Proposing a network of marine protected areas in the central Ionian archipelagos and the Korinthiakos gulf

Abstract

We identified priority areas for conservation to complement the existing marine protected areas (MPAs) in the Central Ionian Archipelagos and the Korinthiakos Gulf, Eastern Mediterranean, based on the principles of systematic conservation planning. This transparent method for the design of MPA networks is considered more efficient and successful in representing the biodiversity of a region. In order to apply systematic conservation planning we used the computational tool Marxan. Our objective was to provide adequate protection for the biodiversity of the study area while minimizing the impact on the socioeconomically important human activities in the area. We used 17 conservation features (species and habitats) as well as surrogates for three fishing sectors and tourism to estimate the socioeconomic cost, as inputs in our analyses. After classifying our features into two categories (high and low priority), we created three scenarios with different targets for our conservation features: low (60% and 20%), medium (70% and 40%) and high (80% and 60%). The low target scenario demanded the protection of 24% of the study area, the medium 34% and the high 45%. The proposed network of MPAs should be subjected to zoning and adaptive management, supported by solid monitoring and evaluation of previous management decisions.JRC.H.1-Water Resource
