Has anyone seen a good method to do damage appraisals, or to just set the value of a shelterbelt for land appraisal purposes? I have used the CTLA approach and also one developed by Dr. John Reeves and Edwin Franks at Western Illinois University for establishing an ecological value. This was described in Journal of Arboriculture, Oct 1988 page 255. Both have held up successfully on several occassions, but I feel they are better suited to individual trees or small groups than 10 mile shelterbelts.
Thanks for the help.

In the 1986 Manual for Plant Appraisers CTLA refrenced, but did not expand on, Helwig et al. The publication is undated but appears to be circa 1982. Full citations are:

Helwig, Larry, Norman W. Baer and Sheridan Dronen, n.d. The Investment Replacement Way to Find the Value of a Shelterbelt/Windbreak. South Dakota State University/Cooperative Extension. EC-740. This is the full paper.

Helwig, Larry, Norman W. Baer and Sheridan Dronen, n.d. How to Figure the Value of Your Shelterbelt. South Dakota State University/ Cooporative Extension. FS 801. This is a short flier.

Both are still available from SDSU publications, unfortuneately, I can't find that #. Current head of Extension Horticulture, Forestry, Landscape and Parks is Pete Schaeffer 605-688-5136 Fax 4713.

I have not been able to learn if the method was widely accepted in SD or elsewhere. I have looked at the methodology but have not really analyzed it yet. My interest is in the use of compounding. Please keep me posted on what you learn.

I have not used shelterbelt, but Category VII in the Field Form Report for Cost of Cure addresses the method.

Lew, I understood the inquiry to be about shelterbelts/windbreaks, the bands of trees planted typically in the plains to break the wind, prevent soil erosion etc. Category VII of 1995 CofC Guide employs "shelterwood" method of regeneration. I think the term comes from forestry. Maybe one of our forester friends can confirm.

Well, how can I resist the tempting hook re forester input from Scott. Shelterwood method - removal of the old stand in a series of cuttings, which extend over a relatively short portion of the rotation, by means of which the establishment of essentially even aged reproduction under the partial shelter of seed trees is encouraged. From: Smith, D.M. 1986. The Practice of Silviculture. 8th Ed. New York: Wiley. p.330. Shelterwood is one silvicultural method of producing a new stand originating from seed.

Hope that clarifies things!
