Ancient wood, woodworking and wooden houses
In May 1987, the subcommittee on of the European Science Foundation (ESF) organised a workshop on “the of wooden buildings from the prehistoric and early historic period”. (...) The 1980s was the beginning of a boom in the of archaeologically inspired buildings inside and outside archaeological open-air centres. In their proposal to the ESF, they wrote of the problems of constructing at a 1:1 size. Some of the problems addressed are still valid today.
This article introduces a record on the management and use of prehistoric woodland gained from the research of the Somerset Levels.
The Somerset LevelsIn efforts to understand how ancient people obtained supplies of for their houses, barns, fences and other equipment, archaeologists often have to rely upon a record that has barely survived time‘s of destruction. The raw material most consistently and abundantly used in ancient times, and in fact into the 20th century in some areas of the world, has not often been preserved for detailed study, and even where traces survive, their quality may be unsuitable for scientific research. Where ancient wood has been maintained in a good condition, archaeologists have an obligation to extract as much useful information as possible, as their results may be relevant to other archaeological situations where conditions of preservation are not as good. It is, of course, important to remember that the woods available and used in certain areas, where they have survived, may not be exactly comparable to those of other areas where is poor, and care is thus needed in extrapolation of results. Nevertheless, there are important reasons why archaeological sites and regions containing abundant preserved wood can be used in the of a general assessment of ancient woodlands and wood , so long as care is taken in utilising the results. In this paper, one area where preservation has been exceptionally good will be used to show the character and quality of evidence that can survive, and this will be used as a guide to the woods used in the construction of ancient buildings.
The Somerset Levels are an area where conditions for the preservation of the environmental and cultural records allow some degree of generalisation about prehistoric woodlands and . Due to extensive peat formation over 5,000 years (4,500 BC - AD 500), the peat bogs buried hundreds of ancient structures, and because the area is low and flat, silts and clays have also helped seal many sites from decay (Coles and Coles 1986). The advantage of a wetland such as the Levels is that it contains within its peats not only the wooden elements of trackways, platforms and other structures, including houses, but also the record of the woodlands growing in and around the area. Pollen analysis, allied to macroscopic identification of leaves, seeds, and , and the wood of structures, provide an important record of the changing use of primary and secondary forests, the development of woodland management practices, and the exploitation of preferred species for particular purposes. Allied to experimental work in the Levels, we can now make some suggestions about ancient wood technologies, from species selection to felling, splitting and working, and also about the likely yield from various kinds of woodlands of the timber and roundwood needed for structures.
Such differing varieties and qualities of wood have important implications for the character of ancient structures, just as has the development and use of different tools for working of wood. The felling, splitting and working of a variety of woods, and the use of both roundwood and timber, is represented in the Levels by 100,000 recorded Neolithic, and wooden artefacts from the trackways, platforms, houses and dumps so far identified, and by several million pieces of wood observed over the past 25 years. Some of the archaeological evidence for primary woodworking on a variety of trees through time will be examined in the paper, and suggestions will be made about the implications for the 'wildwood' through such activities.
Classifications(See Rackham 1980)
Timber is sometimes used to describe trees large enough to make planks and beams. In this case, the word wood is reserved for smaller trees suitable for poles, rods and other small-diameter stems. Most wood consists of underwood, grown by a coppice system, in which a tree is felled and the stump thus encouraged to send up shoots or stems; in time the stump or stool yields many crops of poles and rods, felled at intervals dependent on the length and diameter of the poles or rods required. Branch wood is mostly unsuitable for building purposes, and is one of the principal sources of firewood (see below).
In a prehistoric woodland where some form of control was exercised there would be both timber, or timber-bearing, trees and wood, or underwood or roundwood, of more slender dimensions, all growing together in a system sometimes described as coppice-with-standard. The underwood in England might be elm, hazel, ash or lime, and timber trees would be oak; conifers would be represented in Alpine regions, birch was important in parts of northern Europe, and cedar was pre-eminent in northwest coastal America.
