Cilfái: The History and Heritage Features on Kilvey Hill, Swansea ISBN 978-1-7393533-2-2

‘I don’t know why you all get worked up about it…there’s nothing up there’
(Swansea Council employee 2022)

This final Cilfái study was a bit more challenging than I first realised. I thought I had a good impression of the hill’s history and landscape. That was until I consulted the official records that were sadly inconsistent or often compiled with little knowledge or experience of the hill. This meant that this book and its lists were far more of a collaborative effort than the earlier books. This was no bad thing as I made or renewed friendships far and wide as spent more time on the hill connecting with the land and people. My grateful thanks and appreciation go out to all those who gave freely of their time to talk to me about their views and ambitions for the hill. This is particularly true of the features listed in the Modern History chapter, which, for many, is their whole experience of the hill. Unfortunately, the hill’s archaeological knowledge is poor, but that may be because there is more to discover, and we can be optimistic about that, as archaeologists frequently must be.


The Kilvey Woodland Volunteers are the lifeblood of the Cilfái community, and I’d like to thank Marian Francis for her support and commitment to all of us who work on the hill. Equally, the wider community who have planted so much and built The Glade and the Roundhouse and who contribute to so many well-being and craft activities on the hill have been truly inspiring in their unsung work on the hill for local people.
Once again, I need to acknowledge the help of Gerald Gabb in some of the Gwyndy story for me, and the support of library and archive services has been invaluable. The conversations with my old archaeologist friend John Andrew are always supportive. At the time of writing, I have no idea when or if the destruction threatened by Swansea Council will occur. I hope the lists in this book guide and support everybody who wants to care for and preserve what is on the hill. And yes, in answer to that nameless person who I quoted at the top of this page, there is plenty up there. You just have to care enough to look, and talk to the local community.

Cilfái: Woodland Management and Climate Change on Kilvey Hill, Swansea ISBN 978-1-7393533-1-5

This has now been reprinted as a 2025 Second Edition with some updates I’ve also updated the copyright for AI constraints, and EU product compliance details.

This book started out as a collection of notes made over more than a decade of surveys in Welsh woodlands. What started out as a historical investigation into industrial archaeology in woodlands transformed into a catalogue of what climate change, government policy and local politics is doing to our landscape. As I write this Cilfái is threatened once more with proposed transformation that increasingly looks like destruction.


This is a companion volume to Cilfái: Historical Geography on Kilvey Hill, Swansea. But this one is more about the environment of the woods and the climate change that is already changing the nature of the land. Climate change is now part of life and the next generation will be challenged with adaptation to what is happening. This book is my chronicle of what some of that means for Cilfái (Kilvey), this most special part of Swansea’s character that has been abused, ignored and loved…depending on where you live and what your politics are. Some of this work is based on my government experience as a programme reviewer of many environmental and cultural projects across the UK where I experienced the good, the bad, and the ugly of politicians, the Civil Service and successive government policies or the lack of them.


Authors always have inspiration from somewhere and I am no different. My inspiration has been in the conversations and actions of many colleagues in my time working in UK Government in Defra, MOD, Cabinet Office, and Parliament. They all contributed, sometimes unwittingly. You can often learn a lot about a topic by listening to people who know very little about it but who never feel restricted in holding an opinion. Climate change is one of those topics.
I have been privileged to have had the company of experts in many conversations about the topics covered here. But notably, the Forestry Commission was laid bare to me by veteran forestry man David Connick. Equally, the passion of my friend Keith Clement in worrying about where we are going has constantly coloured my sense of urgency.
The commitment and enduring engagement of the Kilvey Woodland Volunteers never ceases to amaze and inspire, and I regularly see incredible generous acts of sharing and care for the Hill that should be an example to all volunteer groups.

I produced or maspped a lot of data (both historical and current) using QGIS. Here you can see the 1980s woodland compartments and their relationship with the original industrial waste tips.

Cilfái: Historical Geography on Kilvey Hill, Swansea ISBN 978-1-7393533-0-8

This has now been reissued as a 2025 Second Edition with some updates, minor amendments and some new illustrations. I’ve also updated the copyright and EU product compliance details.

