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 variability, species diversity, ecosystem 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.

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.
 

Saving the Environment: The importance of Information

When I worked for the Government, I did some tours of duty in environmental activities. Over the years, I monitored programmes on the health of Honeybees, parks protection in Greenwich’s ancient woodlands, Restoration of the environment in the Olympic site in East London, and several small conservation programmes on security sites for the MOD, where fencing things off from the general public did wonders for the local biodiversity. In all of that, I learned that data and information are vital. Far too often I heard the comment ‘there’s nothing there!’, often from gentlemen in their fifties whose only interest in nature was how to kill it or cut it down. When I got to a position of some influence, I could slow down or even reverse developments by insisting on a good quality ecological survey before any construction work. Sometimes, this was deeply unpopular as the construction industry usually has little interest in conservation or environmental care…what we see of due diligence by building firms is there because the Law forces them. This will definitely be an issue in Cilfái with the Skyline development. That tourist firm will promise anything in the planning permission stage but quietly ignore it in the building phase, knowing very well that Swansea Council does not have the resources to monitor and enforce anything. We as volunteers will need to monitor the destruction to try and ensure it is kept to the promised minimum. In December 2022, I prepared the first of a series of ecological protection documents based on my time in Whitehall. The key one is called an Ecological Constraints and Opportunities Plan (ECOP for short). I did one for Cilfái based on what we knew at the time. It proved quite popular and still is, judging from the large number of downloads it still gets from all over the country. Eventually, the ECOP evolved into the second book Cilfái: Woodland Management and Climate Change on Kilvey Hill, Swansea. I published all my survey notes and plans going back over about ten years of tree and animal survey, including all my work on the Hill. So, the book has an explanation of the data covering the Hill and lists of bats, birds, plants and animals I found or saw presence of. I also included the wonderful observations made by Carl Squires over many years of walking the Hill. I also added some of my Climate Change risk analysis from my time working for UK Parliament. Below: A mash-up of some of the Cilfái data from my surveys and explorations.  It is complex because ecology always is. The red dots are dead or dying trees, the dotted lines and light green stripes are areas for better bird habitat, Yellows and oranges are different types of open land, and darker greens are the Forestry Commission plantation trees. The red lines show the ghost of the coming area of Skyline destruction.
