sealord > This is the mid-shore area of the southern end of Belle Greve Bay near the Salerie quay looking out towards the Quaine pole in the distance which is reachable by foot during an extremely low tide. I found this Guernsey Safeway plastic carrier bag lying on the beach and took an image of it before picking it up. Guernsey retail food shoppers used about 10 million plastic carrier bags per year before a £0.05 charge was introduced in 2008. Stopping the free distribution of plastic carrier bags at Guernsey retail food shops has significantly reduced the number being distributed. However a few plastic carrier bags still end up in the environment. Because of their light weight, some plastic carrier bags are blown onto the shore where they may be carried out to sea to be ingested by cetaceans, marine birds or turtles. See http://pagesperso-orange.fr/gecc/publications/pdf/PosterSeattle2002.pdf Those that don't get ingested can degrade to invisible microscopic particles which then begin their journey through the food chain back to humans. Disposable plastic carrier bags represent such a wasteful use of oil. They provide a short term convenience and a long-term environmental hazard. Please bring a shopping bag with you when you shop. There are plenty of ways of remembering to bring a shopping bag with you. I have one attached to my belt loop so I never forget it.

sealord > This orange sponge, Hymeniacidon perleve, is common and conspicuous half way down the shore in Belle Greve Bay. It grows on rock surfaces which are exposed at low tide to direct sunlight and wind. The sponge grows in patches about 15 cm across. This image was taken on the 17 April 2007.

sealord > During the large equinoctial spring tide of March 20, 2007 ormer (abalone, Haliotis tuberculata) gatherers search the Guernsey shore for the delectable mollusc. The brown kelps in the foreground are Laminaria ochroleuca. Low water was at about 0.2 metres above chart datum at about 1400. In the distance buildings line the Belle Greve Bay waterfront.

sealord > This image shows the lower shore of Belle Greve Bay after ormer (abalone) gatherers have turned over boulders looking for the elusive mollusc. All the pale boulders have been overturned and left upended. Many marine biologists visiting Guernsey from the UK have commented on the damage done to the shore by shore gatherers not returning boulders back to their original position after turning them over to look for the ormer. The tops of the boulders are covered by algae and particularly the pink crustose coralline algae, which issues pheromones which attract settling ormer, Haliotis tuberculata, larvae. The base of boulders are covered in many sessile invertebrate species including spirorbid tubeworms, bryozoan colonies, and ascidian colonies. When boulders and cobbles are turned over and not returned to their original position the algae that were growing on the top die and the invertebrate colonies from the base of the rock die too. The boulder quickly becomes colonised by opportunistic green algae and gradually over time and through succession a more complex community of species adheres to the boulders. If the boulders are turned over too often and the shore suffers too much disturbance macroscopic species diversity deceases. There is a hypothesis that intermediate disturbance allows for the greatest species diversity. File No. BG 210307 30-890 Copyright©RLLord fishinfo@guernsey.net Boulders turned over BG 210307 30-890
sealord > This shallow pool in the foreground with its scattered coralline algae covered boulders and cobbles is where I found the first Guernsey record for the nudibranch, Janolus hyalinus, on the 17 February 2007.
