Description
Marine Protected Areas' (MPAs) and Artificial Reef's (ARs) management requires complex assessment and monitoring programmes, dealing with different sources of variability. We studied and developed experimental designs and analysis methods suited for the establishment of a monitoring of MPAs and ARs. This methodology is developed from existing data sets in the Northwestern Mediterranean. We build multi-criteria indicators allowing a statistically testable diagnosis of the impact of MPAs and ARs on reef fish assemblages. Using ecological performance indicators permits to monitor and to give an image of the assessed system to managers. It was possible to show the global response of the fish assemblages to the protection by a MPA. This response was evidenced by increases in abundance, species richness or diversity, gradually through space, time and among various taxonomic groups or fish individual sizes. Large fishes reacted faster to protection and shallow habitats were more sensitive to the existence of a MPA. Our results can be useful for the implementation of new MPAs or for the immersions of ARs and for the development of their management plans.
