There’s nothing glossy about the book which boasts not a single illustration, not even a map. Going against the adage of pictures painting thousands of words Jim Perrin says you can convey so much more in writing; mixes of description, history, hopes, fears and so on. The writer can direct the reader more specifically, creating a mental picture, forcing thought and contemplation as opposed to a quick flick through.
That sounded plausible but I also liked what the publisher (Dylan Williams of Gomer) said at the book launch. Not only was Jim’s manuscript seven years late it was more than double the target wordcount. In parallel with the words, photos by Ray Wood had been commissioned and delivered but, with 65,000 words that were too good to be cut, there simply wasn’t the room for them.
It’s a very learned book, with many of those words being quotations from older texts or footnotes, and a ‘select bibliography’ stretching to seven pages, but it’s also very personal. Even the man who drove his Vauxhall Frontera to the summit (twice) gets a mention. This is followed by an admission of the author’s ‘hoodlum’ motorbike rides to reach the best climbing cliffs in time for an after work climb .... ‘It ill becomes old men like me, whose pasts will scarcely bear the weight of scrutiny, to grow sanctimonious’.
Excellent article by Kelvin Jones of BTO Cymru in the latest edition of Natur Cymru. This can also be read online (for free!) on the Natur Cymru website. The title in the magazine 'Birdwatching on Wales’ Coastal Path' is a bit misleading, covering just a small chunk of the path, as Kelvin explains in the final paragraph ....
‘I started writing this short piece as a description of an ornithological journey along the Wales Coast Path. But in this brief article we have only succeeded in travelling from the River Dee to Puffin Island. The remainder of our journey – around the coast of Anglesey and the Llŷn Peninsula and down to Porthmadog and St. David's, and then over to the magnificent Severn Estuary - will have to wait for the time being. Nevertheless, I hope that I have succeeded in giving you a taste of the orthnithological feast you can enjoy in North Wales.’
That was the summer I started my wine making: bilberry, blackberry, strawberry, hawthornberry .... I gave them all a go and with mixed results. I expected bilberry to be my favourite, the Rolls Royce of wild berries, but sixteen months on and it’s still got a fizz to it. Damson was the best of the bunch.
When I explained to Sue that I was going to give some wine to our neighbours for Christmas she asked what did it taste like? Her verdict was cough medicine but I felt sherry was kinder. So that’s what went on the labels ‘Dduallt Damson Sherry 2011’.
Our neighbouring farmer consumed his bottle that first night and has declared it a fine potion needing but two paracetamols. That’s good enough encouragement for me to try again next summer. Let’s hope for a better growing season.

There are some websites I try to look at every day. One that is always worth reading is Mark Avery’s blog ‘Standing up for Nature’. A former Director of Conservation with the RSPB, his articles are written with passion and humour, so I was curious to see if he could sustain his usual quality over 300 pages or more.
The tone is set by the title. This isn’t ‘Managing for Birds’ or ‘Caring for Birds’ or ‘Working-in-Partnership-with-Stakeholders-for-Birds’, although Avery does plenty of all three. It’s ‘Fighting for Birds’. It’s ‘in yer face’ nature conservation. It’s assertive, uncompromising and outspoken. Few prisoners are taken.
It starts slowly with chapters describing Avery’s youth, and his entry into the RSPB. I warmed to this, if only because his memories of ‘Peterson, Mountford and Hollom’, ‘The Selfish Gene’ and ‘Bohemian Rhapsody’ are mine also. There are chapters on early experiences in the Flow Country and working with roseate terns. You could be forgiven for thinking this is one of those rather worthy ‘my life with birds’ books.
But it gathers pace with a chapter on the vital importance of sound data for bird conservation, before moving on to nature reserves, climate science, farmland birds and the value of reintroductions. Avery provokes the reader at every turn. Was it right to shoot ruddy ducks? How would a reintroduced white-tailed eagle fare in Norfolk? What was Prince Harry really up to, that evening when two hen harriers were shot at Sandringham? Do egg collectors suffer from sexual inadequacy? There’s a lot to ponder.
