Jersey has moved 21.7% of its territorial waters out of dredging and trawling
WHAT THE EVIDENCE SAYS
Effective September 1, the Government of Jersey expanded the share of territorial waters protected from dredging and trawling from 6.5% to 21.7%. The network is designed around sensitive shallow reefs and OSPAR-listed habitats including maerl beds, seagrass meadows and kelp, with government monitoring planned to track the effects of the new measures.
WHY IT MATTERS / OUR READ
The useful signal is that protected-area quality depends partly on which pressures are actually restricted, not only on how much area is mapped. Jersey's expansion links mapped sensitive habitats to specific mobile-gear exclusions. The next test is implementation: whether compliance, monitoring and fisheries adaptation translate those rules into measurable ecological outcomes.
CAVEATS / UNCERTAINTY
This is an official implementation announcement, not a before-after ecological outcome study. The 21.7% figure describes waters protected from dredging and trawling rather than a universal no-take designation, and some additional or sensitive areas remain phased or contested in the 2030 protection pathway.

New regulations expand the island's marine protected-area network from 6.5% to 21.7%, targeting maerl, seagrass, kelp and shallow reef habitats while leaving ecological outcomes to future monitoring.
