The Shoreline Management Plan and Managed Realignment
It is salutary that, for aesthetic reasons, the community of Laugharne rejected the proposal to place a flood wall along the Strand across the back of the marsh, preferring instead to make its own local arrangements. The unwillingness to accept solutions dropped from above and to manage risk on the ground, as a matter of continuing adaptation is becoming a positive sign of community resilience, particularly when there is no immediate need for major infrastructure intervention.
Although the SMP2 recommendation for the medium term for the Malt House Marsh between Laugharne and Ginst Point is to set back the defences through managed realignment and create compensatory habitat against loss in other coastal locations, this would be at the expense of the current freshwater marsh habitat, and would disadvantage some of the existing commercial interests on the marshes. Given that the reclamation of the marshes between the 17th and 19th centuries took advantage of an area that was already accreting and therefore lent itself to “improvement”, and that the region continues to absorb more sediment than is either lost to tidal action or is necessary to balance sea level rise, it is debatable whether a managed realignment exercise would do more than what is effectively already happening through estuary processes, other than consolidate the levels already there. However, given future need for flood protection this could still become a consideration as a flood holding area.
Unlike the experience of the Dutch polderland, many historical reclamation projects in the UK took advantage of marshland that was either stable or already accreting; the incremental back barrier reclamation works are no exception to this: proof of the aggressive development of saltmarsh in the Lower Marsh area can be appreciated from an aerial photograph of 1946 by the RAF, where the comprehensive saltmarsh we see today appears as a vestigial presence at the head of the drainage channels seaward of the Freething Wall. Consistent with equivalent managed realignment projects, it is arguable that if this proposal is put into action, although it will establish continuity within the intertidal system it cannot fail to attract more sediment and rapidly stabilize of its own accord.
Thomas van Veelen, technical commentary:
The question of the effectiveness of managed realignment due to the progressive tendency of Laugharne Burrows to migrate eastwards and the continuing stability of those marshes already reclaimed, is a fair and interesting point. But first we should re-explore the goals of managed realignment from a flood protection perspective. These boil down to two key reasons, which are:
- The creation of a buffer zone by which the distance between land and sea is increased, thereby mitigating threat by the water body to the land (see technical commentary on Walley and bin Ishak). However, since the back barrier marshes are fundamentally farmland, this is strictly not applicable since they are inconsistent with a cost-benefit analysis.
- Where flood water storage is put in place to alleviate flood levels elsewhere, the additional available area increases the volume of water required to fill the estuary, potentially reducing the water levels upstream. However, when the water level rises faster outside than inside the estuary, velocities and discharge into the estuary may increase. This side effect may reduce the efficacy of the intervention. This is in contrast to fluvial flooding, where the supply of water is restricted to whatever amount happens to be within the system.
In a study of the macro-tidal Parrett estuary in Somerset, Prof. Nigel Pontee (2015) showed that managed realignment close to the mouth drew additional water into the estuary. A proportion of this was found to bypass the breach, raising water levels upstream. This dynamic is more pronounced for larger realignment sites, which significantly alter the tidal prism, and sites that flood quickly. Furthermore, a fully natural system would respond by widening the entrance thereby decreasing the effective extra storage. For the Taf Estuary, it would be feasible to mitigate this by stabilizing the spit, as carried out in the 1970’s by the MOD, but such an intervention would be counterproductive and not in the spirit of managed realignment.
The long-term benefits of managed realignment may be more subtle and linked to the stability of the marsh. A stable realigned Laugharne South Marsh would be more resistant to changes in the channel pattern, would reduce flow velocity and consequently benefit accretion of other marshes, particularly Laugharne Town Marsh, which in turn may further reduce storm impact.
Two further reasons why saltmarsh stability would benefit from managed realignment are:
- According to evidence derived from aerial photographs and from google earth, it appears that the 19th century reclamations advanced the line beyond the saltwater boundary of the marsh. It can be seen that creek networks have either become truncated by the floodwall or bend parallel to it. Since the elevations of the marshland ~3.60 m ODN are well below high spring tides ~5.20 m (Pye, from SMP2, Appendix C), under current conditions, the land behind the floodwall would be intertidal. In times, such as now, of foreshore retreat, the chances of survival increase when it can migrate backwards to retain a healthy sediment and seed supply (Fagherazzi et al. 2012). Effectively, the existing floodwall prevents this from happening.
- Since the closure of the Wytchett Brook, Railsgate Pill next to St. John’s Hill has become the main drain. After managed realignment, this would discharge directly onto the marsh, which would benefit from the increased sediment supply.
Managed realignment won’t stop scour and we still find it hard to quantify these processes, however the outcome is more likely to be positive than negative. According to Iris Moeller’s paper on the Freiston Marsh, the benefits to marsh stability after breaching exceeded expectations. It might be worth consulting other locations such as Alkborough Flats on the Humber or Steart Point on the Severn Estuary, which are also examples of ambitious managed realignment projects.
The parallel evolution of the community of Laugharn
Taking the comparison, of Turner’s dramatic painting of 1831 and David Cox’s painting of 1849 with photos from 1931, 1955 and the present day, the development of a mature saltmarsh across the frontage of Laugharne could well be a relatively recent phenomenon. Although the Barrier Spit may have created a degree of shelter and sympathetic conditions for extra farmland, ultimately, through siltation, it significantly limited seaborne access to the town and its harbour.
