In yesterday’s JEP, Jack Maguire had a short article on the idea of furrowing the beach to help prevent sea lettuce accumulation next season. There were some worrying mistakes in it, so here is the article and our correction:
The JEP article ‘SOS propose accelerating flow of outgoing sea water’ [18 august 2016] is incorrect about the width of the proposed channels. They will have given readers the impression the channels are going to be very wide and all over St Aubin’s Bay! SOS Jersey would like to reassure everyone that the proposed channels are not going to be 400 metres wide, but 400 metres LONG and ONE furrow wide.
To clarify, these furrows would be low and temporary and dug at specific angles to the tidal flow. Sea lettuce will wash up and down with each tide, but these channels should prevent it from gaining a hold in the intertidal areas and other specific areas and, as a result, stop its accumulation at the top of the beach.
The furrowing will be done early in the season and repeated if necessary; this approach is meant to be a short term, partial solution to the sea lettuce problem until the Jersey native oysters programme starts to show results. We are mindful of tidal flows and of the local flora and fauna, and furrowing plans reflect these.
We would also like to clarify that SOSJ have acted as facilitators in the proposed Jersey native oyster project and haven’t the resources to carry out further surveys. We will issue no proposals: that is for the relevant States department to do. We will monitor and help when possible, but Infrastructure are now in a position to continue the sea lettuce project in collaboration with Tony Legg of Jersey Sea Farms.