In the Somerset Levels, we accept these basic definitions, but for the recording of pieces of prehistoric wood found in the trackways, platforms and collapsed houses we use the terms timber and roundwood. Timber refers to split wood, as distinct from roundwood which is an unsplit stem or branch. The division between the two categories may be blurred when dealing with half or quarter trunks; in the Levels these are described as split roundwood, and timber is reserved for pieces which have little or no outer surface remaining. Timber may be further classified on site as planks (length circa 1.0m - 10.0 m or more; width circa 0.15 - 0.50 m or more; thickness 0.15 m thick. Many pieces are found broken and so such definitions are often difficult.
Felling and axesThe evidence surviving from the Levels allows some observations to be made about the felling of trees, and in the use of different axes of , bronze and iron. It is very unusual to recover any direct evidence of the felling operation itself. However, tree-stumps occasionally survive in the Levels‘ peats, and show the precise of felling, e.g. very acute chopping, around the whole stem, marks the felling operation on yew circa 1,500 BC. The chopped ends of stems and branches are less reliable as they may have been re-worked after felling. Timber burnt at one end may suggest the use of to assist in felling, but only if, as in the Levels’ evidence, the wood was not being re-used from earlier structures. Because trees once felled were most often cut to shape, it is only the rather rough substructural components that preserve traces of the felling operation.
The size of trees felled in different periods may be compared, taking evidence mainly from the Early Neolithic and the Bronze Age. The evidence is largely derived from estimates of total tree diameter based on examination of the tree-rings in the cross-section of planks. These indicate that stone axes could be used to fell trees at least as large as those exploited in later periods. Neolithic stone axes were adequate for clearing primary and secondary deciduous forest, including oak trees up to one metre thick and 350/400 years old. Most of the Bronze Age oaks observed were only 30-50 cm in diameter, but that is a reflection of the woodlands in the Levels rather than the tools. The gross size of woods used in the structures gives a general impression of the nature of the wood species available, although tree-ring analyses are also required to obtain a better picture of the quality of trees.
RoundwoodRoundwood is an easy term to appreciate, as it is the basic state which is encountered. For archaeological recording of roundwood in a structure we use our descriptive terms carefully while admitting that wood, being a flexible medium, allows infinite variation in the ways by which it may be worked. For roundwood there are seven obvious elements to consider; species of wood, whether green or seasoned, its growth rate, the type of , angle of cut, shape of product and character of facets (Coles and Orme 1985).
TimberIt is likely that the bulk of trees were processed soon after felling and not left to season. The rate at which a tree dries, or seasons, depends partly on species; of the timber trees discussed here, alder is relatively quick and a tree felled for six months is noticeably different to work to one that has just been cut down. Oak is slow to dry, and may be worked ‘green’ for up to two years. Ash is intermediate, perhaps closer to alder than to oak. No information is available to us for lime owing to its present scarcity, and elm of recent years has all been well-dead, thanks to disease.
Side branches would be trimmed from the felled trunk before splitting, and topwood removed to leave the bole clean. In the finished timber occasional knots and quirks in the grain indicate where side branches once grew. An overall impression of the prehistoric timber from the Levels suggests that there were few side branches on the trunks felled for timber, indicating that the specimens had grown in close competition with other trees, probably in a forest, although a considerable number of pieces from the oak forest of ca 1,500 BC were distinctly twisted. The timber recovered from the Levels consists predominantly of planks and stakes, with some Iron Age beams, and in discussing the conversion of trunks the production of planks will be considered first. From the Neolithic, planks up to 5 m long are known; these are of ash and lime. The oak planks occasionally exceed 3 m. Bronze Age planks have been rarely preserved over 2 m in length but 5 m lengths exist and there are records of timber of ca 10m length (Orme and Coles 1983).
