Payne, B.R. and S. Strom. 1975. The contribution of trees to the appraised value of unimproved residential land. Valuation, 22(2):36-45.
A 12 acre parcel of unimproved residential land in Amherst, Massachusetts was examined by professional appraisers. The value of seven simulated combinations of distribution and amount of tree cover was estimated. It was determined that arrangements with trees were valued higher than arrangements without trees. For a fixed percentage of tree cover, scattered arrangements of trees were valued higher than concentrated arrangements.
