Dupré, E., Pedrotti, L., & Arduino, S. Alpine Ibex Conservation Strategy - The Alpine ibex in the Italian Alps: status, potential distribution and management options for conservation and sustainable development. 1-126. 2001. WWF International. Keywords: 8IT/Alps/Capra ibex/conservation/development/distribution/growth rate/ibex/Large Herbivore Initiative/LHI/Malme/management/population size/reintroduction/ strategy/susceptibility/translocation Abstract: This study presents the first comprehensive overview of the status of Alpine ibex in the Italian Alps, based on an extensive data collection used according to a standardized methodology. For the first time, a thorough synthesis of information on the 69 Italian ibex colonies is available, covering traditional themes such as distribution, population size and growth rate, but also more specific issues such as the year and cause of origin, number of translocated ibexes, and type of management. Then, a comparison is made between current and potential ibex status and distribution, and implications for the conservation and management of the species are presented. The potential situation (distribution, size, density) is estimated by applying two models that assess the quality of ibex habitat and predict ibex potential distribution at the local scale for the entire Italian Alps. The two models had already been conceptually developed from data on different ibex populations living in the Italian Alps (one for the siliceous substratum and one for the calcareous-limestone-dolomite substratum), but, for the purpose of this study, they were redesigned to reflect the coarser scale of the data available for the whole Italian Alps. Their application to the study area according to the underlying lithological substratum revealed the gap between current and potential status and contributed to identifying conservation and management issues and developing recommendations for future reintroduction programs.
