Overall , work has management implications - the reef is an important component of a SAC this M. modiolus reef type is morphologically and acoustically distinct can be mapped and monitored accurately using acoustics Side-scan sonar was the most discriminating method used Similarity over several years indicates that a spatially targeted, long-term programme of acoustic monitoring is achievable. However, to detect anthropogenic impact and the possible consequences of it: a swathe system ability to analytically differentiate acoustic backscatter would probably be most appropriate. because degradation to clumps requires backscatter analysis when the relief is nolonger visible Degradation of Modiolus in Strangford Lough has possibly occurred as a result of trawling causing progressive fragmentation (Roberts et al 2004)