But despite the combative tone, it’s Avery’s candour that makes him so persuasive. Nobody in nature conservation really thought hen harriers could affect grouse populations. But Avery readily acknowledges that the science is undeniable; they do. As a Labour Party member, he praises Michael Meacher, but also has warm words for John Gummer. The RSPB’s experiment with farming has been a qualified success, but far from plain sailing. At every turn he emphasises being honest with ourselves. In an age when, from climate change to badgers, opinion drives evidence rather than vice versa, this attitude is so refreshing it could make you cry.
It would be hard to make any criticism, but the reintroduction chapter makes no mention of the osprey project 20 miles from Avery’s home which, incidentally, led to the species breeding again in Wales. The section on politics is also a bit thin. It’s so much more complicated than a simple left / right question. What of differing shades, from one-nation Tory to neoliberal Thatcherite? What of the Liberal Democrats, UKIP, the Greens, Plaid Cymru, the SNP, and Northern Ireland parties? Maybe that is another book.
After a delightful ‘light relief’ chapter of anecdotes (my favourite: the opening ‘Unleash Hell!’ scene from the film Gladiator was filmed next to the RSPB reserve at Farnham Heath) the book comes to its conclusion on the future. Whether you agree with Avery’s views on a ‘super NGO’ or not, it’s inspiring stuff. His message, that you don’t have to be a victim, that if we choose to be passive then we collude in the environment’s degradation, is compelling.
If you are a young person, maybe starting out on a career in nature conservation, ‘Fighting for Birds’ should be in your induction pack. No one, perhaps except Peter Marren, writes better. But anyone who cares about the future of wildlife in Britain should read this book. And if you enjoy it – and I bet you will – there’s more at markavery.info/blog

|Is this Tremella Mesenterica - Witches' Butter?|
I'm just getting the hang of this wonderful gadget. Taking the photo was easy enough. Re-sizing and uploading it to this blog with a few words was also pretty easy with my precise location recorded by the built in GPS. On the other hand, making and receiving phone calls without cutting people off - I've yet to master that, Rome wasn't built in a day.
I'm optimistic it's going to be a powerful tool for nature. BTO's BirdTrack app is brilliant. Type in the first couple of letters of what you've seen and select the full name from the drop down list. The default location is where you are standing. Add in the number of birds seen and your record is automatically sent into BTO. By making it so easy, will there be an increase in the number of recorders and records?
What about the quality of the records? 3 of my 5 records have a comment saying 'Not yet checked against BirdTrack thresholds'. Presumably this is some form of validation? Is there an individual checking my entries or is it just a test of reasonableness against previous sightings for this area and time of year? My record of a lesser spotted woodpecker has been declared valid. This is one I didn't see but having heard its call I clicked through a long list of bird calls (an app of course) until I finally found a close match.
PlantTracker is another app that I've downloaded (for free) and looks an easy way to identify, record and map the presence of invasive species. Leaf Watch is an app with the specific purpose of tracking the spread of the miner moth and its impact on conker trees. Do you have any other apps you'd recommend I take a look at? I'm sure there will be a raft of new ones to herald in the spring.

I’m biased: I like Falcon, I’ve had the pleasure of meeting him in his home, of witnessing his uncluttered way of life and hearing him describe his hopes and disappointments. I also live next to Blaenau Ffestiniog, so any comments about his book (written by Peter Wakelin) are not wholly objective.
The book contains 200 of Falcon’s drawings, now in the hands of public bodies for posterity, and the bulk of them record the industrial heritage of Blaenau Ffestiniog, Falcon’s home for over forty years.
In the course of the book I learnt a lot about his life: how he got the impressive name of Falcon; how he came to move from Grimsby to Coventry, to London and eventually to Blaenau Ffestiniog; his bold decision to give up job security to follow his calling. I loved the drawing he sent to his mother depicting the layout of his bedsit in Putney during the times when he designed, amongst other things, first class bars and cabins for cruise liners.
Within the book there are many favourite drawings for me including the series depicting Tŷ Uncorn, the one chimney house with four tiny cottages sharing a central chimney. Was this a pioneering attempt at central heating? I like knowing what it looks like inside as I walk past it near the police station.
The final chapter is written by Falcon and titled ‘My Working Process’. On the last page he talks about the drawings made in other industrial towns in which the buildings have long since been demolished or renovated. ....’After half a century of recording, I believe that Blaenau Ffestiniog and its landscape are the best and most complete surviving industrial landscape in Britain’ .... ‘I feel we should save one example of a nineteenth-century industrial town as a complete cultural and historic entity. So my final message is: if you like my pictures, then please take care of the subject that inspired them.’
