Sweet Chestnut Coppice


Before I moved here to the Limousin, I had never really seen a Sweet Chestnut tree, in the far northern part of the Yorkshire Dales which used to be my home you just didn't see them. I new of only one tree on a nearby country estate which had only ever fruited once in the glorious summer of 1976. So seeing them here in their glorious profusion, reliably fruiting every year, for me really highlights the climatic benefits of living here in S.W. France compared to 700 miles further North.

In my locality it is like a weed, springing up everywhere, you cut it down and back it comes - twice as fast as before you cut it and that of course is one of the great qualities of this tree.
Looking at it's success today you would think that it's always been here - a native tree to this part of Western Europe but it's not. This came as something of a surprise to me and I thought that I new about trees! Infact it comes from Turkey and was planted thoughout Europe by the Romans who enjoyed the chestnuts and appreciated the versitility of this tree.

vigourous and prolific regrowth of up to
 2 meters in length at the end of it's first
season of regrowth
For myself, this ability that Sweet Chestnut has to reliablily keep regrowing each time it is cut down is sheer brilliance. Although it is widely known that many other tree species can be coppiced, few do so here with quite the same vigour and youthful enthusiasm of the sweet chestnut. I have honestly had regrowth exceeding 3 meters in the first summer after cutting, in a woodland situation this same regrowth is already starting to close up it's developing canopy after only 3 years. Compare this to a newly planted woodland, which could take perhaps 8-12 years to reach the same stage- depending on species and planting distance.
The length of each coppice cycle varies depending on what is the desired end product. Very generally speaking an established coppice is cut over on cycles of between 10 and 20 years, this will yield large amounts of wood for fence posts, poles for a varied range of uses, some firewood and a large quantity of brushwood which in the past would have been used for pea and bean sticks.

A selection of varying sized material that a short rotation
Sweet Chestnut coppice can yield.

Sweet Chestnut coppice managed on a 12 year cutting cycle. A
different block is cut each year so the supply of wood is almost
never ending. Note the regrowth sprouting on the recently cut
stools in the forground.
 Until recently this sort of material wood have been regarded as "waste" and left to decompose (which in my view makes it a long term soil improver and fertiliser and a valuable wildlife habitat for birds and insects and not waste at all). These branches can also be heaped around the cut stools to protect the tender regrowth from browsing by deer, which for me is a real problem.

As commercial pressures increase, many land owners are trying to squeeze every penny from their woods. The potential now exists to make this kind of "waste" brash into wood pellets for domestic or industrial heating. Follow the link to this site www.pellet-mill.de for home production pellet mills priced from only 2200 euros and are claimed to be capable of a production of 100-250 kilos/hour. According to the manufacturers you can also use materials like leaves,grass, paper and cardboard-including the junk mail-now that has to be the best use for it yet!

For me personally, I prefer a longer rotation of 35-45 years as I am wanting good quality logs to mill into planks with the remainder for firewood. Growing a coppice on a cycle of this time span means that thinning must be done periodically to reduce the density of tree stems. Thinning involves removing the stems that are badley shaped and/or overcrowded, this is to ensure that the growth is concentrated in the better quality trunks. Failure to do this will lead excessively long whippy trees with small crowns, the overall growth and wood yield of the coppice plantation will stagnate and a low value crop will result.

This is a parcel of my neighbours Sweet Chestnut coppice, totally unmanaged since
it was last felled over half a centuary ago. All the trees have narrow crowns so growth
 and wood increment has stagnated, the stems are long and spindly and only suitable
  for firewood and wood pulp- both very low values end uses.
 Here in the Limousin, Sweet Chestnut grows very well, you should start thinning this type of long rotation coppice at around 15 years old followed by a regular thinning every 3-5 years. The first thinning is the most labourious and time consuming as you are removing 35% to 50% of the tree stems, this can seem a little dramatic when you cut it- in some dense patches you get so many logs on the woodland floor there is barely anywhere to put your feet! However after the first summer the canopy is closing up again and you are left wondering if you should have thinned it just a little bit harder!