Gaining insight into a community through the lens of its landscape is fraught with pitfalls. To the outsider, it may seem counter-intuitive that the presence of a ballistic weapons research station at Pendine Burrows should be considered benign; yet locally it has become accepted as both an accustomed neighbour and a valued employer that supplements the economy of the district. Under other circumstances the prospect of unimpeded access to a continuous estuary landscape could be a driver for a sense of community ownership and responsibility for its wellbeing. But the lesson of living with locations as found can be much more persuasive than speculation upon what they might otherwise be. As it is for any other community, there is so much unforeseeable circumstance and unpredictable consequence that cause the story of Laugharne to slip in and out of focus in parallel to, rather than driven by, the conditioning effect of geomorphological change.
Rhetorical questions over the transformation of a community in the context of a changing landscape and how they reciprocally influence each other can never be resolved. A point of view set within a given landscape provides the “mise-en-scene” against which human stories are told. Being as applicable to any other small coastal town as to the community of Laugharne, the popularity of “Under Milk Wood” is in its universality, which testifies to the capability of a community to develop its own dynamic through the give and take of interpersonal behaviour, from which a collective and idiosyncratic identity evolves. This may be as loosely or closely connected to place just as are the characters in Steinbeck’s “Cannery Row” to their rundown waterfront neighbourhood in Monterey California.
Llaregyb: a limpid early morning. The fishermen adopt a characteristic indolence at the prospect going out to sea:
“But with blue lazy eyes the fishermen gaze at that milkmaid glistening water with no ruck or ripple as though it blew great guns and serpents and typhooned the town.
Too rough for fishing today.
And they thank God, and gob at a gull for good luck, and moss-slow and silent make their way uphill from the still still sea, towards the Sailors Arms.”
Men and women, wives, daughters and hopeful youths, melancholics and dreamers share for a night and a day and a night their fantasies and regrets, frustrations and hopes all organically bound as a collective unit within the cleft in the hills called Llaregyb, which could easily be Laugharne.
It is spring, moonless night in the small town, starless and bible-black, the cobblestreets silent and hunched, courters-and-rabbits wood limping down to the sloeblack, slow black, crow black, fishingboat-bobbing sea.
Hush, the babies are sleeping, the farmers, the fishers, the tradesmen and pensioners, cobbler, schoolteacher, postman and publican, the undertaker and the fancy woman, drunkard, dressmaker, preacher, policeman, the webfoot cocklewomen and the tidy wives.
This is anywhere and somewhere, it is a dislocated fiction born of a specific place which itself must be vivid enough to foster the myth. From this study it is clear that the conditions that encouraged human settlement were not to be forever and that the busy and strategic medieval port would, by the 20th century have fallen into genteel somnolence to re-awaken in the 1940’s as host and inspiration to the wider cultural world represented by Dylan Thomas and his friend Richard Hughes.
The lesson I have learned from Dylan Thomas is that although experience must be located in time, place and culture, it can never be so readily determined. A particular landscape may afford a context, but life carries on within it, answering to it but never prescribed by it.
The castle and the marsh:
The 1831 watercolour painting by William Turner of Laugharne Castle in a storm is a robust 19th century sublime man-and-nature vision of a tempest blowing “great guns”, with storm driven wreckage from some large ship cast ashore and scavengers braving the surf to retrieve it, in front of a suitably ruined castle as a backdrop. The poetry of this image is certainly a far cry from Dylan Thomas’s “milkmaid glistening water with no ruck or ripple”
. Although it responds as much to the genre of ruin ashore and wreckage at sea as to the location itself and notwithstanding Turner’s propensity for exaggeration, it begs the question of whether it may also be a verifiable document of the frontage of Laugharne beset by a particularly high storm tide.
Although in Turners time a high spring tide could still wash the footings of the castle, it is debatable whether this is a generic work or if it deliberately evokes the subliminal memory of other calamitous storm events, such as the great flood of 1607 that affected the Severn Estuary and the Welsh Coast as far west as the Three Rivers Estuary or even the Great Storm of 1703, which was of such severity as to cause the loss by 20% of the Naval Force at that time. Attractive though this might be as speculation, whether or not these events had an impact upon either the landscape or the psyche of the populace has proved unverifiable and my search within the archives of the corporation has so far not borne fruit. As a consequence all that remains is hearsay.
However, it is of interest that in the Laugharne parish archives, there is a small watercolour painting recording the wreck of the smack Sarah Anne Trehearne at Laugharne in 1836, which implies similar conditions to those exhibited in the painting by Turner just five years earlier. An indication of the height of the storm tide is that the owner of the vessel, John Griffiths, was drowned whilst trying to jump on board from the garden wall of Island House owned by Mrs Stackpoole. There is an inscription on this painting, sombrely recording both death and burial, signed by Jasper Nicholls Harrison, the Vicar of Laugharne at that time.
Harrison also wrote an epic poem “The Night on the Mast” in 1868, commemorating of the wreck of the schooner “Gem” of Hull on Laugharne Burrows in 1867.
Considering the question of veracity for both the Turner painting of Laugharne Castle and the record of the wreck of the Sarah Anne Trehearne, it is worth reminding ourselves that these come from a time before the development of photography and therefore express as much the embodied experience of a storm as its documented appearance. My assumption is that the sketch of the wreck is a surrogate for the event and the extreme weather conditions at that time rather a faithful record of it. For Turner, his famous painting “Snow Storm-Steamboat off a Harbour’s Mouth” of the 1840’s reflects the sensation of an elemental and immersive experience that also serves to evoke rather than record the event.
