    "description": "Sabellaria spinosa presence record from study into the effects of marine gravel extraction on the macrobenthos: early post-dredging recolonization. A small area of sea bed off the English east coast was experimentally dredged by a commercial suction-trailer dredger. Some 50 000 t of mixed aggregate were removed, representing 70% of the sea bed area down to an average depth of 0.3m. Results from benthic surveys undertaken at the experimental site and nearby reference site indicate that significant reductions had occured in the variety, abundance and biomass of benthic organisms as a consequence of dredging.",