 This first thinning yields a great quantity of branches, and small roundwood and a lot of poles, I mostly cut these into 1 meter lengths for firewood but you could split them for fencing or try making rustic furniture with them.

This predomianly Sweet Chestnut woodland was felled 17 years ago and has been
totally unmanaged since. It is certainly ready for for the poorer and more overcrowded
stems to be removed-one of my tasks for this winter!






















The second and subsequent thinings are much quicker, easier and more productive as the stems are of a larger girth and you have already removed the poor quality ones. At this stage although your woodland is still technically a coppice, but to all intents and purposes like a well managed woodland.

A year ago this looked just like the previous photo. Now with all of the overcrowded
and worst shaped trunks removed it looks a lot more promising





















Thinning the coppice also has other benefits, the increase in light intensity reaching the woodland floor allows a herb layer to develop which makes it more interesting to insects and birds. The chestnut trees are also becoming mature enough to yield nuts which on these relatively young trees are less prolific but of a good size. Do not however delay picking them for long as the wildlife hoovers them up and stashes them away in no time, then the leaves fall and hide any leftovers.

 As each year pases, the final felling of the coppice approaches, this final act completes the growth cycle, to delay is not wise as decay will start to invade the base of many trunks. Sweet Chestnuts also have a tendancy to twist with age, you can see the spiral patten in the bark, splitting logs like this results in near corkscrew shaped splits that are a pain to stack and cut. Also the stools become top heavy and more likely to blow over in severe storms, as many of mine did here in the hurricane force winds of December 1999.

 Once they are felled you have not only a sizable amount of wood but the joy of watching the spectacular regrowth that flourishes from each cut stool and the accompanying surge in growth of the ground flora. This coppice cycle can repeat almost endlessly with the coppice stools slowly getting larger and more powerful over the course of many hundreds of years.


An example of very overmature coppiced Sweet
Chestnut. These have such a large canopy that they
are in danger of being blown down in high winds.
It is a dilema wether to keep them as they are for
their beauty or to fell them in stages to allow them
to successfully regenerate. 
One final thing to note that I have noticed, is when really huge Chestnut stools are felled they appear to have a greatly reduced ability to regenerate. These monsters usually have 3 or 4, sometimes 5 or more large trunks, each one perhaps between 30cm and 60cm in diameter, I have found that if you cut all these off in the same year often the stool will only produce a very few shoots or none at all. These isolated shoots are very vulnerable to deer damage and to being split off by gusts of wind, if this happens a huge coppice stool that may have had a lifespan of over four hundred years is lost and belive me it's a sad realisation when you realise that you have needlessly caused this because you were ignorant of the correct cutting techniques for these special ancient trees.

 By a process of trial and error I have found that if you cut down around half of the trunks one year, the stools regenerate really well,it is better to cut all the adjacent stems on one half of the stool. New vigorous regrowth will emerge from around the base of the cut trunks, you then let this grow for 2 or 3 years by which time it will probably be 2 to 3 meters in height. Only once this new growth is well established can you finally take down the remaining large trunks on the other side of the stool.

Here is an example of an ancient overmature Sweet Chestnut coppice stool, Last
winter I have removed the trunks positioned on the front side-which is the side that
is exposed to most light. New shoots have emerged from below where the trunks
were felled. As you can see the regrowth is not as prolific or vigorous as the photo
at the begining of this blogpost. I will leave it at least another year to fell the
remaining trunks. You can see a patch of decay on the trunk on the left, a strong
 indication that parts of this stool are close to collapse.

























By keeping some of the original trunks it keeps the sap being pulled up through the stool and maintains the ability of the new growth to resprout on the cut side. I suspect that as the stool ages it is less able to respond succesfully to the sudden shock that a felling of all the trunks must inflict upon it. So these really old trees need a more thoughtful approach to regenerate them, the problem is that if they are not cut, they blow over really easily, often lifting the entire root system out of the ground. Once this happens they are lost forever because the agricultural system that created them has long since dissappeared.

