Despite a disease massively reducing the eelgrass around the 1930's, and the huge expansion of pleasure boating from the late 1950's, the eelgrass has greatly expanded.mooring
Hopefully the same applies at Porth Dinllaen.
Yes it has recovered but probably not to as great extent as at Studland.
The monitoring group are right that 10 percent of the sea grass meadow area is destroyed by mooring chain scouring.(average 10m radius scars can be seen around the regularly used moorings).
This is very much a function of the tidal range. It is going to be a long way to the pub in the dinghy this weekend with a 5 meter range!
They are still claiming without any proof that anchoring has the potential to damage and ask Boat owners to think responsibly about where they anchor.
There has been a significant loss of intertidal sea grass in the inner harbour by the pub but could this be as much down to high nitrate concentration(Pub Excrement?) as propeller and dragging/ beaching damage!