This study has been heavily reliant on past teaching notes and lessons learned from students’ questions and discussions over many years. I am indebted to all of them. Grateful thanks to the staff of West Glamorgan Archives Service and the archivists at the British Geological Survey in Keyworth who allowed me to spend time with William Logan’s original notebooks. The help of experts such as Dr John Alban and Gerald Gabb has always been beyond value and they have helped me as a sounding board and unlocking further fields of expertise which ave been so valuable. The contributions and discussions with my oldest friend John Andrew on geology and the rocks of Townhill and Kilvey have been particularly inspiring. John passed away in August 2024 and I miss his help and support terribly.

The cover of Cilfái was part of a painting of White Rock I did a while ago, mainly to show the extent of the Cae Morfa Carw waste tip (the orange land). The Tawe is on the right, and the original long workhouse of White Rock is at the top.


I must also thank the staff and colleagues at Coed Cadw/Woodland Trust who, unwittingly perhaps, spurred me on to re-explore Kilvey some thirty years after I last surveyed the land in the late 1980s. All the modern mapping was completed using the open-source QGIS application which has become a central tool as a landscape historian over the past ten years. Finally, I must mention the help and support of Kilvey Woodland Volunteers. Without the passion and commitment of the volunteer body over many years, I doubt that Kilvey would be the special place it has become. As I write this, Kilvey is under more threats from the local council and developers, and I hope this little book records a few milestones in the ongoing Kilvey story rather than an ending.


The first edition of Cilfái was remarkably successful. The aim was to fill a gap in knowledge about the Hill in the constant challenge to take care of it in the face of threats of irreversible destruction from tourist developments and an uncaring local authority. There are now many more local environmental and residents groups aware of the current value of the land and the potential loss Swansea faces if the destruction begins. This book was the first of the Cilfái trilogy, the second book covered Woodland Management and Climate Change, and the third book covered the heritage features on the hill. This book was rushed into print to address claims from the Local Authority that there was ‘not much up there’. Since 2023, I’ve taken hundreds of people on walks to view the biodiversity, history, and heritage of Cilfái, and I’ve packed out numerous community centres and halls to talk about the history. Hundreds of people have been converted to the value of the landscape we may lose.

My books: latest…

I’ve now got a stock of my latest book Y Tân.

Y Tân: A History of Destruction, Swansea 1941 is about my history of the Three Nights Blitz in February 1941. The town suffered appalling damage, and many argue it has never recovered. My grandfather died fighting the fires on the last night of the Blitz in Castle Street which was the site of a number of tragedies on that dreadful Friday.

In Y Tân I examine the situation in Swansea in the month before the attacks and look at the vulnerability of Swansea to German bombs and incendiaries. I examine the history of the weapon that destroyed the town and explain why Ben Evans was so vulnerable to fire. I examine the history of Castle Gardens and the reasons it became so dangerous. I also reconstruct the events of the three nights with eyewitness testimony from local people, war diaries and German air force sources. A chapter explains what happened to the piles of rubble in the town that eventually gave way to the redevelopments we see today—copiously illustrated with photos, maps and archive records from the author’s collections. Fully academically referenced.

Y Tân complements the groundbreaking examination of Luftwaffe intelligence maps and plans published earlier this year, Eye of the Eagle: Luftwaffe Intelligence and the South Wales Ports 1939-1941.

Y Tân is £16.99, easily available from the author, or you can buy it online here.

Penllergare: The Ancient Trees

The latest press release from Welsh Government about the National Forest for Wales confirmed that Swansea’s Penllergare Valley Woods has been confirmed as a National Forest site. I think this makes it one of the hundred announced sites so far.

It is a clever bit of policy from Welsh Labour and throws a bit of recognition and identity branding the way of some struggling woodland sites. Creating a Welsh ‘network’, however fragmented, can only be a good idea.

The pre-medieval road to Nyddfwch in the Penllergare Valley Woods in 2018.

The name of Penllergare is as confusing as its location. It is probably an anglicisation of nearby Penllergaer. The lottery-funded restoration project adopted the name from the long-gone mansion owned by the Llewelyn family. The awkward anglicisation always makes me uncomfortable and I tend to refer to the area as the Llan Valley or Nyddfwch which were earlier locality names and are far more in keeping with modern sensibilities.