It is worthwhile noting that David Cox the landscape painter and much less flamboyant contemporary to Turner, concurred with him over the appearance of
the foreshore at Laugharne in the 19th century. I have located two images by Cox of gatherings on the beach, both of 1849: “Laugharne Castle at low tide, full moon rising” appears to represent a familiar activity such as cockle gathering, but the other has an urgency also driven by a storm event; a boat is being launched, perhaps to go to the aid of a ship in distress immediately offshore, whilst the bustle on the beach could be around a prone washed-up figure. As opposed to the scene described by Turner of wreckage being salvaged from the surf, this could reflect a more humanitarian response to emergency.

Although, according to our research, the bay has been steadily silting up since before Laugharne Castle was established in 1116, the visual evidence that I have gathered dating from 1740 onwards indicates a gradual transition. Originally an open port that allowed vessels to enter on the tide, lay alongside and dry out at low water, it is now an established saltmarsh with a creek system and a serpentine drain channel formed by the River Corran. Whilst this limits access it affords a greater degree of shelter for shallow dreft vessels. By the late medieval age the Pendine Burrows were accreting enough to create suitably sheltered conditions to exploit the transformation of the back barrier marsh into productive agricultural land, which was just when Laugharne was gaining strategic importance as a sheltered port with equal access to both its hinterland and to the sea.
By the 17th century, as landowners seized the opportunity to undertake reclamation works, the increased sediment load in the estuary was beginning to impact upon the capacity of the harbour at Laugharne. This period could be considered a transition point in the fortunes of the town, when the still active port of the 1740 view by Samuel and Nathaniel Buck, would become subject to rapid accretion and the growth of pioneer saltmarsh as apparent in a watercolour painting in the National Collection of Wales by an unknown 19th century artist. By 1887 it had become sufficiently well-established to be identified as a feature in the current ordnance survey map.

The period between 1660 and 1840 saw the greatest concentration of reclamation works, on both the East and West Laugharne Marsh. This is coeval with an acceleration in the propagation of saltmarsh not only across the frontage of the township of Laugharne but also in front of the Freething Wall (the final wall completed in 1810) on the foreshore that has now become Malt House Marsh. Take the right conditions, of a plentiful supply of sand overlaid by fine silts and estuarine mud, add the rich seed stock borne down on the ebb tide from upstream, it is remarkable how rapidly saltmarsh has propagated. Comparison of the early colonization of the vestigial saltmarsh on the foreshore at Laugharne South according to the aerial photographs of 1946 with the well-established saltmarsh site it has become now confounds the impression of permanence this area of marsh gives when viewed from the vantage point of Sir John’s Hill. This questions the fallibility of human memory and perhaps reinforces the suspicion that these marsh landscapes are fundamentally deceitful and treacherous.
An engraving of Laugharne Castle at low water in 1835 by Henry Gastinau and one at high water by George Hollis of 1839 lend credibility to the paintings by Turner and Cox. Together they testify to a rough and stony foreshore regularly covered at high tide tide up to the footings of the castle. Further examination of the Gastineau image reveals a strand line from which a man is filling a wheelbarrow using a pointed spade: whether this is bait digging, collecting cockles or seaweed is not clear but it is evidently a familiar enough sight to also appear as a component in the low tide painting by David Cox.
From the late 19th century and into the 20th century an increasing amount of photographic material documents the comprehensive colonization by saltmarsh of the foreshore of Laugharne. Although it is not always easy to date these photographs, the increasingly luxuriant foliage around the castle and the type of vessel moored in the channel provide clues. The earliest image that I have found is probably from the late 19th
century, in which at least four chunky trading smacks lay dried out in the pool inside the saltmarsh.
These could be any of the vessels owned at that time in Laugharne, such as the Lively, Skidaddle, the Brothers, Sarah Ann, Nautilus
or the Towy
, which all traded as far afield as Bristol and the channel ports and are typical of the trading vessels seen in any 19th century photographs of Welsh coastal ports, handy enough to navigate into small coastal havens but sturdy enough to weather the rough seas and exposed coast of West Wales and the Bristol Channel. Well into the 20th century there was still a carrying trade from Laugharne with cargoes such as road stone to Carmarthen and coals from Kidwelly.
This is a matter-of-fact image, the vessels are unromantic the shore is a hard, shelly, shingly constituency, not yet sheathed in estuarine mud as it is today. In an image of 1907, another typical coastal trading smack lies moored up in the creek, by which time the saltmarsh sward has become established but the difference between the height of the marsh and the bed of the creek remains modest. . By the late 1920’s and 30’s the relics of this fleet may still be seen particularly in the photographs of Francis Frith, against a castle now festooned with ivy and a well established saltmarsh before it.