Wedges and beetles(Darrah 1982)
Seasoned oak chips make suitable wedges, but unless they are well-preserved on sites, they may not be distinguishable from ordinary chips detached in preparing wood. Wedges heavily used in splitting will often bear clear signs of such use, in compression, curvature, splitting and burring of the head. Due to the great weight of freshly-felled stems, splitting would be logically carried out in the woodlands, and so wedges may well not be in great abundance on the sites of structures themselves; nonetheless, wedges for secondary splitting may well be present.
Mallets are tools requiring more preparation, and represent fine examples of the woodworker‘s . Made from stem and branch intersection in one piece, or from the insertion of a straight handle into a heavy chunk, they should survive in waterlogged conditions. From the Somerset Levels, only one Neolithic mallet has been found, but there are several later and smaller specimens; the Neolithic mallet was made of yew, one of the toughest native species of the British Isles. This mallet showed its use as a heavy blunt instrument, in the burring down of the inner parts of the rounded ends. The use of such a tool was either to drive pegs or piles, or to force wedges into tree stems in the early stages of timber or plank production. Experimental work shows how easily fresh oak, and ash, can be split with wooden wedges and beetle, and our work suggests that a heavy oak tree once felled could be reduced to 8ths or 16ths within an hour or so, granted a stem without major imperfections. Prehistoric timber from the Levels occasionally carries the traces of wedge 'burring' (Orme and Coles 1983). Normally however it would be expected that the further trimming of split wood, or its use in structures, would remove or disguise such primary signs. Nonetheless such traces should always be sought.
In experimental work, oak can be shown to split easily and cleanly, but ash is generally a more difficult proposition, particularly if many side branches and knots occur. Alder is relatively easy to split but birch in contrast is more resistant and sappy. In all these operations it is not force that is required, but the eye of the worker in turning the wedge to follow the line, and to bypass or force through the more convoluted parts of the stem. In this work, it is noticeable that when completed, the faces of the plank will bear traces of clean splitting of the wood interrupted by burring of the faces where the wedges were forced in and often the wedges will remain stuck between the main face and a slender but resistant sliver of wood stubbornly attached to the wrong side. In such cases the sliver would be axed free. Such slivers have been observed on Levels‘ sites.
The Bronze Age examples range from redirected radials to true tangentials. The pieces intermediate between radial and tangential are split across the primary natural planes of weakness in oak, namely the rays, and across the growth rings which can also allow easy splitting. Theoretically, these examples are the most difficult to produce, yet they are found in both Neolithic and Bronze Age structures. The true tangentials are relatively small timbers, and may have been produced by secondary splitting of a hefty radial. Lime tree-ring samples provide some information about the working of this species in the Early Neolithic; they appear to be rather thick tangentials split in two down the centre, and true tangentials have been recorded.
Although there are relatively few planks and beams from the period c 500 BC - AD 500, those that survive from the Iron Age settlements reach 3 m or more in length and often bear signs of axe or adze on their surfaces; they were presumably split radials later truncated. Of particular note are the slats or slender planks interpreted as loom parts, from Glastonbury; these were mostly of ash and some were said to have been adzed. The thinness of some of these slats, down to 25 mm, suggests a high degree of skill and experience in working with wedge and axe or adze. Indeed, a few smaller pieces were split to under 5 mm thickness.
SapwoodIn the majority of oak timbers studied recently from the Levels, the sapwood was trimmed off. The discovery of chips of sapwood indicates that this stage in the wood-working was sometimes carried out at the place of construction. Sapwood chips have rarely been identified, though, and it is likely that the planks were generally trimmed soon after splitting, before being taken to where the track was to be built. For example, of 115 pieces of timber used to build up a Bronze Age chronology eight retained sapwood and the rest had been trimmed, or originated in the inner part of the trunk. Very occasionally, axing has been evident down the side of a plank. Sapwood rots more quickly than hardwood and its removal delays decay of the timber. Oak has a marked sapwood zone and elm has approximately 20-30 sapwood rings but lime is less clear. It is not surprising that even in the Early Neolithic, sapwood was almost always removed from timber; the structures built involved considerable pressure on plank edges, and a sapwood edge would rapidly collapse.