Above: The Penllergare woodlands are a complex mix of ancient woodland, garden planting, invasive non-natives and coal mining archaeology. An incredibly rich mix of history and environmment.

The valley woodlands thoroughly deserve inclusion in the National Forest list. I spent nearly ten wonderful years surveying and researching the landscape and woodlands until I felt compelled to leave in the face of the ugly politics and personalities that run the charity. Some of the staff and volunteers I worked with were some of the finest people I ever experienced in conservation circles, although all have been hounded out by the organisation, which is such a shame.

The original mission of the lottery-funded project was to recreate the nineteenth-century estate gardens of the Llewelyn family. It was centred on making something of the remaining walled garden and the paths and planting of the Llewelyns, a wonderful collection of exotic trees, native (1800s) planting, and a collection of Rhododendrons. The premise was ambitious in the early 2000s, and many of us were surprised that it got funding, as we knew the concept was challenging because of climate change and the lack of surviving substantive features. I think the charity running the place is now pressing for more money to keep the place going. Some of you who came to my Environment Centre lectures may remember I compared the limited effectiveness of money invested in Penllergare with the far better return on investment of money spent on Cilfái.

Above: The Nyddfwch Oak in Penllergare.

The wider area of woodland contains significant ancient trees, 1950s Forestry Commission planting and a spectacular collection of unusual and exotic tree species (the remnants of the nineteenth-century garden). Much is made of the links to the Llewelyn family, although they abandoned the site for a nicer house elsewhere. I imagine the family’s estate managers will be unhappy at this latest National Forest status as they were hell-bent on selling for housing; the land is on a short lease for the charity.

Above: Ancient tree stumps from the Penllergare valley. The area was cleared for timber in the 1940s although many trees and ther carcasses survive providing an excellent reservoir of dead wood. At one time the management wanted to sell the wood for firewood LOL.

The history of the nineteenth century is only of limited significance. Far more interesting is the history of the valley in the early 1700s, when it was devastated by coal mining. So, the land is a good example of early Welsh industrialisation and the recovery after that, when the coal was worked out in the 1790s. The ancient trees are an incredible survival from the coal mining devastation of the 1700s and were probably rejected for harvesting as timber because of their shape. I prepared a draft book on the woodlands a few years ago, and now may be the time to turn it into a real entity.

I used to take many groups into the woods to explore the woodland, let me know if you’re interested and I’ll put together a walk.

Above: My original manuscript. Maybe I’ll make it real.

Cilfái: The Importance of our History.

Who owns history?

Last Saturday, I talked about the history of Cilfái as part of our National Local History Month celebrations.

I had a packed room in the Central Library, not to see me… but to listen to the topic. Concern over losing our history and heritage is mounting as more threats from local Council plans get closer. I knew many of the audience, some of my old colleagues, heritage and environmental workers, and my past history teachers. There were a lot of local people as well who made an effort to come and sit in a warm teaching room on one of the hottest days of the year.

The combined years of experience in the room were amazing. People who had worked on the hill researched and cared for it, and a newer generation is taking on the challenge of future care. There was an unbroken chain of partnerships and friendships dating back to the pioneer historians Clarence Seyler and George Grant Francis.

The talk and the questions session afterwards led me to reflect on the history I was talking about. Much of the past fifty years of Cilfái history is not documented and runs a significant risk of being ‘reinterpreted’ by an unmindful local authority and a foreign tourism company. That risk of deliberate amnesia was one of the reasons I wrote the Cilfái volumes.

But who ‘owns’ the history? It is always an important question. In 1891, Oscar Wilde penned an often-quoted phrase, ‘The one duty we owe to history is to re-write it.’ Although Wilde was likely thinking more of fine art criticism, the statement holds up in modern times with the revision of colonialism and racism prominently featured in research and popular histories. I’m part of that process as I talk of the environmental pollution and ecocide that accompanied the explosion of industrialisation and exploitation in the Swansea Valley.