Considerations when planting a new woodland

As the former owner of a forest tree nursery I have been asked this many times, there are no definitive answers to this question, the best guide that you have got is to look around your local area and see which species of trees are growing well and/or make up the most of the local woodland. This way you do not have to worry about your soil type or climate -nature has aready shown you what will do well.




natural regeneration of sweet chestnut less than 20 years after this pasture was abandoned. I thinned this area a year ago and removed about half of the less vigorous and poorly formed trees




Also you should have a clear goal in mind, are you planting for wildlife and conservation, or future firewood or timber production. Your main objective could be to screen yourself off from a neighbour or an ugly development, or it could be a combination of all these factors or many others.



Many people say plant willows, everyone knows that they grow quickly, but really what is the point unless you are a basket weaver or your land is a bog (you have very few other choices in this case), they are of generally speaking little timber, firewood or long term screening value.


I would imagine that cutting a large area of willow manually as a short rotation coppice for firewood could be mindnumbingly boring. (I find cutting hazel stools bad enough-they are a lot of work for not much wood). An endless supply of small round logs that are difficult to stack and burn away quickly on the fire. Volume production isn't everything when considering what species to plant. I am sure that these are great for totally mechanised woodchip production for biomass.


Poplars are also often advised, these are certainly quick with 2-3 meters per year possible with some of the newer clones. They have little firewood value but do have a timber value if they are grown and managed in the right way. I must say that a poplar plantation is about as interesting as the highly disliked conifer monocultures but without the winter shelter.


Another suggestion made by people who are just looking quick wood is the Foxglove tree (paulownia tormentosa) which can be grown to sawlog size in Europe in as little as 8 -15 years. This is a native of China and although its a rapidly growing tree it can also be very invasive. Recent advances in breeding have lead to clones being introduced that can resist temperatures of -15 celsius possibly even -20 celsius. As a wood it is lightweight being around half the weight of oak. It is also noted as being highly fire retardant, so perhaps best avoided as firewood! As a tree it is promoted as not subject to pest problems in Europe, there is a good reason for this-none of our native insect species can feed on it. Pollinating insects however do well as it produces very showy white/pink or purple flowers depending on the species.


After well over 30 years of looking at woodlands I have come to the conclusion that the best form of woodland establishment is to mimic the way that woodland normally colonises new ground. For example in my area any previously cultivated land that for whatever reason becomes abandoned is rapidly covered by blackberry, broom, silver birch, willow,aspen,alder and hazel.

Ok, you would be mad to want to plant blackberry and broom but it is easy to see that the birch and the others are colonising species (oak can also colonise grassland too if the conditions are right).




Oak natural regeneration at 5 years from germination. I'll keep the neighbouring broom bushes under control so that the oak is not crowded out















One the birch starts to gain a little height other tree species start to appear- oak,sweet chestnut, ash perhaps a scattered scots pine or douglas fir and finally beech. These grow better after the site conditions have been made more suitable for them by the colonising species. The colonisers are quick growing but generally short lived so that when they die they are replaced by the secondary species of tree that then go on to make the dominant trees over the longer term.


The problem is that everyone who plants trees wants it to look like a woodland as quickly as possible. It is my conclusion that you should plant a mix of colonisers planted for there quick growth and the other species that are going to make up the longer term which could at sometime in the future become a valuable asset.






7 year old self seeded scots pine growing together with sweet chestnut, beech and silver birch














This will however lead to future problems. It is likely that without management the quick growing pioneers will overtop and surpress or even kill the slower growing "crop" trees. So you need to be in there watching and managing your woodland, always keep in mind your long term goal(s) You cannot just let it do its own thing or your not going to get the result that you wanted.