Since then the mass of the saltmarsh has increased, but the macrotidal nature of the estuary and the presence of the River Corran has ensured that the navigable channel system remains scoured clear. In this sense it is safe to say that sheltered moorings are likely to continue as a feature within the saltmarsh for the foreseeable future no matter how much it may expand. Indeed at present, it appears to have reached equilibrium, since it is in direct competition with the main ebb channel of the River Taf that limits further progradation of the marsh into the estuary through the effects of erosion. Given that the relationship between settlement and foreshore is fundamental to the history of Laugharne, its very success and continued development may have contributed to the gradual shift of attention away from the estuary as its raison d’etre. Habits of life and livelihoods must have been compromised by the de facto role the River Corran and the intertidal area must have played in the disposal of waste. In common with many estuarine settlements, drainage eventually finds its way to the foreshore to be dispersed by the tide. It is certain that Laugharne would have been no exception and both domestic and agricultural waste would have entered the Corran and thence into the Taf. Even the installation in the 20th century of an outfall pipe across the marsh to discharge sewage closer to the tideway must have been an unsatisfactory solution since this was to be replaced in the 1970’s by the sewage treatment plant under Sir John’s Hill. However, according to my colleague Lian Lundy Professor of Environmental Science at Middlesex University
“this all could have been due to legislation e.g. urban waste water treatment directive requiring sewage treatment plants for all populations above a certain size. This was 1991 but there must have been some requirements before that”.
I have discussed the likelihood that the increase in the size of the settlement in the 19th and 20th centuries necessitated a more orthodox approach to wastewater management by discharging directly into the tideway, which may have created a more salubrious foreshore but may not have made much difference to the nutrient load received by the marsh. I queried whether there may be evidence of this in the type of saltmarsh vegetation and its distribution within the marsh and whether a nutrient rich environment may have served to promote its propagation or not. It would be a neat proposal that the settlement itself might inadvertently have aided the conditions for the generation of a healthy marsh, however upon reflection this is more than outweighed by the sheer amount of sediment in the system and a plentiful supply of estuarine muds to overlay it.
This is confirmed by Tom Fairchild, who is a marine ecologist, undertaking extensive analysis of the saltmarshes on the Taf for this project: he assures me that it is unlikely that input of nutrients into the system will have had any appreciable impact upon the composition of the marsh:
“My general thoughts on this are they probably would have a negligible effect. Considering the size of population that the sewage discharge would come from, the predominant use of land for agriculture (particularly livestock), and the short residency due to macrotidal regime, I wouldn’t imagine that effects would be large. I have also seen no specific evidence of this on the shores, with differences in vegetation forming more along wave stress and height gradients. There is also no direct evidence to suggest that enrichment at expected low levels would affect growth significantly (so far as I know), but instead may lead to contraction of marshes if loading is high enough by reducing investment in belowground root structures”
Although it may be doubtful that increased nutrient loading of the system may have impacted upon the composition of the saltmarsh, the awareness of the outfall in this location could well have a bearing upon the community perception of the saltmarsh as asset or liability. Whether it is an issue or not, the idea of an area that may be bathed in sewage twice a day just outside of your front door is perhaps enough of a disincentive to become engaged with it. Certainly the untutored and popular understanding of saltmarsh can be that it is both dirty and hazardous and therefore to be avoided.
Fishing has been a major occupation in various guises at Laugharne since medieval times, but has been in decline over the past century. The practice near the entrance to the Gwendreath and Towy Rivers was to exploit stony ground close inshore to set up permanent fish weirs taking advantage of the high tidal range and easy accessibility from the shore. These grounds were known as “Scars” and include Salmon Scar, Pastoun Scar, St Ismael’s Scar and Ebb Scar.
In contrast to Black Scar on the Pentowyn shore directly opposite Laugharne town, the ground on the Laugharne side of the estuary is both too soft and too mobile to keep a fixed configuration for a fish weir and therefore did not lend
itself to permanent structures. However quite similar passive strategies to fish weirs were adopted through deploying nets manually over a single tide. This gave rise to the use of a range of techniques adapted to particular conditions, locations and species: these ranged from Back Nets, long low nets staked along the shore to trap fish left behind by the ebbing tide, Stream Nets, set directly in the tidal stream, Heave/Haft Nets managed by hand in the tidal stream to catch salmon, Wade Nets hauled along parallel to the shore by two men and Seine Nets which are long nets fixed to a point ashore, stretched out by boat in a curve before returning ashore at another point to be pulled in.
All of these techniques relied upon access to firm hard sand on the immediate shoreline. When this became covered in soft muds due to increasing sedimentation of the estuary and fish stocks depleted due to overfishing, the fishery diminished. Very much the same happened with the cockle industry. As the inshore cockle beds became smothered in silt, it was no longer possible to take a donkey cart on to the sand to load cockles and so boats had to be used to access the beds further out in the estuary towards Ginst Point as the tide permitted. Eventually over recent years, due to overfishing and a disease that severely affected the stocks, cockle gathering has ceased for the time being.
It is debatable how much the silting up of the estuary and proliferation of saltmarsh, particularly at Laugharne contributed to the decline of the fishery, but suffice it to say that it was coincidental. I have taken much of the information upon the fisheries from “Laugharne, Local History and Folklore” by Robert Henry Tyler, 1925, when, apparently commercial cockle picking was still thriving albeit driven away from the foreshore to the outlying sandbanks. There is an image in the Francis Frith collection dated 1955 of fishing boats drawn up on the quay still rigged to sail, they are locally registered, one of which is easily legible as LA54. Other fishing activity in the estuary tends to be predominantly leisure fishing for sewin (sea trout) and salmon by rod and line from a boat.