As good as the Wilde observation is, I felt I was always led by this statement from George Santayana in 1905…’ Those who cannot remember the past are condemned to repeat it.’ I suppose the ‘remembering’ or ‘forgetting’ can be both wilful and accidental. In the past month, I have had conversations with senior Council officers over Cilfái, where officials were adamant that records and land titles were entirely in order concerning the hill (and officially stating that was the case) whilst not checking anything about the truth and validity of those statements. The main reason behind their indolence was an intention to wilfully ignore the hill’s history. After my pushback, the senior planning officer had to retract those silly statements. The worst part of the episode was the inherent untruths and misrepresentation of vague facts advanced by Council employees who may be qualified but are rarely experienced. The injured parties are us as the public.

In books and talks about the history of Cilfái, I have tried to open ownership of our history to the broader public to combat the apparent desire of some to shut down debate, consultation, and knowledge. It is also important to remember that some of the most vocal Facebook warriors in unquestioning support for foreign tourism company plans have never been on the hill.

Ecological Monitoring: My complete protocol

This is my protocol from my civil service days. I used this (in whole or part) to educate, plan, or review monitoring programmes. Monitoring is hard to plan and very hard to do. In the UK, funding is often rewarded for a ‘project’ but the concept of understanding whole life costs is rarely appreciated. The money wasted on community lottery funding schemes is heartbreaking as projects are devised, money spent, and then there is no conception of maintenance or longer-term costs. Locally, I know of over £3m in lottery funding that has been wasted in ill conceived schemes with no oversight and unqualified charities signing cheques with no regard for quality or care.

As a Gateway Reviewer I was often brought in too late in a failing scheme, and my role then was merely to record the errors and failures. If we had been brought in at strategic planning or business case, it was better.

This plan was my basic script for programme oversight and I found I could frequently reverse engineer it to interpret what had gone wrong or explain how a programme failed.

I experienced three types of monitoring:

  1. Curiosity or passive monitoring. As I often undertake on Cilfái, and became the output in Cilfái: Woodland Management and Climate Change.
  2. Mandated monitoring. Imposing a requirement on a programme as part of their funding and appraisal system.
  3. Question-driven monitoring. The dreaded ‘research question’ approach of many academic bodies, often a waste of talent and time and merely to get a tick in a box. This is the stuff that is funded, completed, and locked away for ever. The best use of resources is through good quality research questions. However, I used to read questions that were long and incomprehensible…so how do you answer them…or better yet learn from them?

As a reviewer for government, I saw monitoring programmes that were ineffective or failed completely. It doesn’t help that many in the biodiversity sector see monitoring as a ‘management activity’ which is unrelated to scientific research.

The failures I saw

  1. Short-term funding preventing planning. Question-driven monitoring pushed staff to plan backwards…data first, question later. Also, data management was often dreadful with no structure or futureproofing for reviewers. A monitoring timescale can be a decade…who stays around for ten years on a program in biodiversity? Nobody…which makes succession planning vital, but never done. Loss of key personnel and the corporate amnesia that follows was harmful for staff and quality, but often treasured by politicians and managers who want a predecessor to own mistakes.
  2. The Shopping List approach. An impossibly long list of monitoring topics instead of a sharp defined monitoring objective. It is backlog planning in programme speak.
  3. Failure to agree on what to monitor. Often politicians and managers want career-enhancing metrics…not realities.
  4. Flawed assumptions. A very human desire to compare one set of data to something elso or associate with something else that looks good, but has incompatible data. The temptation to ‘salt’ data on key metrics (e.g. bats, reptiles, invasive speciers) was overpowering. An overclaim is more likely to get published etc.

It is a big graphic, so you may need to enlarge it.

Cilfái: The Principles of Diversity and Resilience

Cilfái’s connectivity to other wildlife and natural habitats is not just a concern, it’s a massive issue. The dangerous main roads dominate the wider extent, west towards the river and north towards what was the Enterprise Zone. Within the woodlands, further development for bike paths, walking trails and cable car routes are all immediate risks for ruinous fragmentation. The width of paths and firebreaks and cableways and how we manage the woodland edge habitats are crucial. Cilfái’s wider nature network must be urgently mapped and managed using the ten well-known best practice principles (Crick and others 2020a: 91–101).

1. Understand the Place. Understanding the community and the natural networks that are in place.

2. Create a Vision. Create a future that is understandable and engages the biggest stakeholders, usually the local communities, animals and plants, and those responsible for caring for and maintaining the land.

 3. Involve People. Communication, engagement and consultation are tremendously important. Do we see that commitment from local politicians?

