Mud, mud, glorious mud!

Because of its very special nature in terms of habitats, biodiversity, species, geology and scenery, the Helford River has long been recognised as worthy of protection at both European and national levels. Fortunately our speaker, Kevan Cook, Lead Marine Adviser for Natural England, was able to guide us through some of the acronyms. The Fal-Helford SAC (Special Area of Conservation), lying west of a line from St Anthony Head to Manacle Point and giving the highest level of protection, is a European designation relating to habitats and some species.

At 6am, in the half light of a slightly misty hut dry morning. 15 persons converged on Goongillings Farm near Constantine to ioin Martin Rule and listen to the dawn chorus. Some of the birds were already in full voice. A wren interrupted its song to tick annoyance at the group and a chaffinch, likewise, gave vent to “spink-spink”. A wood pigeon cooed in the distance, more melodious than the pheasant’s harsh welcome to the new day.

Is that a pin-tailed duck? No, it’s a long-tailed duck. Isn’t that a gannet? No, it’s a black-tailed godwit. We were trying to identify birds on David Chapman’s jumper, knitted by his mother who had produced separate jerseys for different talks. His outdoor gear depended on conditions, one photograph showing military-style camouflaged top and trousers, plus a back-pack to carry a tripod, camera and lenses and a chest-pack containing a portable hide. When erected, the last looked like a camouflaged igloo, just large enough to accommodate David and Adrian Langdon for several hours bird watching at the Walmsley Reserve. His account of that outing was returned by Adrian with the comment that the phrase “the mud came nearly to the top of our wellies” had a typographical error in the final word!

After many years under the management of the Hodges family, in 2005 the Duchy of Cornwall Oyster Farm had been acquired by Ben Wright and Wright Bros Oyster Merchants. Ben gave a lively description of his current operations to rejuvenate the native oyster beds by lifting and cleaning all the stock, initially by hand – a daunting task but to be continued with a recently acquired oyster barge.

The term ‘plankton’ comes from a Greek word meaning ‘wanderer’ or ‘made to wander’,an apt description for creatures which drift at the mercy of winds and currents. Some are large and easily seen – the Macroplankton, such as jellyfish and the Portuguese man-o’-war. Others are small – the Microplankton, which measure a millimetre or so across – or less – and are studied using a microscope. These are collected with a conical fine-mesh net swept or towed through the water and they include a great variety of plants and animals, in adult or larval stages. There is a third, even smaller, size category – the Nanoplankton, such as coccolithophores, which are just a few microns across and only seen with the aid of an electron microscope.

Justin Whitehouse, National Trust Area Warden for the Lizard, first became associated with the National Trust as a volunteer shortly after graduating as a botanist and moving to Cornwall in 1994. His daily journey to work involved rowing across the river from Porth Navas to the office at Helford. Subsequently came five years work at Trelissick and then a return permanently to the Lizard, back to the woodlands and creeks that he preferred.