Douglas fir that I planted 5 years ago inamongst my hardwoods-naturally regenerated sweet chestnut and ash and planted beech. As you can see I don't tend to plant in rows and prefer to plant in groups between the trees seedlings that arrive naturally. It gives a more natural appearance but does need managing regularly to prevent overcrowding problems.






It doesn't really matter because trees grow slowly don't they? Well they can but they don't have to. Everything that you do from even before you plant the trees influences how fast they will grow and develop. Think of your trees as you would the plants in your garden, if you neglect these and don't give them there optimum conditions they perform disappointingly. The same applies to your trees. I shall try to cover these issues in later posts.


Finally to the issue of conifers. To many people these are to be avoided like the plague but in my opinion they do have a valuable place in the woods. Firstly as an economic value, last year I felled 2 large douglas fir, 47 years old. They gave me wood to the value of over 800 euro's. Ok I had to fell the trees,extract them and get a mobile sawmill in to process them. But this is in only 47 years, if you grew an oak or beech you would usually need to double or triple that age to get something of a decent value.


At age 47 an oak can show great promise but not great financial value. I'm not saying lets plant only douglas - private forestry already does more than enough of this around here, but why not plant a handfull or a few dozen conifers inamongst your hardwoods? The birds like them for nesting and winter shelter. They are useful for screening and also add a bit of body to your young woodland during the winter months and can have a highly beneficial nursing effect on your broadleaves. Many species can be removed for Christmas trees. You can think of conifers as a temporary but beneficial addition to your woodland or leave a few for perpetuity like I do.

The Ginkgo Trees of St Sulpice Lauriere (87)France

Pictured below are the magnificent Ginkgo trees of St. Sulpice Lauriere in their full autumn splendour photographed during the first week of November.

They were planted in 1864 during the construction of the Paris-Toulouse railway and are thought to be the finest linear planting in France.

If you would like to purchase seeds collected from these trees, prices and purchase information are to be found at the bottom of this page.


The Ginkgo or Maidenhair Tree as it is sometimes called is a remarkable tree, fossils of related species date back 270 million years. During the time of the dinosaurs it flourished across the world before undergoing a rapid decline with an eventual disappearance from North America around 7 million years ago and extinct in Europe 2.5 million years ago. Even in China where it was discovered there are no recent fossil records and until it was seen by the first westerner in 1690 was thought to be extinct. It is not even certain that wild populations of this tree still exist in china and it may owe it's survival to Buddhist monks who cultivated it in the temple gardens where specimens exist that are thought to be in excess of 4000 years old.

If you are interested in finding more indepth detail about anything and everything to do with the Ginkgo tree visit The Ginkgo Pages http://www.xs4all.nl/~kwanten/


The history of our ginkgo's in St. Sulpice Lauriere starts in 1864 when the chief railway engineer M. de Leffe invited the imperial prince of Japan to stay at his chateau near Limoges. The imperial prince brought with him 13 young ginkgo trees which M. de Leffe had planted at the newly built station at St. Sulpice Lauriere. At this time the tree was mostly unknown in the West. Of the 13 trees planted, 12 survived -9 male trees and 3 females and have flourished to become such an impressive sight today.

It is a truly remarkable tree, not only is unlike most other conifers, being deciduous and having very unique broad leaves. It bears fruit that look like apricot coloured plums that have the most powerful stench. It is also highly pollution tolerant, resistant to insect,virus,fungal and bacterial attack. When the first atomic bomb was dropped on Hiroshima on the 6th of August 1945 the only thing left alive were 6 ginkgo trees, the closest of which was only 1130 meters away from the epicentre of the explosion and they are still alive today a remarkable example of the tenacity of life.


So if you are ever passing our quiet corner of the Haute Vienne take 10 minutes to pop down to the station in St. Sulpice Lauriere and marvel at these truly amazing living fossils.



























This is the plaque at the station telling the story in french of these trees. If you want to read it in better clarity have a look in my ginkgo album on picasa click on the link on the top right of this blog.

Infact the plaque below incorrectly states that there are 10 male trees and 2 females. This is wrong, this autumn there are definitely 4 female trees bearing fruit, so therefore there can only be 8 male trees.




















