Recreational boating in the Portofino Marine Protected Area (MPA), Italy: Characterization and analysis in the last decade (2006–2016) and some considerations on management. (May 2021) - Venturini, S.
Abstract: Recreational boating is a significant nature-based activity, which is especially popular in the Mediterranean region. This study analyses this activity in the last decade in the Portofino MPA, a popular recreational boating area in the Ligurian Region (northwest of the Italian peninsula) in order to evaluate the maximum turnout and to provide management considerations to better achieve conservation and environmental management of a MPA. Monitoring activities were carried out during the summer from 2006 to 2016 and allowed locating the most critical sectors of MPA in consideration of different factors and kinds of boats. From the results of this long-term monitoring, the first conducted in Italy, it is evident that only some anchoring sectors of the Portofino MPA may suffer impacts from recreational boating and that the boats have different spatial and temporal distribution depending on the different summer months, on the public holidays and on weather conditions which mainly affect the boats units < 10 m (73% of the monitored boats). Due to direct impact of the anchorage on the seafloor, which hosts peculiar natural habitats, and the fairly constant presence of the recreational boaters over the years, different solutions for better protect the seabed without excessively prejudicing the enjoyment of recreational boating are discussed. Since the San Fruttuoso seagrass-friendly mooring area is one of the most visited sectors in the MPA, an increase in the number of seagrass-friendly moorings combined with a higher delimitation of the areas with special habitats may represent an optimal strategy.
