Tree marking knife; the sustainable forestry tool

    By Michael Smith (Veshengro)
    tree-marking-knife This tool, in German called Baumreisser, and produced, predominately by German and Swiss tool makers, such as Victorinox (Switzerland) and Otter (Germany), has been an important tool for the forestry worker and forester in time past.
    The tree marking knife, the Baumreisser (tree ripper), was used in the past by forestry workers after a tree had been felled and the branches removed used to mark the cutting length depending on the timber grade. Foresters too used this tool in order to mark trees for removal, either small trees for thinning operations or even large trees in mature stands. Those were marked with a cross, an “X”.
    It has, in recent decades, been replaced, some would say superseded, by the spray can and the paint ball gun for marking trees for felling, whether large or small, and even as a marker as to where to make the cuts in a trunk according to timber value and class.
    As far as I am concerned, however, the tree marking knife cannot and should not ever be seen as superseded and replaced as spray paint is not sustainable and that for at least two reasons.
    Spray paint is costly in the long run and while a tree marking knife costs up to $60, depending on quality and source, it will last a lifetime and more, if looked after. Paint, on the other hand, is costly in the long run. While a can of the stuff may “only” cost a few dollars at a time over time it will be much, much more than the cost of the tool.
    The measuring staff of the woodsmen that I have encountered in years gone by in Europe used to have a built-in “bark ripper” for the purpose of marking the place where to cross cut the trunk.
    The folding Baumreisser, the tree marking knife, is better though as the forester can carry that with him easily on a “patrol” and mark trees for removal as and when they are noticed.
    I encountered such a tree marking knife again only recently on the Felco stand at the 2011 RHS Hampton Court Palace Flower Show when the marketing manager showed me one of which they were given boxes and did not really know what they were for.
    Initially even I, as a professional forester, failed to recognize them as I had only encountered them with a fixed blade or as part of another tool and I mistook the took for a hoof knife. Shame on me, I know.
    It would appear that makers – some of them at least – are in the process of divesting themselves of the stock of those tools in the – in my opinion false – belief that the end of the tree marking knife has come.
    The ones that I saw (and of which I was given a box) are made by Victorinox and are, in fact, no longer shown in their range. German makers still seem to produce them though.
    As far as I am concerned we will be looking for this tool in the future again once petroleum – and the pain is based on it – has become unaffordable.
    As far as I am concerned the tree marking knife, the Baumreisser, is far from dead and we will find that we will be happy to still have the skills to make them when the time comes and stocks left.

Con-Lib government selling off Britain's forests

    by Michael Smith (Veshengro)

    The British coalition government between Tories and Whigs is putting forward the framework for legislation to sell off much of the government-owned forests and despite much protests seems to be going ahead with it. Truth is they have to raise money somehow to bring the country back from bankruptcy.

    While everyone in the green sector seems to be up in arms about this suggestion I wonder whether it may not actually be a good idea.

    Claims and comments such as this one “The government is getting ready for a huge sell-off of our national forests to private firms. This could mean ancient woodlands are chopped down and destroyed. Walkers and endangered animals, like red squirrels and owls, would have to make way for Center Parcs-style holiday villages, golf courses, and logging companies” by 38 Degrees ( http://www.38degrees.org.uk) are not helpful as they more than likely are very misleading.

    “We need to stop these plans”, 38 Degrees say, and continue “ancient forests like the Forest of Dean and Sherwood Forest are national treasures - once they’re gone, they are lost forever.”

    I am well aware that to many my suggestion is tantamount to treason and betrayal of green principles but allow me to play the Devil's advocate, for a while at least.

    The claim of “ancient forests” which always, in the minds of the public conjures up forests never touched by the hand of man and never managed for forest products, etc. are entirely wrong. There are no “ancient” or “untouched” forests and woodlands in Britain or elsewhere in Europe bar one or two in the East of the continent that were so inaccessible that timber extraction was not possible. All other forests and woodlands have been used and managed.

    The great forests mentioned by the 38 Degrees group were, once upon a time and that not all that long ago, privately owned or owned by the crown and administered by Agisters and other forest officers and the usage rites were “owned” by the so-called “foresters”, much like “commoners” that had rites to the common of a village.

    Originally British forests were the hunting reserves of the crown and thus had special protection. Other forests and woods were owned by the landowners, the Lords and the Lords of the Manor and the Lairds in Scotland. The state has not been the owner of our forests for long.

    The Centre Parcs-style holiday villages – oh mt G-D what eyesores – are not necessarily on the horizon and that simply because there is no money for building those and there are no customers either. So let's stop with silly claims and scaremongering.

    The management of our forests – the state-owned ones – via the Forestry Commission (most of the British woods and forests are in fact privately owned though most people tend to forget that) – leaves much to be desired, as does that of the majority of our privately owned woodlands and especially of those owned by local authorities and local governments.

    The Forestry Commission was not, in fact, established to protect our forests. It was a commercial government operation to ensure that enough wood was available for the use by the military and especially “vital” industry such as props for the coal mines. That was its primary task. The rest just sort of developed later when amenity had greater value than the pit props. You don't need pit props when you haven't got any pits left.

    Afforestation was the main reason for the creation of the commission in 1919. Britain had then only 5% of its original forest cover left and the government at that time wanted to create a strategic resource of timber. Since then forest area has more than doubled and the remit of the commission is now much more focused on sustainable forest management and on maximizing public benefits. Establishment of new forests and woodlands has gone out of the window, unfortunately.

    The Forestry Commission claims also to be the government body responsible for the regulation of private forestry and claims that felling is generally illegal without first obtaining a license from the Commission. Having worked in forestry, private forestry, for many years this is something rather new to me.

