FORESTS AND FORESTRY  . Although most See also:

people know what a See also:forest (See also:Lat. foris, " out of doors ") is, a See also:definition of it which suits all cases is by no means easy to give . Manwood, in his See also:treatise of the See also:Lawes of the Forest (1598), defines a forest as "a certain territory of woody grounds, fruitful pastures, privileged for See also:wild beasts and fowls of forest, See also:chase and See also:warren, to See also:rest and abide in, in the safe See also:protection of the See also:king, for his princely delight and See also:pleasure:" This See also:primitive definition has, in See also:modern times, when the economic aspect of forests came more into the foreground, given See also:place to others, so that forest may, in a See also:general way, now be described as " an See also:area which is for the most See also:part set aside for the See also:production of See also:timber and other forest produce, or which is expected to exercise certain See also:climatic effects, or to protect the locality against injurious influences." As far. as conclusions can now be See also:drawn, it is probable that the greater part of the dry See also:land of the See also:earth was, at some See also:time, covered with forest, which consisted of a variety of trees and shrubs grouped according to See also:climate, See also:soil and configuration of the several localities . When the old trees reached their limit 2 Docum`nts Illustrative of See also:English Historyals . 338 . of See also:life, they disappeared, and younger trees took their place . The conditions for an uninterrupted regeneration of the forest were favourable, and the result was vigorous production by the creative See also:powers of soil and climate . Then came See also:man, and by degrees interfered, until in most countries of the earth the area under forest has been considerably reduced . The first decided interference was probably due to the See also:establishment of domestic animals; men burnt the forest to obtain pasture for their flocks . Subsequently similar See also:measures on an ever-increasing See also:scale were employed to prepare the land for agricultural purposes . More recently enormous areas of forests were destroyed by reckless cutting and subsequent firing in the extraction of timber for economic purposes . It will readily be understood that the See also:distribution and See also:character of the now remaining forests must differ enormously (see See also:PLANTS: Distribution) .

Large portions of the earth are still covered with dense masses of tall trees, while others contain See also:

low scrub or grass land, or are See also:desert . As a general See also:rule, natural forests consist of a number of different See also:species intermixed; but in some cases certain species, called gregarious, have succeeded in obtaining the upper See also:hand, thus forming more or less pure forests of one species only . The number of species differs very much . In many tropical forests hundreds of species may be found on a comparatively small area, in other cases the number is limited . See also:Burma has several thousand species of trees and shrubs, See also:Sind has only ten species of trees . Central See also:Europe has about See also:forty species, and the greater part of See also:northern See also:Russia, See also:Sweden and See also:Norway contains forests consisting of about See also:half a dozen species . See also:Elevation above the See also:sea acts similarly to rising See also:latitude, but the effect is much more rapidly produced . Generally speaking, it may be said that the Tropics and adjoining parts of the earth, wherever the climate is not modified by considerable elevation, contain broad-leaved species, palms, bamboos, &c . Here most of the best and hardest timbers are found, such as See also:teak, See also:mahogany and See also:ebony . The northern countries are See also:rich in conifers . Taking a See also:section from Central See also:Africa to See also:North Europe, it will be found that See also:south and north of the See also:equator there is a large See also:belt of dense hardwood forest; then comes the See also:Sahara, then the See also:coast of the Mediterranean with forests of See also:cork See also:oak; then See also:Italy with oak, See also:olive, See also:chestnut, gradually giving place to ash, sycamore, See also:beech, See also:birch and certain species of See also:pine; in See also:Switzerland and See also:Germany See also:silver See also:fir and spruce gain ground . Silver fir disappears in central Germany, and the countries around the Baltic contain forests consisting chiefly of Scotch pine, spruce and birch, to which, in See also:Siberia, See also:larch must be added, while the See also:lower parts of the ground are stocked with See also:hornbeam, See also:willow, See also:alder and See also:poplar .