BuildingAlthough there are many thousands of planks and posts known from the prehistoric structures in the Levels, there is still relatively little evidence of Neolithic and Bronze Age buildings. Ash, oak and lime planks, unneeded for the contemporary buildings of the Early Neolithic, came to rest in the marsh, and they show that structures of the period could have contained planks 5 m long, and up to 40 cm wide, split and worked into remarkably uniform timber. Bronze Age timber includes planks of oak up to 10 m long, as well as heavy beams. All of these planks could be perforated to take pegs or posts, or ties. For the Iron Age of the Levels there is ample evidence for buildings at the settlements of Glastonbury and Meare. The advantage of the Somerset Levels is that it shows not only the character and quality of woodworking of the Neolithic, Bronze and Iron Ages, but it also demonstrates the nature of the woodlands from which the raw material for structures was obtained. These factors can be used when we turn from the Levels to the wider field of ancient buildings and the character of the wood used in them. We will approach this in two ways, the first concerning the size of trees, and their yield of timber and roundwood. The second approach will be directed towards particular types of structure, in an attempt to estimate the quantity of wood needed in their manufacture.
If we take three sizes of trees such as are known from the Somerset Levels, we can calculate their yield of roundwood and timber for house posts, walls and floors. Tree A, the largest, existed in primary or long-established woodlands; it had a stem diameter approaching 100 cm, and a clear stem length of 12 – 15 m. before major branching. If of oak, it could be circa 400 years old, but other species such as pine could be less old. A tree of this width, if of oak or other suitable species, can be split radially to make at least 16 planks, each circa 13 m long, circa 40 – 50 cm wide and 12 – 15 cm thick near the (trimmed off) sapwood. Tree A thus yields 16 × 13 × 0.45 = circa 93 square metres of planking. Such a tree might also be split radially into more than 16 thin planks, given an evenly-grained tree and a skilful worker. We will calculate below on the basis of circa 90 square metres of planking from an A tree. The stem could be used as a heavy roundwood post, but branch wood was restricted in useful lengths to perhaps 50 m in total. Tree B existed in secondary woodland, previously cut-over and opened out, so clear stem length is reduced; if oak, it was 100 years old, with a stem diameter of 40 - 50 cm and a usable stem length of 10 - 12 m. A tree of this width can only be split tangentially if relatively wide planks are needed; it would yield four planks, each 10 m long, circa 35 – 45 cm wide and circa 8 cm thick. Tree B thus yields 4 × 10 × 0.4 = 16 square metres of usable planking. If radially split, into eight planks each only 25 cm wide, the yield is about 20 square metres. Otherwise, the roundwood yield is 10 m of thick stem, and perhaps 100m of useful branch roundwood in short lengths.
Tree C was a younger stem, again in secondary woodland, possibly coppiced oak, ash, lime, or other species such as pine; if oak it was 40 - 50 years old, if pine a younger tree, with a stem diameter of 20 – 30 cm, and a length of 3 – 5 m or so. It would be split tangentially for planks 20 cm wide, or radially for 10 - 15 cm wide timber, and the yield was about 4 square metres per tree. Note that it is the size of trees that we are dealing with, not the species. The stem could also serve as a heavy roundwood post; branch wood would be rather weak.
The archaeological record from the Somerset Levels and elsewhere speaks of managed woodlands from the Early Neolithic onwards, and of the fact that many trees were coppiced. It is not only ash, alder and hazel that were controlled in this way; oak was too. The point to make is that managed woodlands could and did yield vast quantities of useful wood for all the structures that have survived into the archaeological record, and for most of those that did not as well.
Although our interest here is in the wood for buildings, we should not forget the need by ancient farmers and others for wood for fences, for equipment and above all for firewood. Many records exist for the historic period which speak of the sole reason for the abandonment of a as being the exhaustion of wood for fires.
