CVUUS’ Ash Tree Future

We discussed options for our existing ash trees on the CVUUS campus and planted more trees for future canopy and shade.  See the outline from Paul Stone below. Contact Facilities Chair Bob House with any comments.

An Outline to Facilitate Tree Discussion

Bob has already framed the discussion with three questions

  1. What to do about ash trees and EAB
  2. Trees in wetland
  3. Shade trees on west side of sanctuary

Emerald Ash Borer

  1. Our decisions should be guided by aesthetics from inside and outside
  2. And by need for shade in summer heat
  3. And by how much CVUUS wants to spend
  4. Per experts Mike and Chris, injectable insecticide treatment every other year is very effective and for long term
  5. Cost $200 to $250 per tree per treatment every 2 years
  6. Removing dying ash will not improve the longevity of the treated trees
  7. Wetlands
  8. Trees suitable for wetlands: red maple, tamarack (larch), swamp white oak
  9. We have already planted 11 red maple, and 1 tamarack, 1 silver maple, and there is 1 sugar maple started by itself
  10. There is probably room for more trees
  11. Once these trees get established and some height we can determine if there are too many and remove some it desired
  12. Elm: there are many elm trees in various stages of health from thriving to completely dead.  Cut dead?  Or leave for nature to take its course?
  13. Shade trees, west side
  14. We have suggestion from Mike and Chris of honey locust; red maple, silver maple, Valley Forge elm; catalpa, service berry; Japanese lilac
  15. They suggested not using nut trees because of nuts on sidewalks being a danger
  16. I think both suggested a honey locust between side walk (at the level between the stairs) and the sanctuary
  17. Honey locus leafs out a bit latter in spring so would give sanctuary a bit more sun in cool May. And most importantly the leaves are small and can be easily raked under shrubs for mulch.
  18. Green Haven Nursery, Rt 7 North, has several large trees available.
  19. Skyline Honey locust
  20. Ivory Silk Tree Lilac a large blooming tree
  21. Autumn Blaze Maple, cross between silver and red maple, leaves turn red in fall.  Is faster growing that either parent
  22. Pricing for above is $700 includes guarantee. Now 25% off but no guarantee.
  23. White Satin Birch $300
  24. The above are all large trees about 12 to 15 ft tall in a big dirt ball. These are nursery stock, not dug up from a field,  so roots are all there.
  25. Cost to transplant: $300 for first tree and $200 per tree after that.   These have large root balls too big for us to handle.  Transplanting includes topsoil, tree saver (some sort of magical stuff for a healthy tree) and mulching.
  26. They also have potted trees that we would have to plant. $250 and up.
  27. Defining play area: this discussion is not a priority at this time and should be put off until more has been developed about specifics for a play area and its location.
  28. Horsford Nursery, Charlotte
    1. Thornless Honey Locust 15 gal   $279 – 20%  = $223
    2. Autumn Blaze, red x silver maple 10 gal, $199 – 20%  =  $160

     

    1. Gardeners Supply, Williston:
    2. Red Sunset, 15 gal,  $215 – 50%  Oct 9th  =  $108
    3. Red x silver cross,  15 gal,   same,  = $108
    4. Sycamore 15 gal  same,  =  $108

    Turns out after many questions that #4 above is not what I thought. These large trees were grown in a field and dug up this spring and stored in a burlap ball.  These trees are perhaps 15 years old so the had long roots which all got cut off in the digging up.   Our consultant Chirs cautioned against these trees as without their major roots supplying water and nutrients the trees do poorly.  Chris recommended the potted smaller trees that have spent their whole life in a pot and have an extensive root system intact.