In North See also:

America the distribution is as follows: Tropical vegetation is found in south See also:Florida, while in north Florida it changes into a subtropical vegetation consisting of See also:evergreen broad-leaved species with pines on sandy soils . On going north in the See also:Atlantic region, the forest becomes temperate, containing See also:deciduous broad-leaved trees and pines, until See also:Canada is reached, where larches, spruces and firs occupy the ground . Around the See also:great lakes on sandy soils the broad-leaved forest gives way to pines . On proceeding See also:west from the Atlantic region the forest changes into a shrubby vegetation, and this into the prairies . Farther west, towards the Pacific coast, extensive forests are found consisting, according to latitude and elevation above the sea, of pines, larches, fir, Thujas and Tsugas . In See also:Japan a tropical vegetation is found in the south, comprising palms, See also:figs, ebony, See also:mangrove and others . This is followed on proceeding north by subtropical forests containing evergreen oaks, Podocar pus, See also:tree-ferns, and, at higher elevations, See also:Cryptomeria and Chamaecyparis . Then follow deciduous broad-leaved forests, and finally firs, spruces and larches . In See also:India the character of the forests is governed chiefly by rainfall and elevation . Where the former is heavy evergreen forests of Guttiferae, Dipterocarpeae, See also:Leguminosae, Euphorbias, figs, palms, ferns, bamboos and india-See also:rubber trees are found . Under a less copious rainfall deciduous forests appear, containing teak and sal (Shored robusta) and a great variety of other valuable trees . Under a still .smaller rainfall the vegetation. becomes. sparse,containing acacias, Dalbergia sissoo and Tamarix .

Where the rainfall is very See also:

light or nil, desert appears . In the Himalayas, subtropical to See also:arctic conditions are found, the forests containing, according to elevation, pines, firs, deodars, oaks, chestnuts, magnolias, laurels, rhododendrons and bamboos . See also:Australia, again, has its own particular See also:flora of eucalypts, of which some two See also:hundred species have been distinguished, as well as wattles . Some of the eucalypts attain an enormous height . Utility of Forests.—In the See also:economy of man and of nature forests are of See also:direct and indirect value, the former chiefly through the produce which they yield, and the latter through the See also:influence which they exercise upon climate, the regulation of moisture, the stability of the soil, the healthiness and beauty of a See also:country and allied subjects . The indirect utility will be dealt with first . A piece of land See also:bare of vegetation is, throughout the See also:year, exposed to the full effect of See also:sun and See also:air currents, and the climatic conditions which are produced by these agencies . If, on the other hand, a piece of land is covered with a growth of plants, and especially with a dense See also:crop of forest vegetation; it enjoys the benefit of certain agencies which modify the effect of sun and See also:wind on the soil and the adjoining layers of air . These modifying agencies are as follows: (') The crowns of the trees intercept the rays of the sun and the falling See also:rain; they obstruct the See also:movement of air currents, and reduce See also:radiation at See also:night . (2) The leaves, See also:flowers and fruits, augmented by certain plants which grow in the shade of the trees, See also:form a layer of See also:mould, or humus, which protects the soil against rapid changes of temperature, and greatly influences the movement of See also:water in it . (3) The roots of the trees penetrate into the soil in all directions,' and bind it together . The effects of these agencies have been observed from See also:ancient times, and widely differing views have been taken of them .

Of See also:

late years, however, more careful observations have been made at so-called parallel stations, that is to say, one station in the See also:middle of a forest, and another outside at some distance from its edge, but otherwise exposed to the same general conditions . In this way, the following results have been obtained: (I) Forests reduce the temperature of the air and soil to a moderate extent, and render the climate more equable . (2) They increase the relative humidity of the air, and reduce evaporation . (3) They tend to increase the precipitation of moisture . As regards the actual rainfall, their effect in low lands is nil or very small; in hilly countries it is probably greater, but definite results have not yet been obtained owing to the difficulty of separating the effect of forests from that of other factors . (4) They help to regulate the water See also:supply, produce a more sustained feeding of springs, tend to reduce violent floods, and render the flow of water in See also:rivers more continuous . (5) They assist in preventing denudation, erosion, landslips; avalanches, the silting up of rivers and low lands and the formation of See also:sand See also:dunes . (6) They reduce the velocity of air-currents, protect adjoining See also:fields against See also:cold or dry winds, and afford shelter to See also:cattle, See also:game and useful birds . (q) They may, under certain conditions, improve the healthiness of a country, and help in its See also:defence . (8) They increase the beauty of a country, and produce a healthy aesthetic influence upon the people . The direct utility of forests is chiefly due to their produce, the See also:capital which they represent, and the See also:work which they See also:pro-vide . The See also:principal produce of forests consists of timber and firewood .