HousesLet us now consider the timber requirements for several different kinds of houses such as are known from the prehistoric and early historic periods in Europe. First, however, there is one obvious remark to make. It will be obvious that different wood species have different characteristics, whether roundwood or timber is created. For example, in its ability to bend, and tendency to split, break or erode, a pine log will differ from an oak log, and an oak from an ash. Even within a single species, there can be considerable variation in growth rate and therefore density and strength. For example, an oak slow-grown in a dense forest may achieve a diameter of 35 cm in 100 years; as a coppiced oak, in a favoured , it could reach the same diameter in 35 years. But although of the same size, its strength will be different, as a slow-grown more densely-ringed tree will be in general stronger than a fast-grown less densely-ringed tree. But there can be exceptions to this in terms of, e.g. the degree of bending which a piece will sustain, and this feature alone is often the most crucial in selection of wood for structures. In addition, different parts of the same tree will yield wood of different densities, and hence its ability to be worked and to serve as a load-bearing element; branch wood tends to be more dense than stem wood, and rootwood the least dense, although there are exceptions.
The age of the wood used is an important element in any consideration of ancient buildings and modern reconstructions. At the Neolithic settlement of Hornstadt-Hörnle, extensive tree-ring analyses have shown graphically the variety in age and size of oak timber used in the house constructions over about 80 years (3586 - 3507 BC) (Billamboz 1985). The earliest structures were made with 100-year old B trees, radially split into 1/8, 1/12 or 1/16s. Structures built 15 - 20 years later used a mix of B and C trees of 50 - 80 years age, many of smaller diameter; these were split into 1/2, 1/4 or 1/8s. Thirty years later a further group of even younger C trees were used, from a regenerated woodland started at the time of felling of the first episodes; these trees were only 40 years old and of small diameter, split into 1/2 or 1/4s. The final episode of building, some 15 and 30 years later, used B trees from an old stand of oak, over 100 years old, and the wood was split into 1/12 or 1/16s. This final wood may have been standing in a 'standard- width coppice' woodland but is believed to be a different old woodland than the first which had been felled 80 years previously.
There are, broadly speaking, two different ways of using wood in the construction of ancient houses. The first is by utilising the properties of oak and other trees of large diameter to make planks. The other is to use the round stems, or large branches, direct without splitting. In both cases, wall infilling may be by split timber or, more often, by woven . We will look now at several different kinds of houses to estimate their requirements for timber or roundwood; most of these house forms are based on actual excavated examples, and we concentrate on floors and walls rather than the more problematic roofs.
House 1 is 40 m long and 10 m wide with plank walls 2 m high, and it has a plank floor. Thus, 600 square metres of planking is required. That is 6-7 A trees at 16 radials per tree, or 30 B trees. The timber and poles for the roof of this house might require 4 more A trees or 20 B trees.
There seems little point in estimating the time needed to fell and split this wood, as efficiency of ancient tools and men is unknown, but experimental work suggests an A tree might take one hour to fell and one hour to split into 16 radials. A B tree might take 20 minutes to fell, and one hour to complete 5 tangential splits, or 20 minutes to make 8 radial splits. This is 20 man-hours on A trees, or 120 man-hours on B trees, for this house.
House 2 is a long house, 60 m long and 10m wide with plank walls 2.5 m high and an earth floor, like a Viking Age house. That is 350 square metres of timber from 4-5 A trees or 17 B trees or 100 C trees, or any suitable combination. With buttresses (100 square metres) and upper members (4 A trees or 20 B trees), the totals are approximately 10 A trees or 40 B trees. This is not far off an earlier estimate made for the Fyrkat Viking Age house of 50 trees, presumably of both A and B types.
House 3 is smaller, 10 × 6 m, with front and back walls 2 m high, and 4 m at the ends, and a plank floor; this is like an Anglo-Saxon house in some models. The house would require 2 A trees or 44 B trees or 45 C trees.
