Cost benefit analysis of conservation efforts to preserve an endangered species: The Griffon Vulture (Gyps fulvus) in Israel

Abstract

The major goal of this study was to determine whether protective measures in the case of the Eurasian Griffon Vulture are in accordance with public priorities. To this end we used the Travel Cost (TCM) and Contingent Valuation Methods (CVM) to estimate its value. We also determined the break even point in the allocation of funds targeted to protection at the regional level and performed a cost-benefit analysis of conservation efforts on a national level in Israel. The value of the marginal vulture was found to be approximately 34,000 NIS at Gamla and 316,000 NIS at Hai-Bar Nature Reserves. The economic efficiency of feeding stations was examined from two aspects: At the regional level, the break-even point for a feeding station to be efficient was 0.24 and 2.20 vultures per year for the Hai-Bar and Gamla NRs respectively. At the national level, in most cases, the national project to save vultures, ‘Porsim Kanaf’ (‘Porsim Kanaf’ is the national birds of prey conservation project in Israel) passes a Cost-Benefit test based on the valuation results.