If you would like to try to grow some of these most ancient and fascinating trees you can purchase seeds that I have collected from the trees written about in this blog post.


The seeds are priced as follows.

5 Seeds £0.99
10 Seeds £1.65
25 Seeds £2.75
50 Seeds £4.85
100 Seeds £9.00
250 Seeds £23.00
500 Seeds £44.00
1000 Seeds £80.00

You can email me to discuss and reserve your requirements. Postage costs to the UK and European Union are £1.90 extra.

The seeds require around 12 weeks of pre-treatment before they will germinate, this is not difficult to do and I include free information on how to do this with every order.

And finally pictured below, one of the male trees is particularly easy to identify!

How to build a log skidding arch

Anyone who has viewed my log arch web album will have seen a piece of equipment almost identical to the one in the picture below. This was made in a weekend by Steve from West Virginia and his friends Ed and Mark.
If you click on the album cover below it will open out into a step by step photographic record of how they contructed this simple but highly effective log skidding arch.
This was of course the inspiration for my own. It is constucted using an engine hoist as the main body, then adding a towbar, an arch structure to support the log and to add ridgidity to the frame and finally a pair of stub axles, hubs and wheels.


CLICK ON THE PHOTO TO OPEN THE CONSTRUCTION
PHOTO GALLERY
 For my own arch I purchased a 2 ton engine hoist from Carrefour (France) for 189 euro's delivered, 52 euro's worth of 3mm box section steel and a pair of stub axles and hubs from Autow warehouse (UK) for around 60 euro's. I already had a suitable pair of wheels. So allowing for a can of spray paint and a pack of welding sticks it cost me about 310 euro's.
In addition I also bought an arc welder, mask and gloves as I had never done welding before.
So this was my project that taught me how to weld, a skill that has been really useful over the last 2 years. Once you learn a skill like this you find so many applications for it and you wonder why you didn't learn it years earlier.
It is amazing the size of log that you can haul out using a log arch, even with my tiny 12hp kubota I have pulled out 3m lengths of Douglas Fir 70cm in diameter. Although it helps if the ground is not too wet and the hills not too steep!

This log had to be pulled up a steep hill to get it home so I added a "back axle" to the log held on with a ratchet strap. It worked very well once I had worked out a technique of getting it under the log!
So thanks Steve for putting this album on the web, without it I would never have made my log arch, I would not have learnt to weld, most of my logs would still be stuck in the woods and my fledgling timber enterprise would still be just a dream.

Tree species guide for firewood

Here is a guide to the firewood qualities of each type of tree that we have growing in this part of southwest France.

Sweet Chestnut.
castanea sativa

Sweet Chestnut small roundwood from the first thinning of the coppice at 17 years.
These really need 2 years to dry out properly as they are unsplit.
This species makes up about 50% of my woodland. This wood must be split to enable it to dry out. If
left unsplit it will take years to dry out even if it is covered. Straight, knot free pieces are a pleasure to split parting easily and cleanly. Old, twisted and knotty pieces can be nearly impossible and it saves a lot of time and frustation if you precut through the knots with the chainsaw. On reasonable sized knots it is best to either steer well clear of them or to go for a split that will run right through the centre of the knot splitting the base of the enclosed branch. The latter is a technique that works well for me. Usable the following winter but larger pieces are better for leaving for the one after!

Silver Birch.
betula pendula
This makes nice firewood. when dry it's light weight and burns well. It must be split within a few months of felling or it will rapidly deteriorate even if kept dry. I guess the bark must be waterproof and the humidity within the wood cannot escape so that the wood that has absolutely no natural rot resistance turns to mush leaving just the outer circle of bark. The basel 50-80cm of a birch tree of any stature is an absolute sod to split even by machine. It is so tough and stringy. Best solution is to cut into short lengths of 30-40cm for splitting. I still sometimes even for these short lengths need the help of the chainsaw to cut a full log round in half. In general the wood is a little stringy and a hand axe or small chopper is a great help for cutting through the last persistant fibres. In a sunny spot it dries very well for use the following winter.