House 4 is an Iron Age round house and is based on a well-documented house from the Glastonbury lake village (See Fig 10). It is 6 m diameter with a planked floor area of 28 square metres The floor would require 2 B or 10 C trees which were growing near the site circa 100 BC; A trees were not available. The plans of house 74 at Glastonbury show the ancient planks clearly, and they fall into three distinct groups: 14 planks 0.5 - 1.5 m long, 17 planks 3.0 - 4.5 m long, and 12 planks 5.0 - 6.5 m long. They average 10cm wide. This is 1-2 B trees, yielding about 30 6 m planks, one set cut into unequal segments. In addition, the house had wattle and daub walls, and this introduces the second element in house construction for long, square and round houses of many periods.
The use of woven panels (hurdles, wattles) for house walls, as well as in roofing, is well attested and there are Neolithic, Bronze Age, Iron Age and early historic panels surviving in waterlogged settlements and trackways (See Fig 11). A convenient size is a panel 3 m wide and 1.5 m high, and this requires about 100 rods 3 m long, and 10 sails 2 m long; that is 320 m of rods. The rods might be of hazel, aged 4-9 years and 20 - 30 mm diameter. They were obtained from hazel or other species, grown from stools in a coppiced system of woodland management. Each stool could yield 15 - 20 rods 2 - 3 m long in every cycle, that is, 40 - 50 m of rods. Thus a panel is the product of 6 - 7 stools, and about one hour‘s work (Coles and Darrah 1977). House 4 had 70 stake or sail holes, arranged to suggest 11 panels each about 2 m wide; at 1.5 m high, that is 600 rods and sails, 1200 m of wood and 25 - 40 stools cleared, as well as the 1-2 B trees felled and split. A standard-with-coppice system in an area of woodland of under l00 square metres would hold all these trees.
House 1, a long house, with wattle and daub walling rather than plank walling would need 100 m of panels, say 35 panels from 210 – 225 stools. With timber panel-supports and other structural pieces, 2 - 3 A trees or 10 - 15 B trees would also be needed. A planked floor would also put demands on timber production.
Many houses of the prehistoric and early historic periods in Europe are not plank built, but rather are formed by the skilful relationship of vertical and horizontal roundwood posts and poles, and this has important implications for the character of ancient woodlands. These houses often have walls of wattle and daub, and others have infilled horizontal planks set between the major uprights. Sometimes the wall construction is not uniform, and a major part of the house may be of post and wattle construction, with an end portion of plank construction. Houses of the Bandceramic tradition are sometimes of this type. House 5, based on this model, is 30 m long and 8 m wide, and would need 40 wall posts 2 m long, and 56 planks each 50 cm wide; thus perhaps 10 B trees and 4 A trees. The internal posts for such houses are of larger diameter than the wall posts and this might mean 30 heavy internal posts, 10 of which were 5 - 6 m long from 5 A trees, and 20 of 4 m length from 5 A/B trees. The major horizontal roofing members would total 90 m, from 6 B trees. The overall sum is thus 9A, 5 A/B, 19 B trees. The wall infilling is of course extra, about 5,000 m of rods from 250 coppiced stools; this all could have been growing in about 1,000 square metres of managed woodland with both standard trees and coppiced hazel or other species.
House 6 is a long house of the early historic period in northern Europe and might be 35 m long, 5 m wide; such a house will have 90 wall posts of 15 cm diameter and 2 m long, and 30 internal posts for the roof of 20‑25 cm diameter and 3 - 4 m long. This is about 300 m of B tree 30 stems, say B trees. The panel infilling for 80 m would require almost 10,000 m (about one tonne) of coppiced rods and sails, from 500 stools.
