“…Gallinara (or Gallinaria) Island lies in the western Ligurian Sea, north‐western Mediterranean (Figure a), about 1.5 km from the mainland (Rovere et al, ). The nearshore hydrodynamics of the island are mainly controlled by waves coming from the south‐east and the south, with both directions having fetches of about 200 km and significant wave heights of about 2 m (Vacchi, Montefalcone, Bianchi, Morri, & Ferrari, ).…”

1. Marine Protected Areas (MPAs) are a major tool to conserve marine ecosystems but are also strongly attractive to tourists, the increased numbers of which can cause environmental issues if not properly managed.2. Proposing an MPA and then failing to establish it risks advertising the beauty of a marine area without managing the unavoidable increase in tourism. This is what happened at Gallinara Island (Ligurian Sea, north-western Mediterranean), where an MPA was proposed in 1990 but has not yet been established. 3. Benthic data collected soon after the proposal (1990-92) have been compared with similar information obtained in subsequent periods (2009 and 2016): change has been assessed both visually and statistically, using multivariate and univariate techniques. 4. The Gallinara sea floor supported five epibenthic communities in 1991, four of which corresponded to European Nature Information System (EUNIS) habitats; the fifth epibenthic community, characterized by the erect sponge Axinella polypoides, should be included in the next revision of EUNIS. 5. In the 25 years since the original MPA proposal, all epibenthic communities have exhibited a reduction in their three-dimensional structure and biotic homogenization, and severe decreases in species diversity, and the sea floor has been littered with derelict fishing gear and other waste from boats. 6. In absence of the MPA, proposals to develop a management plan for a marine Site of Community Importance (SCI) have been provided, to reduce sea-based human pressures. The dramatic alteration of Gallinara sea floor after 25 years of negligence and inaction is a sad warning for other unmanaged yet beautiful natural areas within urbanized regions of the world.

Here we review the multiple interactions between the endemic Mediterranean seagrass, Posidonia oceanica, and coastal geomorphologic processes as an outstanding example of biogeomorphology, taking into account recent advances in the field. Seagrass meadows are among the most important elements for the functioning of marine coastal ecosystems, and represent a major focus for research and conservation. Being considered a priority habitat, P. oceanica meadows are protected by several European Union directives and national laws. In this paper we examine: the role of sedimentary features in controlling the development of the meadows; the interplay between P. oceanica leaf litter (i.e. beached necromass) cast ashore and erosional-depositional processes on the beaches; the interactions between meadows and nearshore hydrodynamics, and; possible linkages between geomorphological features of the seafloor and the architecture of meadows. Finally, we provide perspectives for future research on P. oceanica and other Mediterranean seagrass meadows in a biogeomorphological context with specific reference to climate change.

“…When combined these data in a unique cartographic product, they can be easily used by decision-makers to assess territorial and marine features and locate vulnerable areas in need of conservation and protection. Recently, significant efforts were made to synthesize the outputs of research studies in a useful format for coastal managers (De Muro, Batzella, De Falco, & Porta, 2010;De Muro, Ibba, & Kalb, 2016;Rovere et al, 2015;Stojanovic & Ballinger, 2009). From this effort, several maps were realized by the scientific community to identify coastal hazards and/or coastal vulnerability (De Muro, Batzella, Kalb, & Pusceddu, 2008;De Muro, Pusceddu, & Kalb, 2010;Mendoza & Jimenez, 2008;Olita et al, 2012;Rovere et al, 2013).…”

2017) An integrated sea-land approach for mapping geomorphological and sedimentological features in an urban microtidal wave-dominated beach: a case study from S Sardinia, western Mediterranean, Journal of Maps, 13:2, 822-835, ABSTRACT An integrated cartographic approach has been used to summarize different data (geomorphological, sedimentological, hydrodynamic, ecological and anthropic) from an urban microtidal, wave-dominated beach and adjacent inner shelf in a comprehensive and easily readable mapping output. The study area is located in S Sardinia (Italy, Mediterranean Sea) and focuses on Poetto beach. All the data in this study were processed to produce a Main Map (1:6400 scale) showing the key characteristics of the entire area and three detailed secondary maps (1:56,000 and 1:59,000 scale) that include topographic and eco-graphic profiles, the distribution of sedimentary facies and the main anthropic impact. This map, providing detailed information on the beach dynamics, human impact and the marine ecological status of the Poetto urban beach, represents a useful new tool to facilitate environmental conservation and beach management.
