Re-establish the three-mile limit on bottom trawling and dredging all around Scotland's coasts

From 1889 bottom trawling and dredging were banned anywhere within 3 miles of shore. This protection was removed in 1984 leading to the progressive collapse of fisheries all around Scotland's coastline. Marine Protected Areas (MPA’s) supposedly cover 20% of coastal seas, but in reality under 5% are off-limits to scallop dredging and bottom-trawling.

The three-mile limit on bottom trawling and dredging should be re-established immediately.

Why the contribution is important

Seabed habitats are vital as fish spawning grounds and nurseries, and they are significant carbon stores rival to any on land. The top 10cm of Scotland’s seabed holds more carbon than all the peatlands, soils and trees Scotland combined. These habitats protect our coasts from storm surges and wave action, and can ameliorate the rising ocean acidification that is being caused by global warming. These carbon stores have no chance to recover as things stand.

    As the author has identified, the seafloor sediments are vital repositories for GHGs sequestered from the water and therefore from the atmosphere. Disturbance of such sediments is likely to result in the release of the stored gasses.

    If confirmed, this '10cm of seabed holds more carbon than soil, peat and forests' data means this action is highly important