House 7 is a log and plank built cabin from the Iron Age settlement of Biskupin. There were over 100 of these structures at the site. Each required about 10 B trees and 35 C trees, much of it from managed woodland. The whole site, with its palisade, roadways, gateways and outworks would have required a very large amount of wood from a wide area of organised forest. In comparison, several medieval or later timber built houses have been assessed for their requirements. A house 12 × 5 m would have needed about 80 C trees, and one 20 × 6 m would require over 300 trees, mostly of C type. A cathedral with a wide roof span would involve A or A/B trees; Norwich Cathedral is estimated to have required almost 700 A/B trees. But an ordinary large three-decker of the line in the 17th century needed 3,500 A/B trees, from about 900 acres of woodland.
Some may question the precise quantities of wood for these houses, and I have paid little attention to roofing roundwood, but it is surely of importance that the large amount of straight stems, fine timber, and the enormous quantities of rods and slender poles signify the existence of well-managed woodlands with stands of coppiced trees and tall standards. Such woodlands were in existence at least 6,000 years ago, and probably much earlier. Man‘s reliance on wood for more than houses must mean that care and attention was given to the control and management of the trees in his territory. Cyclical felling, and planting of whips and shoots, must have been a feature of life, and the woodlands thus in a sense owned and controlled. The very great value of A trees, and the need to ensure a good supply of B and C trees, as well as the continuing maintenance of the coppice cycles, all suggest an interest on the part of early communities in their woodland resources that was more organised than the term 'wildwood' implies. It was wildwood in part, but domesticated as well.

SummaryAltes Holz, Holzarbeiten und hölzerne Häuser
Feuchtgebiete wie die Somerset Levels bewahren in ihren Mooren nicht nur die hölzernen Elemente von Wegen, Plattformen oder anderen Strukturen wie Häusern, sondern sind gleichzeitig auch eine Quelle für die Waldbereiche, die in der näheren und ferneren Umgebung existiert haben. Sie stellen damit ein wichtiges Archiv der im Laufe der ur- und frühgeschichtlichen Zeit wechselnden Nutzung von Primär- und Sekundärwäldern, zur Entwicklung der damaligen Waldnutzungsmethoden und zur Gewinnung von bevorzugten Holzarten für spezielle Bedürfnisse des Menschen dar.
Die archäologische Überlieferung der Somerset Levels und anderer Feuchtgebiete zeigt die Existenz von systematisch genutzten und gepflegten Wäldern seit dem frühen Neolithikum an, viele Bäume wurden dabei einer Schneitelung unterzogen. Es handelt sich dabei nicht nur um Esche, Erle und Hasel, die auf diese Weise behandelt wurden, sondern eine systematische Nutzung lässt sich auch für die Eiche feststellen. Es ist dabei hervorzuheben, dass entsprechend kontrollierte Waldbereiche eine große Menge an Nutzholz für alle möglichen Zwecke bieten konnten und sicher auch boten, nicht zu vergessen dabei der Bedarf der frühen Bauern an hölzernem Material für Zäune, Geräte und vor allem auch Brennholz.
Bois préhistoriques, travail du bois et maisons en bois
Des tourbières, telle Somerset Levels, cachent non seulement des restes de santiers de caillebotis, de plate-formes de bois et d‘autres structures, y compris des maisons, mais encore un enregistrement du développement des forêts dans la région, elles rendent des témoignages importants de changements d‘exploitation des forêts primaires et secondaires, de l‘évolution de la gestion des forêts et d‘une exploitation sélective de certaines essences.
Des documentations archéologiques établies à Somerset Levels et sur d‘autres sites révèlent la gestion des forêts dès le début du Néolithique, un rajeunissement de nombreux arbres. Il ne s‘agit pas seulement du frêne, aulne ou noisetier, le chêne a été soumis, lui aussi, à cette gestion. Il faut remarquer que les forêts gérées étaient en mesure de produire et, en fait, elles produisaient une quantité importante de bois d‘œuvre; il ne faut pas oublier que les agriculteurs/éleveurs préhistoriques en avaient besoin beaucoup pour pouvoir faire leurs habitations, des clôtures, du mobilier et surtout pour chauffer.