Although it can be surmised that the incremental growth of the saltmarsh deprived the town of both beach and harbor and landlocked its castle, this process will have coincided with the development of road and rail communication as an alternative to reliance upon a port facility and access to the sea. By way of compensation, the increased extent of the saltmarsh provides the ecosystem service benefit of protection from wave action and fetch from the southeast and therefore to an extent, mitigates the effects of storm driven wave action upon the houses facing the saltmarsh.
Access and Amenity:
Public access to the Taf estuary landscape has become limited for various reasons and it is reasonable to argue that the seeming capriciousness of saltmarsh might be a factor in this. It is quite correct that the denizens of these landscapes tend to be those who value them most. Others keep a safe distance. It is a less difficult task convincing people of the value of saltmarsh than enticing them out on it. With this in mind those paths that stick to high ground or follow established tracks are inclined to be those that are most well trodden. I have drawn the following points from the body of this study to summarise issues that have arisen relating to access:
- For Laugharne, the term Green Banks coined for the municipally managed upper saltmarsh area, betokens a demure and benign landscape, more befitting a leisured well-to-do neighbourhood than a bustling port. But this establishes a territorial limit beyond which, whilst benefitting from the view, the wildlife and the buffer zone that it represents in a storm event, it may be deemed unwise to venture further out into the saltmarsh.
- For both Laugharne Town Marsh and Malt House Marsh we have established that, given their sensitivity to shifting estuarine behaviour and that, covered by the tide twice daily, they are essentially inconsistent, there may be a disinclination to venture out unless well prepared. In reality it is those denizens of the marsh such as the fishermen, wildfowlers and foragers (and of course the odd marine ecologist) who have intimate knowledge of these sites. For the rest of us, it has become predominantly a detached visual experience from a safe vantage point.
- The presence of the weapons research site is possibly sufficient disincentive to venture out upon Malt House Marsh. According to the ordnance survey map there is a footpath from Salt House Farm to East House at the edge of Laugharne Burrows and from there, following the edge of the exclusion zone via New House to Malt House Marsh, but the final section along the top of the 1660 wall built by Sir Sackville Crowe is so overgrown as to prove impassable. According to the map this is where the path stops, although it is perfectly possible to either take a track back to Salthouse Farm where it follows the remainder of the 1660 wall or to take the seaward edge of the Freething Wall back to Railsgate Pill and Sir Johns Hill. However, the impassability of the section along the 1660 wall is indication enough that this particular section of the footpath has been neither valued nor used by the public over a long period of time. However, when the ballistics site is not in use in the evening and at weekends, it is also well frequented by the local community who can also gain access via the Freething Wall to Ginst Point. In other respects, the far west end of the burrows complex at Pendine remains a major visitor attraction (but not for its saltmarsh).
- The argument that the use of marginal land by the MOD and the exclusion of public access are normally beneficial to biodiversity is well rehearsed. Although collaboration with local and national organisations to conserve and maintain habitat is a positive gesture, this still imposes limitations upon access to the broader landscape. It is neither the intention, nor within the scope of this paper to discuss the limitations imposed upon access by a weapons testing area, but also for the sake of the study it is appropriate to acknowledge that this is an influence upon the overall perception by the community of its immediate landscape. There are of course other constraints, including potential unexploded ordinance hazard inherent to the landscape, that affect whether or not it welcomes access:
- Both the Pendine and Burry Port ranges impose restrictions to navigation in Carmarthen Bay and in particular at the entrance of the Three Rivers Estuary. As a consequence sailors have to notify both sites by VHF of their intentions to request access. MOD vessels constantly patrol the area. Taken together with an already hazardous entry these represent a disincentive to both commercial and recreational navigation.
- It is understandable that the less a community is focused upon the foreshore for its livelihood the more disinclined it is to engage in it (unless of course it also happens to be a recreational beach). However, in an interesting gesture of self-determination, the community of Laugharne decided not to accept the NRW (Environment Agency Wales) proposal to install a permanent floodwall across its frontage for the reason that it would compromise the experience of the landscape. In a move that may need reconsideration in future the decision by the community to live with threat and adapt to it rather than expect a benign authority to manage it upon its behalf, is encouraging.
- Given that access to the fresh and salt marshes towards the Burrows is either compromised or not attractive and the town marsh very limited, the key footpath is the Welsh Coast Path, which follows the Taf and therefore overlooks its fringing saltmarshes, taking the road across the landward edge of the Town Marsh and via Sir John’s Hill (Dylan Thomas’s Birthday Walk), it gives a stupendous view of the estuary and the extensive Malt House Marsh. But, apart from evening and weekend access to Laugharne Burrows, this is about as far as the designated provision of access goes, imposing a detached and disengaged experience of landscape and laying emphasis upon the experience of the panoramic views.
Myth, Conjecture and Obfuscation:
In a place so full of history and especially on the West Coast of Wales where oral traditions are strong, it is small wonder that writers such as Dylan Thomas put down roots. Without specifically addressing place it is significant that Laugharne debatably became his muse in the creation of Under Milk Wood and that in turn the community adopted him as a son. It is no small coincidence that when I asked two wildfowlers who I met on the town marsh about the cockle industry, I was told that I needed to talk to Barry Cockle.
