Exploring Shoreham Beach Local Nature Reserve

I worked with a group of students on Shoreham Beach Local Nature Reserve, one of my Pupil Enrichment Programme session, for West Sussex County Council. The course started in a local school near the nature reserve allowing some classroom preparation.

We started by looking at how varied the Sussex Coastline is in regard to habitat types which include pebble beaches, sandy beaches, sand dunes, chalk cliff and wave cut platform and various coastal developments.

We looked at how the sea can create beaches (such as shingle spits like Shoreham) or erode coastline such as chalk cliffs. The pupils were provided two different scenarios to complete and predict what happens next, a shingle coast and a chalk cliff coast. After this we discussed how Shoreham Beach was formed by longshore drift and the flow of the River Adur.

We looked at how Shoreham Beach has played a major part in local maritime history – such as the port and ship building.

The students were given a selection of pebbles from the beach to identify and comment on their origins.

These included a large flint pebble, piece of flint from the South Downs, chalk, sea coal, a brown flint, a long shaped flint and quartzite.

Much of the day was spent investigating the local nature reserve. The students were divided into two groups and took turns in various activities.

This included a beach transect survey from the top of the beach to the shingle crest identifying and recording the numbers of each species present.

This helps to build up a profile of the plant communities.

Another activity involved students looking for adaptation features that different shingle plants use to survive in this harsh habitat, from a list provided.

Once they had found a plant with the adaptation, they then used identification guides to identify the actual plant.

Two separate animal surveys took place, one to record generally the birds, lizards and invertebrates that visit the shingle plant habitat.

The second focusing on recording three types of bee, to also discover which plant species they favour.

We finished the day back at the school with a recap of what we had done, what they had discovered and a general round up and a chance for final questions.

Tide Pool Event Shoreham Beach

This is the third year I have run this popular tide pool ramble, with an estimated 60 adults and children. The beach is just inside Shoreham Harbour, adjacent to the Old Fort and the Shoreham Beach Local Nature Reserve. The event is part of the Friends of Shoreham Beach annual events programme.

It is a very safe beach for family events providing the opportunity to explore both a sand/silt habitat and a rocky habitat all in one place. The beach is also visited by a variety of sea and wading birds such as terns, cormorants, gulls, turnstones, dunlins, oystercatchers and little egret.

As usual we started off with an introduction about inter-tidal zone wildlife and this year I did a quick demonstration on the causes of tides inlcusing spring and neap tides using a cardboard cut out of the sun, earth and a yellow ball for the moon. This was done with the help of three child volunteers.

Everyone then spread out across the pools and explored the beach as the tide receded.

We helped by pointing out various seashore creatures and identifying the wildlife finds and generally providing facts and information about the animals that were discovered.

A juvenile plaice. Juvenile fish often live in the river estuary where they are safer from predators.
A compass jellyfish stranded on the beach. I carefully moved it to a rockpool to see if it was still alive, but sadly we discovered it too late. A volunteer stayed by the jellyfish to make sure no one touched it (as they can still sting when dead) and also to tell people about the jellyfish.
A dead eel was also discovered on the beach. It appeared to be partly eaten but the skin was still quite shiny in places and the fish did not smell so it must have died very recently.

We set up a small tank and containers at the top of the beach to temporarily house some of the discoveries so we could talk about them at the end of the event.

We identified and kept a record of the marine life discovered during the event.

These included lugworm, sand mason worm, shore crabs, common prawns, sand hoppers, edible periwinkle, chitons, barnacles, dogwhelk, bass fry as well as animals mentioned above.

After a picnic lunch, the Friends of Shoreham Beach organised a beach art activity. Children created sea creatures on the sand using pebbles, shells, sea weed and other debris washed up.

The children produced some great sea creature art and prizes were awarded for some of the best.

Brighton Science Festival 2009

I attended the Brighton Science Festival again this year with a joint display with the Friends of Shoreham Beach Nature Reserve (FoSB). The Shoreham Beach Display included information about the Reserve and FoSB activities, events and achievements. A large part of the display was taken up by a marine litter display "Turning the Tide on marine Litter" and a display of marine litter including the time it takes for each item to biodegrade. (See below)

We shared the room with another display about creating art from marine litter.

My display focused on sea mammals again this year, particularly dolphins and seals, both of which have been recorded at Shoreham.

As well as UK and Sussex Cetaceans (Whales, Dolphins and Porpoise) the display included information about local seal sightings and a satellite tagging programme on Solent and South East Channel Seals.

I will be involved in this project as Sussex County Recorder for Sea Mammals and to develop an education pack to accompany the project. I hope to be able to provide updates on this project in future entries.

A major focal point for my display was the life sized inflatable bottlenose dolphin. This year I also ran three demonstrations in the demonstration hall, the scenario for the demonstration was a re-enactment of a dolphin rescue with audience participation.

Dolphins may be stranded for many reasons so I chose a different scenario for each demonstration, one of them being entangled in marine litter debris, which again linked to the FoSB display. About 100,000 marine mammals, seabirds and turtles are killed by debris each year.

Moving the dolphin from the display room to the demonstration room was a difficult operation, avoiding people and navigating along various narrow corridors.

The demonstration started with a introduction to dolphin adaptation and anatomy, as this is knowledge the audience would need to know to affect a rescue.

The demonstration followed the series of things one should do to help give first aid e.g. check it is breathing (how often!), keep it wet (dolphins can very quickly die of heat exhaustion), dig holes around the flippers if possible to alleviate the damage that gravity causes (dolphins can’t swim if they damage their flippers) and so on (see above)

The re-enactment also demonstrated how a dolphins adaptations to aquatic life work against them if they become stranded on land.

Being a demonstration involving children, each scenario has a happy ending. The dolphin was helped back into the sea and walked around until it was able to swim unaided. But in reality, even after much effort, a happy ending is not guaranteed.

Wading birds, pebbles and hagstones

Took a trip to the Shoreham beach yesterday with my daughter to collect some pebbles for a coastal display that I will be running for the Brighton Science Festival on Saturday 23rd February. I started at the footbridge, crossing the River Adur. The tide was on its way out and there was a lot of bird activity. Apart from the various gulls, a large flock of grey plover were feeding on a small island of estuary and mussels.

On the mud flats on the far side of the river there were several redshank feeding. Redshark have relatively long legs and stride over the soft mud probbing every now and then with their long beaks. The display will be mainly about the Shoreham Beach Local Nature Reserve and will also be run by the Friends of Shoreham Beach (FoSB).

This is an exciting new nature reserve established in June 2006 and which I have been very pleased to have the opportunity to be involved with both as a member of the management group and as a honary member of FoSB.The beach is comprised of a large shingle spit, formed as the result of several centuries of wave action and westerly deposition of the shingle - Longshore Drift. Above the tide line, where the shingle is stable, is vegetated shingle, a rare habitat for the UK and worldwide. The shingle plants die back during the winter ready for a dramatic transformation in the spring when the plants will burst back into life.

Anyway, more about the shingle. People often this that the shingle is boring but it is infact very interesting. 98% of the pebbles are flint washed into the English Channel at the end of the last ice age or have been left behind as the chalk coast eroded in more recent times.

In amongst the flint are various other pebbles from inland also washed down when the ice thawed. There are also pebbles left over from the large rocks used as ships ballast from the 13th Century until about the 18th Century.

Pebbles with holes, like the one above, are known as hagstones. They were once worn to protect the wearer from witches. They were also tied around the neck of cattle to prevent witches from riding them off to their secret meetings. Large pebbles with holes were tied at the bow of fishing boats to protect them from witchcraft.