4. Create Core Sites. The central Cilfái woodland is our core site.

5. Build Resilience. This is protection against climate change-related events such as drought, torrential rain, wildfires, and temperature extremes. I describe some of these in the book.

6. Embrace Dynamism. Nature changes constantly. Change can happen in a matter of minutes: a tree blows down, a stream bursts its banks, or a rockfall changes the shape of the land. We can’t keep spending money on keeping things ‘as they are’. Is expensively recreating a nineteenth-century landscape that relies on money, gardening, water and stable weather and climate  (as they do at Penllergare Country Park) even possible in the modern world? We must accept and adapt to our situation, not the situation we would like to be in.

7. Encourage Diversity. There is genetic variabilityspecies diversityecosystem diversity and phylogenetic diversity. Diversity is not distributed evenly on Cilfái. The ecosystem we see building on the hill results from 50 years of growth and change.It should be allowed to develop naturally. The notion that a local Council or a private tourism company can care for the land is an outrageous conceit.

8. Think ‘Networks!’ Plants, animals, and people move and live in connected networks.

9. Start Now, but Plan Long-term. Short-term is about 3 years, long-term is about 50 or more. Nobody knows what the world will be like in 50 years.

10. Monitor Progress. We can’t understand change if we don’t observe it constantly. A 3-day ecological survey by a non-local contract ecology firm on behalf of a foreign tourist company doesn’t cut it.

However, there will always be uncertainty about what Cilfái can contain because it is always prone to extreme disturbance.

Crick, H.Q.P., I.E. Crosher, C.P. Mainstone, S.D. Taylor, A Wharton, and others. 2020. Nature Networks: A Summary for Practitioners (York: Natural England)

Above: The western part of the woodland with areas of particular attraction to birds and wildlife highlighted in shades of Brown. These areas are open or semi open and also show strong characteristics of ‘woodland edge’ or ‘Stand A’ structures (see Annex 7). These areas have their origin in polluted soils from slag tips or fire damage from wildfire attacks. The old coal adits and leats provide damper cover than the surrounding woodland and frequently act as biodiversity hotspots because they retain moisture in drought conditions. These Brown areas are the current centres of natural regeneration. The woodland cover in these areas will not be necessarily native species, it is far more likely to be the ‘Cilfái mix’ of coniferous, native and invasive non-native. These areas are rapidly becoming reptile hotspots and also very strong presences of foraging bats.
 

Woodland Resilience

I talk about ‘Resilience’ in Chapter Three of the second Cilfái volume.

The term ‘resilience’has become a key concept in our landscape management. Resilience in woodland is becoming a broader and more important topic as climate change starts to bite.

In its current form, Cilfái is resilient. Yes, people burn it every year, but that results in more biodiversity hotspots as the burnt patches grow back with local species of trees and vegetation that are much more resilient to fire and drought.

Anything done to the woodland should be to enhance resilience…not knock it back with imported plants, plastic tree tubes and high maintenance planting schemes.

Diversity in the Cilfái woodlands can range froim genes and species to habitats and landscapes. The complexity of the Cilfái woodlands ecosystem will always be limited compared to a woodland that is older or has not been polluted. Still, the pollution history of the hill makes the ecosystem special and probably even unique.

Above: The seaward slopes of Cilfái are increasingly susceptible to windstorms which easily topple the trees that often have poor anchorage because of the soil conditions. The resulting deadwood (both prone and standing) provides useful food and shelter for many animals and insects. The natural regeneration quickly takes over a windblown space and colonises fast with the ‘Cilfái mix’ of local species. Incredibly, this site on the proposed tourism development is a bat hotspot. (Author’s collection).

Cilfái: The importance of dead wood.

As Climate Change accelerates, the conifers are increasingly susceptible to higher windspeeds and many trees will snap forming ‘snags’ such as this one near the Steam Engine Spring.

Snags allow insects, birds, and bats into holes and crevices in the dying wood providing much needed habitat. Where it is safe to do so, features like this must be maintained.

Dead wood is a vital part of biodiversity and a recovering ecosystem. Wherever possible, we don’t ‘tidy it up’ or sell it for firewood as the Penllergare Trust used to do.

Dead wood is part of life.
