Use environmentally-sensitive material on intertidal artificial structures
A replicated, randomized, controlled study in 2008–2009 on two intertidal rocky reefs on open coastlines in the Celtic Sea and the English Channel, UK (Coombes et al. 2011) found that limestone settlement plates supported lower microalgal abundance than concrete plates, while abundance on granite plates was higher than or similar to concrete depending on the type of microalgae. After eight months, round microalgal abundance was lower on limestone plates (5% cover) than concrete (61%), and higher than both on granite plates (82%). Filamentous microalgae was less abundant on limestone (13%) than granite (33%) and concrete (30%), which were similar. Settlement plates (100 × 100 mm) were made from limestone, granite and concrete. Two of each were randomly arranged horizontally in each of two patches at midshore on each of two rocky reefs in May 2008. Microalgal cover on plates was measured using a scanning electron microscope after eight months.
