U3A Botany Group - Aug 2018

Peter, Jean, Moira, Trevor, Fiona ,Rosey and Margaret met in showery weather. We looked at the area around the car park, along the base of the cliffs as far as the beach at very high tide, then along the main track through the dunes, ending at my house for refreshments. Folk commented on the build up of the dunes over not many years, the current sand deposition on the beach, and the commercial sand extraction. We were dismayed by the amount of dog pooh, but amazed at the number of snails we saw, of many sizes and colours.
The area was mainly colonised by Lyme and Marram grasses, with a few patches of Sea couch grass.
Plants identified were:-
Sea and Ribwort plantain Sea rocket Curled dock Smooth and Prickly sowthistle Sea mayweed Pineapple mayweed Red poppy, Silverweed Catsear Scots lovage Shepherds purse Cow parsley Hogweed Angelica Common chickweed Sea sandwort Red and White clover Knapweed White bindweed Meadow sweet Flag iris Coltsfoot Lady's bedstraw Sainfoin -not a native plant, probably deliberately planted below the Viking, Red campion dandelion daisy Meadow buttercup Common and Frosted oraches Tufted vetch Meadow Vetchling Ground elder Rosa Rogosa Rosebay willowherb Common nettle Sea thrift Spear thistle Creeping thistle Yarrow Birdsfoot trefoil Oysterplant -3 patches- one damaged by a camp fire, but starting to recover Horsetail Ragwort.