    Apparently the Commission claims also to be responsible encouraging new planting and while it is true that the Commission used to provide grants in support of private forests and woodlands, new planting is something that any forestry estate and forest owner who manages his or her forests and woodlands properly would do without the interference of the FC. In the current climate I am sure we shall see this support of grants fall drastically. Not that, to all intents and purposes, it should ever be needed.

    So, let's not loose too many tears and sleepless nights over the FC losing a couple of its forests.

    As long as the woods are not just clear felled by the buyers for a quick buck – and legislation could prevent that from happening – and are properly managed for future timber and other forest products, which everyone on his or her right mind buying such assets would do, then privatizing many of those forests and woodlands might just be a good idea.

    People could band together and buy their own local forests and then manage them and thus much better use could, maybe, made of them than are currently be made by the FC and local authorities.

    Thus many proper community woodlands and forests could be created and the forests products could be marketed primarily for local use, which could encourage local industry regeneration.

    Personally, I wonder whether the FC itself, which is not a ministerial department but, to all intents and purposes is a Quango, should not be gotten rid off itself.

    While, and I am the first to admit that, its research arm is a most valuable one as far as tree diseases and such go the rest of the operations may not be as useful as claimed.

    I told you I was going to play the Devil's advocate here...

    What we really must get down to is to get the management of our local authority owned woodlands and forests to be put under proper commercial management – somehow managed by the councils – to (1) clean them up and (2) bring in some revenue from the forests products that could be created and (3) by the same way also encouraging the creation of local industries making use of those products. It can be done and must be done, if only to keep the woods and forests in good shape.

    Britain's forests and woodlands are in a mess and we need to, urgently, revitalize their uses. In the West Country there are coppice woodlands that, due to pressure from misguided greenies, have not been managed for decades now because those greenies made claims that those woods were ancient woods and must return to their original state.

    Unfortunately none of them has a clue about forestry operations and those coppice woodlands are in danger of breaking apart, literally, with the thousand or more years old coppice stools simply falling over and that is the end of it. No more woods at all. Shame there are so many in the green movement who do not want to understand that.

    You want woodlands and forests? Make sure you own them and not the state even. If the community and people feel strongly enough there should be ways and means that could make real community woodlands and forests possible. But they then also need to be managed properly.

Old Growth Forests and Ancient Woodlands

    by Michael Smith (Veshengro), RFA

    An old growth forest, ancient or primary forest or ancient woodland, is a woodland of great age that exhibits unique biological features. Depending on tree species and forest type, the age can be from 150 to 500 years.

    Old growth forests typically contain a mixture of large live and dead trees or "snags", while unharvested fallen tree logs in various states of decay litter the forest floor.

    Foresters and botanists use certain criteria to determine old growth forests. Sufficient age and minimal disturbance is necessary to be classified as old growth. The characteristics of old-growth forest include the presence of older trees, minimal signs of human disturbance, mixed-age stands, canopy openings due to tree falls, pit-and-mound topography, downed and decaying wood, standing snags, multi-layered canopies, intact soils, a healthy fungal ecosystem, and presence of indicator species.

    Second growth forest are forests regenerated after harvests or severe disruptions like fire, storms or insects is often referred to as a second-growth forest or regeneration until a long enough period has passed that the effects of the disturbance are no longer evident. Depending on the forest, to become old growth again may take anywhere from a century to several millennia.

    Old growths forests are extremely important as old growth forests are often rich communities of great biodiversity harboring wide varieties of plants and animals. These species must live under stable conditions free from severe disturbance. Some of these creatures are rare.

    The age of the oldest trees in an ancient forest indicates that destructive events over a long period were of moderate intensity and did not kill all the vegetation. Some suggest that old growth forests are carbon "sinks" that lock up carbon and help prevent global warming.

    As said earlier, the characteristics of old-growth forest include the presence of older trees, minimal signs of human disturbance and therefore in Britain and much of Europe there are no real “ancient woodlands” and this despite the fact that many misguided and ill-informed environmentalists claim that there are. The great majority of all those forests and woodlands have been touched by human hands and many until not so long ago. All the woodlands often referred to as thus are in fact old coppice woodlands that have been worked up until the 1950's and cannot every return by itself to Nature.

    Only at the border between Poland and Belarus there is a more or less primeval forest containing the last herds of European bison. Further in the East then, behind the Urals, there it is possible to find real ancient forests and woodlands. All other European woods and forests have, however, at one time or the other, often well into the not so distant future, been worked by man for human benefit.

    The previously mentioned coppice woodlands of Southern England, for instance, if left to “return to Nature”, as is being demanded by those environmentalists that have no knowledge of forestry, will simply fall apart. Without man's intervention the thousand to fifteen hundred year old coppice stools will simple break apart and that will be the end then of those woods.

    For this very reason, e.g. the fact that unless those coppice woodlands will break apart – literally – if not worked in the next couple of years again by woodsmen and underwoodsmen. Therefore, it is of the utmost importance that the use of those woodlands as productive woodlands would be re-initiated. Now would be a good time to start. The coppice stools will otherwise, if not coppiced again in the next couple of years, literally break apart and that will be the end of the trees and of the woodlands.

    While it is often thought that ONLY old growth forests are carbon "sinks" that lock up carbon and help prevent global warming but in a way all forests, ancient and more modern, contribute towards the prevention of climate change. The term “global warming” is rather misleading nowadays as the warming, in fact, stopped about seven years ago and plateaued out and has remained at the same level ever since. Climate will, nevertheless, still change until the temperatures will fall again, as they have always been doing in this cyclic changes the Earth seems to be going through every 1000 or so years.