Both are necessaries for the daily life of the people . Apart from a limited number of broad-leaved species, the conifers have become the most'important timber trees in the economy of man . They are found in greatest quantities in the countries around the Baltic and in North America . In modern times See also:

iron and other materials have, to a considerable extent, replaced timber, while See also:coal, See also:lignite, and See also:peat compete with firewood; nevertheless See also:wood is still indispensable, and likely to remain so . This is See also:borne out by the See also:statistics of the most civilized nations . Whereas the See also:population of Great See also:Britain and See also:Ireland, during the See also:period 88o– See also:odd. increased by about 20%, the imports of timber, during the same period, increased by 45%; in other words; every See also:head of population in 'goo used more timber than twenty years earlier . Germany produced in 188o about as much timber as she required; in 1899 she imported 4,600,000 tons, valued at £14,000,000, and her imports are rapidly increasing, although the yield capacity of her own forests is much higher now than it was formerly . Wood is now used for many purposes which formerly were not thought of . The manufacture of the wood pulp annually imported into Britain consumes at least 2,000,000 tons of timber . - A fabric closely resembling See also:silk is now made of spruce wood . The variety of other, or See also:minor, produce yielded by forests is very great, and much of it is essential for the well-being of the people and for various See also:industries . The yield of See also:fodder is of the utmost importance in countries subject to periodic droughts; in many places See also:field crops could not be grown successfully without the See also:leaf-mould and brushwood taken from the forests .

As regards industries, See also:

attention need only be drawn to such articles as commercial fibre, tanning materials, dye-stuffs, See also:lac, See also:turpentine, See also:resin, rubber, See also:gutta-percha, &c . Great Britain and Ireland alone import every year such materials to the value of £12,000,000, half of this being represented by rubber . The capital employed in forests consists chiefly of the value of the soil and growing stock of timber . The latter is, ordinarily, of much greater value than the former wherever a sustained See also:annual yield of timber is expected from a forest . In the See also:case of a Scotch pine forest, for instance, the value of the growing stock is, under the above-mentioned See also:condition, from three to five times that of the soil . The See also:rate of See also:interest yielded by capital invested in forests differs, of course, considerably according to circumstances, but on the whole it may, under proper management, be placed equal to that yielded by agricultural land; it is lower than the agricultural rate on the better classes of land, but higher on the inferior classes . Hence the latter are specially indicated for the forest See also:industry, and the former for the production of agricultural crops . Forests require labour in a great variety of ways, such as (1) general See also:administration, formation, tending and harvesting; (2) transport of produce; and (3) industries which depend on forests for their See also:prime material . The labour indicated under the first head differs considerably according to circumstances, but its amount is smaller than that required if the land is used for See also:agriculture . Hence forests provide additional labour only if they are established on surplus lands . Owing to the bulky nature of forest produce its transport forms a business of considerable magnitude, the amount of labour being perhaps equal to half that employed under the first head . The greatest amount of labour is, however, required in the working up of the raw material yielded by forests .

In this respect attention may be drawn to the See also:

chair industry in and around High See also:Wycombe in See also:Buckinghamshire, where more than 20,000 workmen are employed in converting the beech, grown on the adjoining See also:chalk hills, into chairs and tools of many patterns . See also:Complete statistics for Great Britain are not available under this head, but it may be mentioned that in Germany the people employed in the forests amount to 2.3 % of the See also:total population; those employed on transport of forest produce 1.1 %; labourers employed on the various wood industries, 8-6 %; or a total of 12 % . An important feature of the work connected with forests and their produce is that a great part of it can be made to See also:fit in with the requirements of agriculture; that is to say, it can be done at seasons when field crops do not require attention . Thus the rural labourers or small farmers can See also:earn some See also:money at times when they have nothing else to do, and when they would probably sit idle if no forest work were obtainable . Whether, or how far, the utility of forests is brought out in a particular country depends on its See also:special conditions, such as (r) the position of a country, its communications, and the See also:control which it exercises over other countries, such as colonies; (2) the quantity and quality of substitutes for forest produce available in the country; (3) the value of land and labour, and the returns which land yields if used for other purposes; (4) the See also:density of population; (5) the amount of capital available for investment; (6)"-the climate and configuration; especiallythe See also:geographical position, whether inland or on the border of the sea, &c . No general rule can be laid down, showing whether forests are required in a country, or, if so, to what extent; that question must be answered according to the special circumstances of each case .