And so we should. As for the book, which has been published by The Royal Commission on Ancient and Historical Monuments of Wales, not only do I recommend it, I suggest you get three copies. One for cutting out and framing images on left hand pages, another for the right hand pages and the third for a good read.

The Birds of Meirionnydd has just been published by the Cambrian Ornithological Society. Its author, Rhion Pritchard, has made a really good job of writing up the current status of each species recorded in the county. The book is an A5 softback, similar format to the Cambrian Bird Report, with 210 pages plus 8 pages of habitat photos.
The previous county avifauna by Peter Hope Jones was published in 1974 so an update is really needed, especially as much more information is now available on the commoner species because of surveys carried out since then. Many species have a much changed status, the Red Kite for example. In 1974 Hope Jones wrote ‘... a pair or two have bred on several occasions in Merioneth’ whereas now ‘Fieldwork for the 2008-12 breeding Atlas recorded this species ....in 117 tetrads* out of 463, making this the second most widely recorded raptor in the county after the Buzzard’. The Hobby has appeared as a breeding species, but Kestrels and Merlins have declined. Let’s hope this book will stimulate more field trips to track down the more elusive species, such as Nightjar and Long-eared Owl.
* a tetrad is a 2x2km square, a recording unit used for distribution studies such as bird atlases.

Blaenau slate took 450 million years to form and quarrymen took 150 years to rearrange the mountains. In just twelve months the town has been transformed and reconnected with its heritage with slate sculptures constructed by Howard Bowcott.
First Minister Carwyn Jones will visit today, with the sun shining and work complete. But if you’d like to know how it was done, the film below shows how the sculptures were made.

There was a warm atmosphere at yesterday’s Moelyci festive fair and an extra marquee was erected to accommodate the many stalls. Kurmang from the Model Bakery in Blaenau Ffestiniog was there with his Kurdish pasties. I didn’t feel strong enough for one of those so had a spinach and feta pastie for breakfast and a cheese and onion one for lunch. When asked what time he’d got up to do his baking he replied midnight! It was good to see he had sold out by 3pm.
I was on the Natur Cymru stall and met lots of existing subscribers who did an excellent job of directing new recruits in my direction. By the end of the day there were ten new subscribers. With subscriptions you can never say you’ve sold out but ten made me very happy. The stallholders either side of me were getting a bit cheesed off with the spiel .... ‘a subscription to Natur Cymru is not just a gift for Christmas’.
As you may know Moelyci is in a difficult financial position and appealing for support. Visit their website to find out more about the wonderful work they do. Below is a message from John Harold and two attentive elves!

A great selection of walks makes it into the top ten. Portmeirion combines fantasy and escapism with a walk across the Cob, perfect for steam trains and what must be the ultimate view of Snowdon. A mile south at Ynys is the start of the next walk, down the estuary and back through the churchyard, with the grave of Richard Hughes of High Wind in Jamaica fame. (If you want a bit more background on this area there is an article titled Aberdwyryd.)
In between those two walks is of course Maentwrog-on-Sea which for the time being is an honorary coast path resort; being the lowest point at which you can officially cross the Dwyryd until the new Pont Briwet is built.
The tenth walk is down my memory lane from Borth halfway to Aberystwyth. In 1960 I think ours was one of only two caravans in the village and the sun shone all through the summer. In subsequent student days the walk along the coast was a popular Saturday evening prelude to sampling Borth’s pubs before catching the last bus back to Aberystwyth.
At £4.99 it’s excellent value .... that’s less than 50p a walk!

My council issues blue boxes for recycling with instructions to keep things separate. Glass bottles and jars are sorted into different colours and need to be kept apart from cans, plastic bottles and paper products. Finding suitable objects (other than carrier bags) to sub-divide the boxes is a constant challenge. I do this task every weekend, about the same time I used to go to evensong and it feels a bit confessional. Did we really consume that many green bottles?
Other councils are more laid back and say chuck all the non-glass into the same box. Presumably this means the residents are likely to recycle more waste and the council’s collection and onward handling is that much simpler. But surely it creates a big headache downstream?
|UPM Shotton and the MRRF|
Not at UPM Shotton where they have a massive recycling centre which handles the waste from 30% of UK households. Huge lorries are constantly arriving from across the UK and as far afield as Scotland to deliver all sorts of materials including the jumbled up boxes of ‘co-mingled’ stuff to use the recycling jargon.
