Introduction


When we started walking the coast of England we had no intention that this would become a major lifetime project. Having to make a last-minute arrangement for our summer holiday in 1987, we said "Let's go to the nearest piece of coast and see how far we can walk along it." It turned out well and we started adding further stretches of coast, initially once every two years, but soon annually, or even twice a year.

We had always enjoyed the coast - there is something refreshingly "edgy" about having the sea always at our side, and one of us was into marine molluscs. We also enjoyed long-distance walking and had long been involved in general natural history recording. This project enabled us to combine all three interests.

You soon discover when embarking on a project like this that you need a few rules, which evolve from the first experiences. Our main rule was that we should walk as close to the coast as possible, which meant beach-walking whenever we could (unlike the official coast paths that largely remain above shore, recognising that at high tides the beach may be inaccessible). The route should also be capable of being a continuous walk, so that when we came to an unfordable river we walked inland along its banks to the first place at which we could cross, whether a bridge or a ferry.

We only carried light packs, so that at the end of each day's walk we had the problem of getting back to our car where we started. Initially we walked back, but soon realised we would be walking the coast twice this way! We used public transport whenever this was available - buses or trains, sometimes adjusting our start and finish points to make this easier. Failing this - and it was often not possible - we would phone for a taxi (an increasingly costly option over the years). Having our car with us gave us more freedom as to where we could stay at night - and after a day walking and only light food we were usually ready for being spoiled by a good meal and a comfortable bed! Even so, we stayed on the coast itself whenever there was a decent option.

Each walk was made for enjoyment, it was not a route-march to see how quickly we could get it finished. We therefore took it gently at times when passing through pleasant scenery or where there were many plants or creatures to record.

In terms of biological recording, we systematically noted every bird, butterfly, creature or sea-shell that we came across, sometimes spending time searching for the shells. We could not record every plant in the same way - there are too many common ones - so we were more selective, noting all coastal plants and any others that were not run-of-the-mill.

In our daily posts, edited from our original diaries, we include a star-rating from no star to **** according to our subjective estimate as to how special that day was from the point of view of natural history. This score (and our daily records) will, however, have been affected by the weather - it is difficult to appreciate the environment fully, for instance, in torrential rain, and there are many more butterflies and other insects to be seen in warm sunshine!

Cornwall: Porthtowan to Perranporth 17/6/1999**

From the car-park at Porthtowan we crossed a small dune area with corn marigolds in flower and then had a stiff climb up out of Porthtowan, but there was a cooling breeze as clouds gathered.  On top the walk was level and easy.  At one headland there was short turf with a good show of dyer’s greenweed, red kidney vetch and spring squill seed-heads.  Approaching Chapelporth a lower path took us round the village and to a small beach with only odd fragments of mussel-shell.  At low tide it connects with Porthtowan Beach, but you would be lucky to match the time of the walk with the tides.  Climbing again to the National Trust cliff-top plateau we kept to the path nearest the sea and finally saw a raven and heard its plaintive low moan.  Jackdaws, rooks and carrion crows were also common, giving a tally of four black crows (pity the chough has gone).  Occasional cormorant and shag added to the sombre tally.  The heath vegetation is low with little cover for birds, so we heard only skylark this day and only got the odd glimpse of a linnet.  We found an unusual stilt-legged fly Calobata petronella and the local seed beetle that attacks birdsfoot trefoil, Bruchus loti. 
      There are disused mines all the way to Perranporth, the minerals producing basic rocks encouraging pockets of plants such as southern marsh orchid, fairy flax and yellow-wort.  The cliffs, quarries and mine-tips exhibit a huge range of colours and textures of rock.  At places the crumbling cliffs presented a desolate landscape redolent of desert canyons.  Beyond St. Agnes Head Chilean iris had escaped and was naturalised on the cliffs.  We descended into Trevaunance Cove, closest to the town of St. Agnes, and crossed the rocks between there and Trevellas Porth, saving a steep ascent and descent between two valleys.  There were good rock-pools here.  Spiral wrack was washed up on the beach.  A climb on the other side, past viper’s bugloss, led back to the cliff-top path, this time with Trevellas airfield on the landward side.  By one of the old runways was a plant of deep blue garden columbine, half a mile from the nearest house.  Also along the cliffs we found another patch of Euphrasia vigursii.  We finally rounded Droskyn Point to descend into Perranporth, with long views along Perran Beach and Penhale Sands.