In a letter to the novelist Richard Hughes in 1939, Thomas tells him that “what Laugharne really needs is a play about well-known Laugharne characters – and get them all to play themselves”; but strictly speaking, Under Milkwood is a lesson in the capability of communities to transcend time and space and, as discussed, should not be taken as intrinsically bound to place. Just so, in his novel, “In Hazard” written whilst living at Castle House in Laugharne, Richard Hughes based an examination of the behaviour of the crew of a ship, the Archimedes, beset by a Caribbean Hurricane upon the true story of SS Phemius caught up in the 1932 Cuban Hurricane. The common ground shared with Dylan Thomas is in the use of a circumscribed community as a device to suspend a study of human interaction. But, as can be seen in a letter from Thomas to Marguerite Caetani in 1951, this is where their respective intentions diverged:
“the idea (is) that I write a piece, a play, an impression for voices, an entertainment out of the town I live in, and to write it simply and warmly and comically, with lots of movement and varieties of moods, so that, at many levels, through sight and speech, description and dialogue, evocation and parody, you come to know the town as an inhabitant of it.”
Against this Hughes narrative is much more driven by the question of how a highly regulated and structured community copes with the extraordinary experience of complete loss of control and is therefore a more taut, urgent and unsparing work.
Laugharne has evidently taken Dylan Thomas to its heart and has built a mythology and, of course, a tourist attraction around him, very much like the way in which Benjamin Britten has become an institution for Aldeburgh in Suffolk. On the instigation of Bob Stevens, Mayor of Laugharne in 2014, the path used by the cockle girls when stranded by the high tide, over Sir John’s Hill to Laugharne, was rebranded as Dylan Thomas’s Birthday Walk and his “Poem in October” was duly installed on a board overlooking the estuary, the marshes and beyond to Carmarthen Bay.
To further digress: on the same walk there is a mysterious plaque that for the unwary, purports to explain the formation of the marshes below. Nowhere is the sense of willing obfuscation more apparent. Although the title: “The Gathering at the Llareggub” nods towards Dylan Thomas, thereon, it departs into a realm of barely plausible fantasy. “The Unsoiling of the Rockall” is the product of an elaborate global exercise, by the artist, Dimitrios Eames to create a parallel universe called Kcmaerxthaere. The partner to this plaque is fixed to the seabed 45 feet down in the Garvellach Islands of Scotland. The fortuitous rescue of the plaque from a skip and its location on Dylan Thomas’s birthday walk is another initiative by Bob Stevens.
In spite of the small size of the community of Laugharne, it appears to have been moulded by a surprisingly broad amalgam of influences. Apart from the silting up of the harbour, these are as various as the effect of Sir John Perrot one-time incumbent of the lordship of Laugharne and who is remembered in Sir John’s Hill as an ironic reference to his propensity for claiming any common land that he could lay his hands on, or the subsequent ruin that his elegant tudor mansion became in 1644 as a result of the civil war. Like any other ancient landscape, Laugharne is the result of all that has happened in and beyond its boundaries, not all of which is even traceable: the possibility that there may be residual memory of extreme events such as the Great Flood of 1607 is intriguing, and although not at present verifiable, it has been cited on the Dylan Thomas Boathouse website as a possible tipping point for the incremental silting up of Laugharne harbour, linking it to the construction of a quay closer to the main tideway in front of the boathouse:
“These two facts suggest that when the port of Laugharne in front of the castle became silted up after a tsunami devastated the Bristol Channel in 1607, the area around the Boathouse became important for the shipping of goods and ferrying of passengers.”
The tsunami theory may be an attractive proposal, but with reference to the description earlier in this document of the influence upon Laugharne of the progradation of Pendine and Laugharne Burrows, there is no concrete evidence to give an alternative interpretation of the build up of sediment in Laugharne Harbour to that of a centuries-long incremental process.
Irrespective of its verifiability, the implication that Laugharne might be struck by a cataclysmic event as depicted by Turner could be embedded in the psyche of the community. It is certainly conceivable that under certain fluke circumstances, when conditions combine, huge surge tides can occur and could sweep unimpeded into the town. Just as in the Turner painting, an exceptional event may overwhelm the capacity of the saltmarsh to attenuate storm driven waves.
Small communities cherish the narratives that contribute to their identity and Laugharne is no exception. Apart from London, it has the distinction of being the only surviving medieval corporation, dating back to 1291. Unsurprisingly it has some particular rituals that support the sense of its uniqueness, such as the Common Walk, essentially a version of beating the bounds, it takes place every three years on Whit Monday, and is a notoriously bibulous and boisterous affair. By all accounts this event is worthy of Dylan Thomas whose story has been considered synonymous with that of Laugharne for over half a century. Although I have proposed Under Milk Wood as a useful model for how communities define their own trajectories, either within or without their landscape; it is only through a heightened sense of ownership and belonging acquired through the stories that inhabit it can they become initiates to their own mysteries.
The Living Memory of the Dead
Through this text I have sought to explore the mutual affect of the evolution of a landscape and the transformation its community has undergone. Although it is certain that there is a degree of anthropogenic causation in the formation of the saltmarsh complex within the Taf Estuary, this is not so much in the process itself but more in the rate at which it has happened. It is demonstrable that the sedimentation of the estuary has been driven by the progradation of the Pendine/Laugharne dune barrier, but the consolidation of this through engineering and reclamation works since the 17th century and the further constriction of the mouth of the Three Rivers Estuary may have accelerated the process and the consequent formation of the saltmarsh in front of Laugharne.
