Abstract
Formulas developed to determine the monetary value of landscape trees require a species rating value. Polling Extension professionals, researchers, and arborists is a common procedure to derive species rating value. Due to differences in professional training and background, and the variability of landscapes in any given area, professional agreement on the rating of a species is difficult to reach but is necessary to be useful. The Delphi method and W criterion were used to determine the strength of concordance among extension professionals. We hope that other Extension professionals can use this method in developing species rating in their respective areas.
