Aesthetic indicators of landscapes, expressed as individual scenic beauty estimates, may be used as proxies of individuals' specific aesthetic values, and improve the properties of welfare estimates produced by contingent valuation models. This work presents results from an interdisciplinary study where forest scenic beauty indicators are utilized in an economic valuation study approximating welfare estimates from increased forest fire protection. The omission of scenic beauty indicators from the economic valuation of environmental resources produces biased and overestimated welfare measures. Combining economic and environmental indicators significantly improves the explanatory power of economic valuation models and of the produced welfare measures. Such a combination, however, is only possible when carded out by interdisciplinary research teams. The results of such research are significant to environmental and natural resource policy makers and planners.
