For this reason, on July 2013, Research & development

the structures consisting

of biodegradable coconut

biomats,filled with the remnants

of P. oceanica removed from the

shore, were prepared following

the methodology described

above. Some beaches were

partially freed by the deposits

of marine plants, returning to

full fruition during summer

(period of greatest tourist

visits).

The “mats”, stuffed with seagrass

collected from the beaches,

make them eligible to avoid

accessibility of tourists close to

unstable and rocky cliffs (Figure

13a) and to cover on rocky and

rough areas (Figure 13b). They

are also suitable as a substrate

for the restoration of the sea