With reference to the studies of the Pendine Barrier by Stuart Walley in 1996 and of the sedimentation of the Taf Estuary by Abdul Kadir bin Ishak in 1997, together with visual and anecdotal evidence gathered by myself, I have acquired greater familiarity with the symbiotic relationship between the geomorphology of the Taf Estuary and the degree that this has coincided with the human history of the area. Although in the first instance, the estuary system provided appropriate conditions to enable settlement and to establish a thriving community, as this continued to evolve it started to foreclose the capacity of the harbour to be operable and for the village to remain strategically a hub for the region. However, it must be understood that this has been such an incremental process that although in epochal terms the development of saltmarsh both at Malt House Marsh and across the frontage of Laugharne has been rapid, in terms of individual human memory, it is slow enough to have barely registered.
On this basis I would suggest that the question of benefit or disbenefit that saltmarsh might bring to this particular community is moderated by the sense that it is perceived as a part of the condition of the landscape and is therefore lived with. Living in the continuing present, in spite of the prognosis of the SMP2, severe change is not considered imminent and any threat such as sea level rise, so gradual as to be accommodated for the time being by home grown solutions. This disparity of view is implicit in the use by government agencies of epochs as a determinant of perceived levels of risk set against the cycle of a community’s experience of located time and the remoteness of a sense of long-term change.
For Laugharne as a community with a livelihood that was once tied closely to its estuary, there is now very little evidence of commercial benefit derived from its location other than from tourism. Admittedly the landscape makes it a wonderful place to live in and it is very popular, particularly for visitors and for retirement, but apart from a limited number of jobs available with Qinetiq at Pendine, seasonal holiday work, and commuting to Carmarthen, there is little other occupation within the town itself. Since very few people have the purpose or the inclination to venture out upon them any more, I question whether for the community, there is much engaged interest in the two main local saltmarsh sites beyond how they enrich the view. For the farmers who graze stock on them, the wildfowlers who shoot upon them and the boat owners who have sheltered moorings in the town saltmarsh, there is a more profound understanding of the marsh, its condition, the tidal cycle, changes induced by weather conditions and the fluctuation of the main ebb channel of the Taf across the estuary.
Inevitably in an interdisciplinary investigation such as CoastWEB, there is so much that is a matter of surmise since, although the scientific data has been exhaustively gathered and the history of the community well documented, definitive links between the two remain confined to the living memory of the dead. Given a theme so nebulous as the perceived value of saltmarsh from a community point of view and the elusiveness of specific historical data, the range of disciplinary expertise applied to the study may serve to illuminate the lacuna between data, knowledge and the degree to which they affect day to day living, but can only make sense when drawn together in an integrated and holistic study. It is axiomatic that whatever research tool is applied to a subject will reveal yet another level of data, by its nature, mine must be a serendipitous process that continually feeds from and intersects with other investigative modes; whatever I discover can only be applicable if it is grounded in and reflects the broader scientific characteristics of the study, which inevitably means that there must be a strong symbiosis between our respective methodological frameworks that act to support, extend, corroborate or confound my own interpretation of statistical, documentary and cultural evidence.
Albeit informed by hard won data, the community’s perception of its immediate environment is the crucible in which this study must be tried. In turn this perception relies upon the condition and identity of the community itself, and is essentially poetic. However rigorous our method may be, it can never be any more than a map of the broader context, which, subject to circumstance, is circumscribed by the caprice of human nature.
“Less than five hundred souls inhabit the three quaint streets and the few narrow by-lanes and scattered farmsteads that constitute this small, decaying watering-place which may, indeed be called a ‘backwater of life’ without disrespect to its natives who possess, to this day, a salty individuality of their own.”
For me this has been an exercise in linking what is believed to what is known and how public perception is an affect of cultural circumstance as much as physical condition. What follows is a list of understood conditions from which certain conclusions might be drawn.
What we have established:
- The Taf is a macrotidal estuary (high tidal range)
- The Pendine/Laugharne Dune Barrier continues to prograde and Ginst Point to migrate eastwards.
- The constrained entrance to the estuary has a throttle affect upon tidal exchange.
- Consequently, due to deposition of sediment at the entrance of the estuary, the tidal cycle is asymmetric. The result of is that the flood rise when it enters the estuary is faster than the ebb.
- As a result the estuary is flood dominant, exacerbating the tendency for sediment not to leave the estuary on the ebb
- The incremental sedimentation of the Three Rivers Estuary and in particular the Taf, has been taking place for at least a millennium, albeit the cycles of erosion and deposition will have not remained consistent over this time.
- Initially this was experienced as an advantage, permitting the establishment of a sheltered haven and strategic strongpoint at Laugharne and providing suitable conditions for reclamation of salt marsh land behind in the shelter of the dune barrier.
- Subsequently this has caused the continuing formation of saltmarsh on the seaward side of the last reclamation in 1810 at Malt House Marsh and within the embayment across the frontage of Laugharne causing the incremental sedimentation of the access into the town marsh from the estuary.
- Although the growth of saltmarsh has been rapid in geological time, it has also been experienced across generations and noticed over individual lifetimes.
What else we know:
- There was a surge tide event in 1607 that had a major impact upon the South Wales Coast and Bristol Channel ports, which may have had an impact upon sedimentation in the Taf Estuary.
- There exist photographs from the 19th century of substantial vessels drawing up to and over 1.5m, moored up in the tidal basin formed in the River Corran beside the Strand, which is a relic of the previous harbour. According to photographic evidence, this practice continued well into the 1930’s although, by the unrigged condition of the vessels, it appears that the site may have been either used for laying-up or for sheltered winter storage. These images also testify to the depth of the estuary and the navigability of the shoals at its entrance during those times.
