Our approach is made possible through access to confidential U.S. Census data identifying property values surrounding all refuges with high geographic resolution. Results from hedonic property value models suggest that the amenity values of refuges located near urbanized areas are capitalized into the value of homes in very close proximity, averaging $11 million per refuge. These capitalized values add directly to the local tax base and are considerable complements to the annual economic value created by the refuge system.}, journal={ECOLOGICAL ECONOMICS}, author={Liu, Xiangping and Taylor, Laura O. and Hamilton, Timothy L. and Grigelis, Peter E.}, year={2013}, month={Oct}, pages={37–43} }
