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: Poldhu to Porthleven 26/8/1998****

Portland spurge
From Poldhu we took the track to Church Cove, the second cove of that name on the Lizard.  This one lies below Gunwalloe Church, which seems to be built right on the sands and into the rocks of the cliff.  We found a great botanical rarity on the beach, sea knotgrass.  Washed up on the beach were dead pilchards.  There was plenty of sea rocket and sea holly on the dunes behind, but they were limited by a golf-course.  We crossed over the cliffs to Jangye-Ryn, a pebbly bay with dramatic contorted rocks.  After this the path went above the golf-course, through agricultural land and finally along a road.  Across the fields we could see the flag flying above Halzephron Inn as we dropped down to Porthleven Sands.  This is a line of shingle running all the way to Porthleven.  In the middle (Loe Bar) it blocks off the end of a ria or drowned valley, creating a large freshwater lake, Loe Pool, where we found 6-stamened waterwort.  The crumbly cliffs of slate, topped by a deep “head” deposit, held very little vegetation, mostly sea plantain, but was colonised by sand martins.  Loe Bar was also impoverished, but there was plenty of sea holly and yellow horned-poppy, with a little Portland spurge at the far western side.  A pale clouded yellow was flying – perhaps having just crossed the sea, and we also saw a grass eggar moth.  A group of people were making a commercial with elaborate props scattered over the foreshore.  We walked the final mile on soft unsupportive shingle with occasional rock outcrops.  The beach was not too busy, perhaps because there is little sand and the sea is separated from the beach by green weedy rocks.  We found tiny shells of the rare Parvicardium minimum.  Porthleven is quite plain and has a very long deep harbour.  The sun came out as we sat down to eat Roskilly’s local ice-creams before calling a taxi.