Beech.
fagus sylvatica
A lovely firewood - one of my favourites. Once again it must be split within a few months or it will start to deteriorate becoming mottled (spalted) in appearance as it becomes invaded by fungal colonies. It has no natural resistance to rot so it must be kept dry. It splits fairly easily and cleanly except for the lowest 50-100cm of the trunk. Cut this part into short pieces for splitting. If you take the effort to follow these guidelines it is super firewood. It dries easily for use the following winter and burns well with a good sustained heat.

Ash.
fraxinus excelsior
Widely regarded as the best firewood. When freshly felled it naturally has a low moisture content and lovely white wood. It will dry well even when not split. It is a little stringy at times which can make it a little difficult to split. It is however well worth the effort. Unfortunatly it is only a minor species in this area growing mostly in the valley bottoms on the more fertile and humid soils. The few trees that I have tend to be of great form and are much too good for firewood. I normally use only the branchwood for firewood production. I plant and encourage the regeneration of ash more than any other tree. Please try to do the same if you can.

Oak
quercus robur
Great firewood but it can be quite hard work to produce. Open grown trees are very knotty and these are hard to split. This is easiest to do when the wood is still very freshly felled. Cut through the larger knots with the chainsaw and or cut into short lengths to make splitting easier. Keep the logs dry or the sapwood which is often quite a large percentage of the log will quickly rot away even on split wood. If the logs get repeatedly rained on they produce several types of fungi which are soft and slimy and not a pleasant experiance without good gloves! Small splits will dry before winter but all larger pieces need an extra year or even two to get the full potential from this hot burning, long lasting wood.

Hazel
corylus avellana
Don't overlook this as a source of firewood. The wood dries well without splitting and burns nicely. Hazel is a quick growing species that coppices readily and will provide with a good crop of round logs and kindling if cut every 12-20+ years. As this grows as a dense cluster of stems make the first cuts at about 1m above ground until all the stems are felled and cut up. Then with the chain saw horizontal, cut through the top of the stool to cut free all the 1m legths that are still attached to the it- of which there can be well over 100 individual stems. This technique taught to me by my old french neighbours greatly reduces the danger of kickback caused by the guide bar tip touching the crowded stems.

Lime
tilia platyphyllus and cordata
It's wood and it burns when it is dry is about all you can say from a firewood perspective. Don't make an effort to aquire or produce firewood from it, but if the tree has to come down use it.

Fruit tree wood
Malus and Prunus species
These burn well but are usually a pain to split especially with old knotty trees


Willows
salix species
Found growing on damp or boggy soils. We have a lot of this, I have found this to be a better than expected firewood. It dries well both split or unsplit. It burns a bit quickly and therefore I would never sell it to anyone. We burn it at home as well as all the other odd left over pieces of wood, the horrid knotty bits, partly rotted logs etc. and find that they all burn and heat the house pretty well.

Wild Cherry
prunus avium
One of my favourite trees so I never cut them down unless they are almost dead or they blow over. The wood burns well but should be split first for drying. Any good straight stems should be planked and used for something better than burning!

Sycamore and Norway maple
acer pseudoplatanus and acer platanoides
Easy to split and burn pretty well. They are both only very minor species in this area so I don't get to cut a lot of either.

Conifers
abies, larix,picea, pinus,pseudosuga etc. species
I have used many species of conifers for firewood and have found that they burn fairly well, but quickly. They have a more open wood structure and therefore dry more quickly than hardwoods. For splitting I always cut them into short pieces about 30-45cm in length and always split around the knots.

Firewood



If you start to manage a woodland it almost certainly means that some of the trees will have to be felled. It makes sense to remove the trees that are poorly shaped or overcrowded to give more space to the trees that are of better form and have the potential to grow into quality timber. Therefore you need to do something with the wood from the trees that have been felled and firewood is an obvious solution.

