better Outcomes • Frill exposes more cambium for treatment than traditional cut stump = better outcomes • Frill at base of tree is nearer roots and improves results
  39. 39. 39
  40. 40. 40 Sixth Advantage: Correctable Failed Treatments can be easily corrected
  41. 41. 41 Sixth Advantage: Correctable (con.) • If you forget to treat a tall stump. . . • Growth will occur at the top
  42. 42. 42 Sixth Advantage: Correctable (con.) • It’s not difficult to: • Cut top off and • Treat again
  43. 43. 43 Sixth Advantage: Correctable (con.) • But at least you don’t have a bush to deal with:
  44. 44. 44 Seventh Advantage: Better for Environment • No soil disturbance • Better target surface means less herbicide • Uses glyphosate – relatively benign
  45. 45. 45 Eighth Advantage: One Person One person can easily undertake • Fewer tools • Separated into phases • Great exercise • Quiet and great way to enjoy being in the woods All of this helps to. . . .
  46. 46. 46 Reduce Invasives Anxiety