- Due to the tidal range it is unlikely that vessels ever laid afloat at Laugharne through an entire tidal cycle and as a consequence took the ground at low water.
- Although the use of the saltmarsh channel complex at Laugharne continues to be exploited as a sheltered mooring for shallow draught boats, this remains limited by the tide and is becoming increasingly difficult.
- By the early 1900’s the use of the quay had become increasingly constrained for landing cargoes of coal and in 1913, a quay was constructed in front of Dylan Thomas’s Boathouse to facilitate access for vessels of deeper draught.
- According to the OS map, ordinary high tides reach the edge of the Strand
- There is continuing evidence of high storm tides reaching beyond the Strand at Laugharne well into the 19th century to the present day. The vulnerability to tidal flooding of the properties along the frontage of Laugharne remains of sufficient concern to have been included in SMP2.
- Although access to Ginst Point and Laugharne Burrows is permitted, this is only when the Cinetiq site is not in operation during evenings and weekends.
- The footpath between complex across the East and West Marshes is disjointed or fallen sufficiently out of use to discourage access.
- Although the proposal that the 1607 storm surge was a tipping point in the silting up of Laugharne harbour appears as a claim in www.dylanthomasboathouse.com, I have been unable to identify any supporting evidence for this.
- There may be a point in the future when the tidal and fluvial system of the Taf will stabilize, when the scouring and re-suspension of sediment through the effects of scour on the ebb, may balance the amount of deposition on the flood.
- Alternatively the increased constriction of the estuary mouth and increased sedimentation may increase tidal velocities at the entrance and lower tidal range further within the estuary.
What this means for the community:
- Although there is a history in the area of living with saltmarsh, a key occupation linked with the intertidal zone was cockle picking which happened on the foreshore and on tidal flats at low water. At present, this does not take place close to the town and even at sites such as Ginst Point it is banned due to disease and stock level issues.
- Further historical activities include the import of coal until road transport took over, fisheries, foraging for marsh vegetation, and the unusual creation of burning fuel through a mixture of coal dust bound in mud.
- The marsh at Laugharne still provides shelter for recreational vessels, particularly those used for angling. As above, this is becoming increasingly constrained by the tides and depth of water in the channels.
- A local farmer grazes stock upon the Malt House Marsh. This is mainly sheep but also cattle. These tend not to venture beyond the high marsh grassland. This area becomes heavily trampled, which makes walking along the seaward side of the Freething Wall difficult.
- Unlike other locations such as the East Anglian Coast, the saltmarsh is not extensive enough to become an independent landscape with its own distinct culture and society. Although on the Taf it has a material influence upon the way of life by cutting the community off from direct access to the estuary and historically by providing land of a suitable elevation for reclamation, the link it has with local culture depends upon the degree of habituation to it, individual livelihood, family memory and association.
- In other locations, saltmarsh is frequently considered alien and unclean. This may be exacerbated by the suspicion that the muds could harbour human and agricultural waste passing through and into the estuary. It represents a transitional zone between what can be controlled and what cannot. It remains a matter of conjecture whether this view can be applied to Laugharne.
- Conversely saltmarsh is an accepted part of a place, something to be habituated to, disliked by some but cherished by others.
- Although it may be appreciated that saltmarsh is an asset and a resource, it is debatable how much it is valued as such by the local community. It is appreciated however that the presence of saltmarsh will act to attenuate storm driven wave and tidal action and their impact upon the low lying properties at the Grist and along the Strand.
- It is however valued as a safe mooring for boats. Laugharne Corporation manages the moorings and grants the licenses for them
Transferability of findings to the Mawddach case study site:
- Although it is intended to reflect upon a broad range of Welsh coastal landscapes through the use of the Taf and the Mawddach Estuaries as case study sites, it is in their nature that some material will be transferable and some will not. From the start of this summary, it is clear that whilst some generic lessons may be drawn, many of the characteristics of both Laugharne and its situation upon the Taf are utterly unique. In this respect, caution must be exercised when applying principles of saltmarsh generation as experienced on the Taf to other estuarine locations.
- The tidal range at max 5m on the Mawddach is not so extreme as on the Taf at 8m.
- Although both the saltmarshes on the Taf and the Mawddach are grazed, this tends to be restricted to the upper marsh on the Taf, possibly due to its higher tidal range.
- There will be some merit in the comparing and contrasting the two case study sites since the dynamic of the Mawddach Estuary is also distinctive. Although both estuaries respond to a constrained entrance and correspondingly a high degree of sedimentation, the similarities do not go much further than that. How this is manifested is unique to both systems.
- The drivers for socio-economic development on both the Taf and Mawddach are also particular and will benefit from further study. These include characteristics such as the location of the salt marsh sites in relation to the development of harbour facility, the shelter afforded by coastal features such as the dune barrier at Pendine and the Ro Wen Spit at Fairbourne, the degree of exposure to storm action and the relative vulnerability to fluvial discharge.
- In order that compatibility may be established between The Taf and Mawddach Estuaries and to allow applicability to other coastal sites, I intend to establish a consistent methodology, which for me must be anchored in an understanding of the estuary system and work in tandem with a reflection upon the history of the community and the degree to which this has evolved reciprocally with changes in the intertidal zone with a particular reference to saltmarsh.
