We went to a lecture by the marine officer of the Essex Wildlife Trust last week, about "Living Seas" which is the grouping that bid for, and was granted, the MCZ covering the Blackwater and Crouch/Roach. She is called Sarah Allison, and is worth talking to if you still have any concerns about how the MCZ would interfere with boating activities.
Her main concern is the native oyster and oyster beds. She has been working with the oystermen in the Blackwater to survey the oyster beds, and it was that very careful research which was instrumental in getting approval for the MCZ. She found that while most of the native oyster beds are reasonably healthy, some, notably in the approach to the Ray Sand channel, only have mature oysters with no young ones at all. They have no idea why, but have got approval for a ban on dredging for native oysters for a few years in most of the Blackwater (I think). They can still dredge for the invasive species, the Pacific oyster, which conveniently favours intertidal areas, while the native likes depths of 1-4m.
Someone asked about boating - she said that the oysters/oysterbeds seemed to thrive on being periodically dredged, so the odd anchor wasn't going to make any difference, and that was the only impact that she could think of, so didn't think boating was any problem. She also said that the oyster beds in the Crouch were largely seeded and managed privately, so were not really her concern, but I guess the same lack of problem with boating also applies.
She said that we do have eelgrass in this area - the best protected eelgrass in the country, because it is largely on Foulness sands and if you get anywhere near it, the army appear and point guns at you!
There are also sea horses, but since the only ones found were dead ones in the filter into Tilbury power station, they were of no concern yet, till more research is done to find out where they have come from (possibly the Foulness gunnery ranges).
We could invite her to a EC dinner, like we did when the Balanced Sea lot were consulting. Honestly, though, I cannot see that we need worry about this MCZ.
