Valuation of Trees in urban parks by CAVAT (Capital Asset Value for Amenity Trees) Method

The valuation methods can also assist in differentiating lower from higher value trees. CAVAT (Capital Asset Value for Amenity Trees) provides a method for managing trees as public assets rather than liabilities. The Quick method potentially involves three steps, and key variables Basic value, Community Tree Index (CTI) value and Functional Value. CAVAT works by calculating a unit value for each square centimeter of tree stem, by extrapolation from the average cost of a range of newly planted trees. The value was calculated for the twelve tree species growing in urban parks of Isfahan. Results show that Fraxinus excelsior, Populus nigra, Cupressus arizonica have the maximum value Quercus alba, Acer saccharum, Ulmus carpinifolia have moderate value and Ailanthus altissima, Robinia pseudoacacia and Salix alba have minimum value in the urban parks of Isfahan.