I always fell the trees after the leaves have fallen during the winter months. This way it causes less disturbance to the wildlife especially nesting birds. It is also too hot here during the summer months for chainsaw work. I find that even in winter within a few minutes of starting to cut I am down to my T-shirt. So I stop felling in early April and then spend 3-4 weeks bringing all the wood that has by now been cut into 1 meter lengths out of the forest and to a clear open area where the logs will later be split and stacked. It is essential that this is a sunny spot where the breeze can blow through to dry the wood. If the split wood is not stacked in the sun their is no chance that it will be dry enough for it to be burnt the following winter.

For the last 10 or so years I have split all my wood by hand using a combination of steel wedges and a 2.5kg log splitting axe. I could generally split about 1 cubic meter of wood per hour this way. If it was knotty oak it wood take a little longer or if it was nice straight sweet chestnut it could be done in as little as half an hour. I found that a session of up to 2 hours was about right for me and I split about 130 cubic meters in total during April and May of each year. Splitting this volume of wood by hand however did lead to the development of very painfull tendonitis in both elbows and forearms. It had got to the point where I had to mechanise the wood splitting or cease production.

Not having much cash for investment I looked around for something a little different to the usual log splitting equipment. On Ebay I found a rotary wood splitter called The Stickler (www.the stickler.com)which is bolted by means of an adaptor plate onto the back hub of almost any rear wheel drive vehicle. It costs around $279 and $130 delivery to France, although this was discounted by $50 as they were offering free delivery in the U.S. at the time.














The Stickler in action using my battered 1993 Toyota Hiace as the muscle power


With this extremly efficiant tool I was able to split over 200 cubic meters of wood over the course of 4 weeks working 3-4 hours per day. The cost of this was around 60 litres of red diesel but I saved myself a great deal of fatigue and physical damage. With the help of a second person the wood could have been split much quicker. I lost a lot of time getting the logs to the splitter and then stacking the splits. The finishes log piles are then immediatly covered with plastic sheeting to keep the rain out. This way with our usual hot summer the wood is ready to start being delivered during August to my loyal group of customers.









Part of a finished wood pile, this one represents about a quarter of the total firewood split for this year

What's wrong with forestry today?



I took these photo's today, close to where I live and it is an absolutely typical example of the type of forestry that is practiced around here and in so many other places too. This piece of woodland was a very prominent landscape feature and now it has been felled it is even more eye catching to the many thousands who drive past it each day.

From counting the growth rings this wood represents over 70 years of growth since it's last clear felling. It appears to have been completely unmanaged and by consequence has grown into a low quality, low value crop with virtually all the timber being sent to the local pulp mill where it has a value of around 19 euros per ton. An entire human lifespan to produce an almost valueless product. But it didn't have to be that way. Just a little bit of periodic management to thin the overcrowded trees and remove those of poor form would have concentrated the growth potential in the remaining better trees, which could of then grown on to be of a high enough quality for saw milling and be worth 10 to 20 (or even more) times as much. Still taking the same 70 years to grow and mature.


Large areas of woodland should never be clear felled. A forest is a living entity that modifies the soil it grows in, moderates temperature extremes, reduces windspeeed, increases humidity, greatly reduces rainfall runoff and many many other additional beneficial factors as well. When it is felled, in a moment all this is lost. It becomes a micro climate of extremes. Today it was baking hot and it was as if the whole site had been sterilised. There was not a bird, beetle,bug or animal of any kind, absolutely devoid of all life. You could then step from this into the part of the woodland which still remains (for the time being). It was like walking through a door from one room to another - totally different in every way. There surely has to be a better way than this to manage our forests.


So what is the future for this wood? Well as long as it is not cleared for housing or agriculture it will eventually recover. Already some of the cut stumps were showing signs of life. The regrowth is surprisingly quick. The sweet chestnut can grow up to 3 metres in the first year here after being felled.
