Marine Conservation Society: Lancashire area group

This will be an informal event looking for and recording some of the creatures that can be found on the shore at Roa Island. Low tide is at 7:30pm and will be particularly low – at 0.5 metres it should expose more of the shore than most tides which means that many creatures that are often only seen by divers may be found. There are also some creatures that divers don’t normally see that are easier to find when the tide has gone out.

Suitable for all ages; children must be supervised by a responsible adult. Meet at the top of the Jetty next to the Lifeboat Station @6:15pm – map reference SD 232648.

What to bring?

Must haves -

• Wellies, sandals or other shoes that you don’t mind getting wet and probably a little muddy;
• The same applies to your clothes; also bring some warmer clothes – the shore is exposed so can feel chillier than places on shore.

Optional extras -

• A towel and a change of clothes just in case may be a good idea;
• Shallow trays or a bucket to put creatures in to study (but be sure to put them back carefully exactly where you find them!);
• A net;
• A camera – but be aware that sea water and cameras do not mix well, if you bring a camera and have a waterproof housing then please use it and in any case take extreme care on the shore not to drop (or even put) your camera into water;
• A torch – preferrably a waterproof one, or another good option would be a head torch (sunset is @8:10pm, dusk 8:45pm).

Anything that you bring or wear will be at your own risk.

If anyone wants to car share please let me know and I will try to arrange to meet at the westbound layby on the A65 about half a mile east of junction 36 of the M6 – map ref SD 541821. But note that timing will be a little tight for some of us to get away from work and get to the meeting point in time and that I will NOT do this unless it is requested and I can arrange to leave in time to get to Roa Island.

The hardest coral on the reef may well be a softie, as much of the rocky structure of these reefs is found to derive from the sclerites from soft corals! This debate over how much support environmental agencies will grow as our economic worries deepen, how high up the scale do you put the environment? Essential for our continued existence on the planet, or jobs/hospitals now (environment later – maybe)? This week DSN reports on the debate in the US in our conservation leader. Our pollution section, however, points out that one of the most damaging aquatic pollutants – nitrogen from fertilisers – can be reduced while saving money and increasing yields…

A cracker of crazy stuff from the ocean this issue: Our contribution to shark week this year might be a shark with a hump – or the camel with very sharp teeth… Plus buzzing lobsters, binary snails and when to fix your beach defenses. Perhaps the best news this issue is the partial recovery of the Grand Banks fishing area. White fish stocks had been reduced close to extinction, and this set up feedback loops that resulted in smaller fish and squid taking over, as they ate what few young fish that were born. After over 20 years of ban, however, there are signs that the cod are coming back… Lessons? – Stop fishing before you hit stock bottom (unless you can survive 30 years without work that is)!

Over the last few years we have built up a species list for the Hotel beach and wall at Lochaline. Most of the work has been done by Ron Crosby, with occasional contributions from other embers of the group. This year, however, we are glad to welcome contributions from Ron Ates and Godfried van Moorsel, both based in the Netherlands. Their additions (and corrections) take our list up to 122 named species – not bad at all for 100m stretch of coastline! Mind you the coastline is very conducive to diving, with easy access over a gently sloping beach, leading to a near vertical drop down to 80+m. This makes a wide range of habitats readily accessible to the diver – and reminds us about how much there is in the seas around our coasts.

Below is a quick breakdown table of the life recorded, for a full species list see our survey page:

Group	No. Species
Algae	15
Sponges	8
Cnidarians	20
Worms	13