Russia, Sweden and Norway may as yet have more forest than they require for their own population . On the other hand, Great Britain and Ireland, Germany, Denmark, Portugal, Holland, and even Belgium, France and Italy have not a sufficient forest area to meet their own requirements; at the same time, they are all sea-See also:

bound countries, and importation is easy, while most of them are under the influence of moist sea winds, which reduces to a subordinate position the importance of forests for climatic reasons . Intimately connected with the area of forests in a country is the state of ownership—whether they belong to the state, corporations or to private persons . Where, apart from the See also:financial aspect and the supply of work, forests are not required for the See also:sake of their indirect effects, and where importation from other countries is easy and assured, the See also:government of the country need not, as a rule, trouble itself to maintain or acquire forests . Where the See also:reverse conditions exist, and especially where the cost of transport over See also:long distances becomes prohibitive, a See also:wise administration will take measures to assure the See also:maintenance of a suitable proportion of the country under forest . This can be done either by maintaining or constituting a suitable area of state forests, or by exercising a certain amount of control over See also:corporation and even private forests . Such measures are more called for in See also:continental countries than in those which are sea-bound, as is proved by the- above statistics . Supply of Timber — Imports and Exports.—The following table shows the See also:net imports and exports of European countries (See also:average data, calculated from the returns of See also:recent years) . The only timber-exporting countries of Europe are Russia, Sweden, Norway, Austria-Hungary and Rumania; all the others either have only enough for their own See also:consumption, or import timber . Great Britain and Ireland import now upwards of 20,000,000 tons a year, -Germany about 4,600,000 tons, and Belgium about 1,300,000 tons . Holland, France, Portugal, Spain and Italy are all importing countries, as also are See also:Asia Minor, See also:Egypt and See also:Algeria . The west coast of Africa exports hardwoods, and imports coniferous timber .

They consist chiefly of valuable hardwoods, like teak, mahogany, eucalypts and others . exports hardwoods and some Kauri pine from New See also:

Zealand, but imports larger quantities of light pine and fir timber . See also:British India and See also:Siam export teak and small quantities of See also:fancy See also:woods . The West Indies and South America export hardwoods, and import pine and fir wood . The United States of America will not much longer be a genuine exporting country, since they import already almost as much timber from Canada as they export . Canada exports considerable quantities of timber . The Dominion has still a forest area of 1,250,000 sq, m., equal to 38 % ',of the total area, and giving 165 acres of forest for every inhabitant . Although only about one-third of the forest area can be called See also:regular timber land, Canada possesses an enormous forest See also:wealth, with which she might supply permanently nearly all other countries deficient in material, if the governing bodies in the several provinces would only determine to stop the See also:present fearful See also:waste caused by See also:axe and See also:fire, and to introduce a regular See also:system of management . As matters stand, the supplies of the most valuable timber of Canada, the See also:white or See also:Weymouth pine (Pious strobus), arc nearly exhausted, the great stores of spruce in the eastern- provinces are being rapidly destroyed, and the forests of See also:Douglas fir in the western provinces have been attacked for export to the United States and to other countries . Taking the remaining See also:stocks of the whole earth together, it may be said that a sufficient quantity of hardwoods is available, but the only countries which are able to supply coniferous timber for export on a considerable scale are Russia, Sweden, Norway, Austria and Canada . As these countries have practically, to supply the rest of the See also:world, and as the management of their forests is far from satisfactory, the question of supplying light pine and fir timber, which forms the very See also:staff of life of the wood industries, must become a very serious See also:matter before many years have passed . Unmistakable signs of the coming crisis are every-where visible to all who wish to see, and it is difficult to over-state the gravity of the problem, when it is remembered, for instance, that 87 % of all the timber imported into Great Britain consists of light pine and fir, and that most of the other importing countries are similarly situated .

In some of these countries little or no See also:

room exists for the See also:extension of woodland, but this statement does not apply to Great Britain and Ireland, whichcontain upwards-of 12;000,000 acres of waste land, and s a, 500,00o acres of See also:mountain and See also:heath land used for light grazing . One-See also:fourth of that area, if put under forest, would produce all the timber now imported which can be. grown in Britain, that is to say, about 95 % of the total .