I watched a truck disgorge its load of 25 tonnes by means of a ‘walking floor trailer’. This gets loaded onto a conveyor belt for a human check to pull out things, such as a duvet, that might snag the machinery. Thereafter it’s all done by machine with a bit of human quality assurance at the end. Powerful magnets and eddy current separators extract the metals. Sensors detect the characteristics of, for example, carrier bags and jets of air blast them on to another conveyor. And so it goes on until bales of sorted materials are stacked up ready to load onto trucks for factories to use again.
But not the newsprint. Each year Shotton converts 650,000 tonnes of old newspapers into half a million tonnes of recycled newsprint. The most modern of the three paper mills, the largest in the world, produces paper nine metres wide at 60 mph!
I was pleased with what I saw and all the efforts to power the plant with renewables – even the unwanted newspaper ink gets burnt to generate power. Driving back over the Denbigh Moors my head was buzzing with what I’d seen, the deafening noises of machinery, the putrid smell of rotting biomass. Ahead of me the northern Snowdonia range covered in snow and an array of wind turbines poking over the horizon like giants practising their semaphore.
It was all very impressive but things would be so much better if we consumed less products and packaging and reduced our need for recycling.
Abergwesyn Commons, owned by the National Trust, are about as close to a wilderness as you get in
For the last two years Project Officer Jess
Tyler has been working on management of the area, and wonders if we are
taking the uplands for granted. [This article appeared in Natur Cymru Autumn 2011] Wales
The idea of Common Land comes from the time of William the Conqueror, and the Commons Registration Act was introduced in 1965. Sheep walks of the commons were officially registered as Common Land Blocks. It is known from records over the last 1,000 years that Abergwesyn Commons have been predominantly a sheep grazing area. The Cistercian Monks, based in Strata Florida, were renowned for their wool production and for centuries during the medieval period they owned
and more. At one point in
history the king granted a royal decree stating the monks did not have to pay
tax on the wool they sold. Deeds dating back two or three hundred years show
ownership of up to 3,000 sheep on a single farm. Abergwesyn Commons
There is no place I have been quite like this part of north Breconshire, the rooftop of
Lichen-covered Birmingham Corporation watershed markers indicate the 11 mile
boundary between the Wales Elan Valley to the north and
to the south. The medieval remains of long huts, summer farm dwellings, remind
us how this region would have once had so many more communities relying on a
land less isolated than today. The tracks of the drovers and evidence of peat
cutting reflect the activities of times gone by. Prehistoric sites scattered
across the area show signs of activity from the Bronze Age and before. The
quartz standing stone on the hill top of Drum Nantygorlan would have been at
least 2 metres tall when upright. Now it rests on its side, pointing walkers to
the isolation beyond. Abergwesyn Commons
Abergwesyn Commons consists of seven contiguous upland commons, and are a prime example of land affected by many external influences. For the last two years colleague Joe Daggett and I have been looking at management of the area through the Abergwesyn Commons Project. We have also worked extensively on the large areas of blanket bog that exist on the commons, carrying out restoration works.
On the westernmost Common there are large gullies that drain from an area of 5-6 acres of bare peat – at worst these are 2.5 metres deep and are down to the mineral soil. Areas of bare peat are not necessarily a bad thing. Small areas of only a few square metres seem to have shifting colonies of cotton grass; bare areas get covered up and covered areas become bare. The golden plover has adapted to using these areas and it looks very much like a natural process of this relatively liquid, unstable peatland. However, the creation of larger areas of bare peat appears to be a culmination of factors caused by people rather than being part of a natural process.
Thousands of acres of the west side of Abergwesyn Commons are dominated by purple moor grass, Molinia caerulea, creating a huge fire hazard from the litter it leaves every year when it dies back. When fire takes a hold here, square kilometres of vegetation are burnt. Ash from the burn further encourages the Molinia, which progressively overwhelms other bog species and aids the drying of the peat. Often these fires are superficial and only the tops of the plants are lost, but if the fire gets into the peat it can burn for weeks, even months. The damage this does to the habitat is significant.
It is likely that fire damage contributed to the creation of this larger area of bare peat but, however it started, it is clear that the area is increasing in size. We decided to target one area owned by the Trust, and a series of terraces/small dams was created to slow the water flowing away from the area, catching the peat before it got washed away. Materials local to the site were used, such as peat from hags, and chunks of bare peat that had fallen from undercut banks and from lone, small hags that had been isolated through erosion. The vegetation from on top of these hags has been used to help bind the dams and stabilise them. So far these terraces seemed to have worked well.
Mowing the Molinia
Under the fire management part of the project, 40 hectares of Molinia were cut last year to reduce flammable material. Whilst these cut areas would not stop a fire, we hoped – and it was subsequently shown – that in reducing the fuel load for a fire, it would not burn so intensely. National Trust staff and some hard core volunteers filled 1,000 heli bags with 250 tons of Molinia, which were transported and spread across the bare peat to protect it from the elements and create a more stable environment for vegetation to grow. It is likely that some Molinia will grow on the mulch but, as seen through small experiments carried out elsewhere, cotton grass and bilberry should also grow. So far the work seems to be proving highly successful.
Changes to grazing
As much as the Trust would like to carry on cutting Molinia on the commons, it is not financially sustainable. This is where grazing comes in: in the long term the right grazing will be the answer to controlling Molinia. Although the National Trust owns the Commons and may have 'owner privileges', it does not have any grazing rights, therefore cannot manage the grazing of the land directly. This job, rightly so, falls to the farmers who own or rent the grazing rights and who are often best placed and equipped to farm these hills.
Other evidence shows there have been varying numbers of cattle, ponies and sheep on the Commons over the last thousand years, with cattle outnumbering sheep at one point but today numbers have dramatically declined. Pony numbers have decreased, from several herds of up to 50 ponies each, to barely a handful of herds of fewer than ten ponies. Currently there is no value in hill ponies; they are no longer sold for meat, which was their main worth, so it is understandable that farmers do not keep so many.
In the last century cattle numbers have dwindled to almost nothing. There is a lot of work involved to get cattle to stick to a heft, as, if they do not, there is over 100,000 acres of open access land for them to explore. Hefts are lost and, as was shown after the foot and mouth epidemic ten years ago, once lost, hefts are difficult to get back. There are also the complications and worries of TB and other diseases spreading across herds that have no fences between them, not to mention the in-by land they will need in the winter. The financial viability of small, slow maturing cattle herds on the hill is also an important factor. As well as the loss of headage payments, changes in farming practices, farms lost to forestry, and farmers giving up farming for one reason or another, have all contributed to the decline. The list of obstacles goes on.
This decline in mixed grazing, with plummeting numbers of sheep, has helped Molinia to become a dominant plant species. Yet there still seems a policy to reduce sheep numbers without enabling or supporting the increase of ponies and cattle. The number of birds recorded, such as golden plover, red grouse and curlew, has decreased over the same period that grazing patterns have changed and the numbers of livestock on the hill have fallen. Surely there is a link here?
A way forward
This is where the whole picture needs to be looked at. As part of the blanket bog restoration, 12 Welsh Blacks have been introduced on the most westerly common, working in conjunction with a grazier. A dozen cattle are not going to solve all the problems, but are giving us a good idea of the reality of having cows on the hill and how we can overcome any obstacles.
The importance of blanket bog is recognised globally for the role it plays as a carbon store. The reality is, the resources we need to turn around, long term, the decline of this habitat, are not readily available. With any resources that do exist, we must make joint decisions with the farmers to ensure we get best value and that the work done is likely to continue. For Abergwesyn Commons to become a viable farming and conservation area, we must support the graziers to graze for the habitat we want. We may be surprised to find that what is wanted, in terms of habitat, and what the farmers would like to see, may be one and the same thing.
We hold these uplands so dear to our heart yet there is so little actual support for them. This begs the question: Do we really fully comprehend the value of supporting these upland areas to breathe and adapt for the future, whatever that may bring? Or will we continue to take the uplands for granted?
In the life of this landscape we are just a blink of an eye. However, this does not lessen our responsibility towards it. Perhaps we need to listen to and support the families that have been its keepers, who have taken care of these hills for centuries, so that they will want to continue taking care of these sleeping giants for the centuries to come.