Forest Management.—In See also:early times there was practically no forest management . As long as the forests occupied considerable areas, their produce was looked upon as the See also:free See also:gift of nature, like air and water; men took it, used it, and even destroyed it without let or hindrance .

With the See also:

gradual increase of population and the consequent reduction of the forest area, proprietary ideas See also:developed; people claimed the ownership of certain forests, and proceeded to protect them against outsiders . Subsequently the See also:law of the country was called in to help in protection, leading to the promulgation of special forest See also:laws . By degrees it was found that See also:mere protection was not sufficient, and that steps must be taken to enforce a more judicious treatment,as well as to limit the removal of timber to what the forests were capablenf producing permanently . ' The teaching of natural See also:science and of See also:political economy was brought 'to See also:bear upon the subject, so that now forestry has become a special science . This is recognized in many countries, amongst which Germany stands first, closely followed by France, Austria, Denmark and Belgium . Of non-European countries the See also:palm belongs to British India, and then follow Ceylon, the See also:Malay States, the Cape of See also:Good See also:Hope and Japan . The United States of America have also turned their attention to the subject . Most of the British colonies are, in this respect, as yet in a backward state, and the matter has still to be fought out in Great Britain and Ireland, though many writers have urged the importance of the question upon the public and the government . There can be no doubt that all civilized countries must, sooner or later, adopt a rational and systematic treatment of their forests . For details as to the See also:separate countries, see the articles under the country headings; in this See also:article only some of the more important countries are dealt with, in so far as the See also:history of their forestry is important . A few notes on Germany and France will be given, because in these countries forest management has been brought to highest perfection; Italy is mentioned, because she has allowed her forests to be destroyed; and a See also:short description of forestry in the United Kingdom and in India follows . A separate section is devoted to the United States .

Germany is in general well-wooded . The winters being long and severe, an abundant supply of See also:

fuel is almost as essential as a sufficient supply of See also:food . This See also:necessity has led, along with a See also:passion for the chase, to the preservation of forests, and to the establishment of an admirable system of forest cultivation, almost as carefully conducted as field tillage . The See also:Black Forest stretches the whole length of the See also:grand-duchy of See also:Baden and part of the kingdom of Wtirttemberg, from the See also:Neckar to See also:Basel and the Lakeof See also:Constance . The vegetation resembles that of the See also:Vosges; forests of spruce, silver fir, Scotch pine, and, mingled with birches, beech and oak, are the See also:chief woods met with . Until comparatively recent times large quantities of timber derived from these forests were floated down the See also:Rhine to Holland and also shipped to See also:England . Now the greater part of it is used locally for construction, or it is converted into See also:paper pulp . In the grand-duchy of See also:Hesse the See also:Odenwald range of mountains, stretching between the See also:Main and the Neckar, contains the chief supply of timber . In the See also:province of See also:Nassau there are the large wooded tracts of the See also:Taunus mountain range and the Westerwald . In Rhenish See also:Prussia valuable forests See also:lie partly in the See also:Eifel, on the See also:borders of Belgium, and on the mountains overhanging the Upper Moselle, but they do not furnish such stately trees as the Black Forest and the Odenwald . The See also:Spessart, near See also:Aschaffenburg in See also:Bavaria, is one of the most extensive forests of middle Germany, containing large masses of See also:fine oak and beech, with plantations of coniferous trees, such as spruce, Scotch pine and silver fir . Bavaria possesses other fine forest tracts, such as the Baierischewald on the Bohemian frontier, the Kranzberg near See also:Munich, and the See also:Frankenwald in the north of the kingdom .

North Germany has extensive forests on the See also:

Hare and Thuringian Mountains, while in See also:East Prussia large tracts of See also:flat ground are covered with Scotch pine, spruce, oak and beech . Every See also:German state has its forest organization . In Prussia the See also:department is presided over by the Oberland Forstmeister at See also:Berlin, while each province, or part of a province, has an Oberforstmeister, under whom a number of OberfSrsters administrate the state and communal forests . These, again, are assisted by a lower class of officials called Forsters . The Oberforsters throughout Germany are educated at special See also:schools of forestry, of which in r9o9 the following nine existed: In Prussia: at See also:Eberswalde and Miinden . In Bavaria: at Munich and Aschaffenburg . In See also:Saxony: at Tharand . In See also:Wurttemberg: at See also:
