Galicia is an autonomous community of Spain and historic nationality under Spanish law. Located in the north-west of the Iberian Peninsula, it comprises the provinces of A Coruña, Lugo and Pontevedra, being bordered by Portugal to the south, the Spanish autonomous communities of Castile and León and Asturias to the east, the Atlantic Ocean to the west, the Cantabrian Sea to the north, it had a population of 2,718,525 in 2016 and has a total area of 29,574 km2. Galicia has over 1,660 km of coastline, including its offshore islands and islets, among them Cíes Islands, Ons, Sálvora, and—the largest and most populated—A Illa de Arousa; the area now called Galicia was first inhabited by humans during the Middle Paleolithic period, it takes its name from the Gallaeci, the Celtic people living north of the Douro River during the last millennium BC, in a region coincidental with that of the Iron Age local Castro culture. Galicia was incorporated into the Roman Empire at the end of the Cantabrian Wars in 19 BC, was made a Roman province in the 3rd century AD.
In 410, the Germanic Suebi established a kingdom with its capital in Braga. In 711, the Islamic Umayyad Caliphate invaded the Iberian Peninsula conquering the Visigoth kingdom of Hispania by 718, but soon Galicia was incorporated into the Christian kingdom of Asturias by 740. During the Middle Ages, the kingdom of Galicia was ruled by its own kings, but most of the time it was leagued to the kingdom of Leon and to that of Castile, while maintaining its own legal and customary practices and culture. From the 13th century on, the kings of Castile, as kings of Galicia, appointed an Adiantado-mór, whose attributions passed to the Governor and Captain General of the Kingdom of Galiza from the last years of the 15th century; the Governor presided the Real Audiencia do Reino de Galicia, a royal tribunal and government body. From the 16th century, the representation and voice of the kingdom was held by an assembly of deputies and representatives of the cities of the kingdom, the Cortes or Junta of the Kingdom of Galicia.
This institution was forcibly discontinued in 1833 when the kingdom was divided into four administrative provinces with no legal mutual links. During the 19th and 20th centuries, demand grew for self-government and for the recognition of the culture of Galicia; this resulted in the Statute of Autonomy of 1936, soon frustrated by Franco's coup d'etat and subsequent long dictatorship. After democracy was restored the legislature passed the Statute of Autonomy of 1981, approved in referendum and in force, providing Galicia with self-government; the interior of Galicia is characterized by a hilly landscape. The coastal areas are an alternate series of rías and cliffs; the climate of Galicia is temperate and rainy, with markedly drier summers. Its topographic and climatic conditions have made animal husbandry and farming the primary source of Galicia's wealth for most of its history, allowing for a relative high density of population. With the exception of shipbuilding and food processing, Galicia was based on a farming and fishing economy until after the mid-20th century, when it began to industrialize.
In 2012, the gross domestic product at purchasing power parity was €56,000 million, with a nominal GDP per capita of €20,700. The population is concentrated in two main areas: from Ferrol to A Coruña in the northern coast, in the Rías Baixas region in the southwest, including the cities of Vigo and the interior city of Santiago de Compostela. There are smaller populations around the interior cities of Ourense; the political capital is Santiago de Compostela, in the province of A Coruña. Vigo, in the province of Pontevedra, is the most populous municipality, with 292,817, while A Coruña is the most populous city, with 215,227. Two languages are official and used today in Galicia: Galician and Spanish. Galician is a Romance language related to Portuguese, with which it shares Galician-Portuguese medieval literature, Spanish, sometimes referred to as Castilian, used throughout the country. Spanish is spoken fluently by all in Galicia, in 2013 it was reported that 51% of the Galician population used more Galician on a day-to-day, 48% used more Spanish.
The name Galicia derives from the Latin toponym Callaecia Gallaecia, related to the name of an ancient Celtic tribe that resided north of the Douro river, the Gallaeci or Callaeci in Latin, or Καλλαϊκoί in Greek. These Callaeci were the first tribe in the area to help the Lusitanians against the invading Romans; the Romans applied their name to all the other tribes in the northwest who spoke the same language and lived the same life. The etymology of the name has been studied since the 7th century by authors such as Isidore of Seville, who wrote that "Galicians are called so, because of their fair skin, as the Gauls", relating the name to the Greek word for milk. In the 21st century, some scholars have derived the name of the ancient Callaeci either from Proto-Indo-European *kal-n-eH2'hill', through a local relational suffix -aik-, so meaning'the hill'. In any case, being per se a derivation of the ethnic name Kallaikói, means'the land of the Galicians'; the most recent proposal comes from linguist Francesco Benozzo afte
Beech is a genus of deciduous trees in the family Fagaceae, native to temperate Europe and North America. Recent classification systems of the genus recognize 10 to 13 species in two distinct subgenera and Fagus; the Engleriana subgenus is found only in East Asia, is notably distinct from the Fagus subgenus in that these beeches are low-branching trees made up of several major trunks with yellowish bark. Further differentiating characteristics include the whitish bloom on the underside of the leaves, the visible tertiary leaf veins, a long, smooth cupule-peduncle. Fagus japonica, Fagus engleriana, the species F. okamotoi, proposed by the botanist Chung-Fu Shen in 1992, comprise this subgenus. The better known Fagus subgenus beeches are high-branching with tall, stout trunks and smooth silver-grey bark; this group includes Fagus sylvatica, Fagus grandifolia, Fagus crenata, Fagus lucida, Fagus longipetiolata, Fagus hayatae. The classification of the European beech, Fagus sylvatica is complex, with a variety of different names proposed for different species and subspecies within this region.
Research suggests that beeches in Eurasia differentiated late in evolutionary history, during the Miocene. The populations in this area represent a range of overlapping morphotypes, though genetic analysis does not support separate species. Within its family, the Fagaceae, recent research has suggested that Fagus is the evolutionarily most basal group; the southern beeches thought related to beeches, are now treated as members of a separate family, the Nothofagaceae. They are found in Australia, New Zealand, New Guinea, New Caledonia and Chile; the European beech is the most cultivated, although few important differences are seen between species aside from detail elements such as leaf shape. The leaves of beech trees are entire or sparsely toothed, from 5 -- 4 -- 10 cm broad. Beeches are monoecious; the small flowers are unisexual, the female flowers borne in pairs, the male flowers wind-pollinating catkins. They are produced in spring; the bark is light grey. The fruit is a small three–angled nut 10–15 mm long, borne singly or in pairs in soft-spined husks 1.5–2.5 cm long, known as cupules.
The husk can have a variety of spine- to scale-like appendages, the character of which is, in addition to leaf shape, one of the primary ways beeches are differentiated. The nuts are edible, though bitter with a high tannin content, are called beechnuts or beechmast; the name of the tree is of Indo-European origin, played an important role in early debates on the geographical origins of the Indo-European people. Greek φηγός is from the same root, but the word was transferred to the oak tree as a result of the absence of beech trees in Greece. Beech grows on a wide range of soil types, provided they are not waterlogged; the tree canopy casts dense shade, carpets the ground thickly with leaf litter. In North America, they form beech-maple climax forests by partnering with the sugar maple; the beech blight aphid is a common pest of American beech trees. Beeches are used as food plants by some species of Lepidoptera. Beech bark is thin and scars easily. Since the beech tree has such delicate bark, such as lovers' initials and other forms of graffiti, remain because the tree is unable to heal itself.
Beech bark disease is a fungal infection that attacks the American beech through damage caused by scale insects. Infection can lead to the death of the tree. Fagus sylvatica was a late entrant to Great Britain after the last glaciation, may have been restricted to basic soils in the south of England; some suggest. The beech is classified as a native in the south of England and as a non-native in the north where it is removed from'native' woods. Large areas of the Chilterns are covered with beech woods, which are habitat to the common bluebell and other flora; the Cwm Clydach National Nature Reserve in southeast Wales was designated for its beech woodlands, which are believed to be on the western edge of their natural range in this steep limestone gorge. Beech is not native to Ireland; the Friends of the Irish Environment say that the best policy is to remove young regenerating beech, while retaining veteran specimens with biodiversity value. A campaign by Friends of the Rusland Beeches and South Lakeland Friends of the Earth launched in 2007 to reclassify the beech as native in Cumbria.
The campaign is backed by Tim Farron, MP, who tabled a motion on 3 December 2007 regarding the status of beech in Cumbria. Today, beech is planted for hedging and in deciduous woodlands, mature, regenerating stands occur throughout mainland Britain below about 650 m; the tallest and longest hedge in the world is the Meikleour Beech Hedge in Meikleour and Kinross, Scotland. The common European beech grows in Denmark and southern Norway and Sweden up to about the 57–59°N; the most northern known growing beech trees are found in a few small forests around the city of Bergen on th
Basque Country (autonomous community)
The Basque Country the Basque Autonomous Community is an autonomous community in northern Spain. It includes the Basque provinces of Álava and Gipuzkoa; the Basque Country or Basque Autonomous Community was granted the status of nationality within Spain, attributed by the Spanish Constitution of 1978. The autonomous community is based on the Statute of Autonomy of the Basque Country, a foundational legal document providing the framework for the development of the Basque people on Spanish soil. Navarre, which had narrowly rejected a joint statue of autonomy with Gipuzkoa, Álava and Biscay in 1932, was granted a separate statute in 1982. There is no official capital in the autonomous community, but the city of Vitoria-Gasteiz, in the province of Álava, is the de facto capital as the location of the Basque Parliament, the headquarters of the Basque Government, the residence of the President of the Basque Autonomous Community; the High Court of Justice of the Basque Country has its headquarters in the city of Bilbao.
Whilst Vitoria-Gasteiz is the largest municipality in area, with 277 km2, Bilbao is the largest in population, with 353,187 people, located in the province of Biscay within a conurbation of 875,552 people. The term Basque Country may refer to the larger cultural region, the home of the Basque people, which includes the autonomous community; the following provinces make up the autonomous community: Álava, capital Vitoria-Gasteiz Biscay, capital Bilbao-Bilbo Gipuzkoa, capital Donostia-San Sebastián The Basque Country borders Cantabria and the Burgos province to the west, the Bay of Biscay to the north and Navarre to the east and La Rioja to the south. The territory has three distinct areas, which are defined by the two parallel ranges of the Basque Mountains; the main range of mountains forms the watershed between the Mediterranean basins. The highest point of the range is in the Aizkorri massif; the three areas are: Formed by many valleys with short rivers that flow from the mountains to the Bay of Biscay, like the Nervión, Urola or Oria.
The coast is rough, with small inlets. The main features of the coast are the Bilbao Abra Bay and the Estuary of Bilbao, the Urdaibai estuary and the Bidasoa-Txingudi Bay that forms the border with France. Between the two mountain ranges, the area is occupied by a high plateau called Llanada Alavesa, where the capital Vitoria-Gasteiz is located; the rivers flow south from the mountains to the Ebro River. The main rivers are the Zadorra Bayas River. From the southern mountains to the Ebro is the so-called Rioja Alavesa, which shares the Mediterranean characteristics of other Ebro Valley zones; some of Spain's production of Rioja wine takes place here. The Basque Mountains form the watershed and mark the distinct climatic areas of the Basque Country: The northern valleys, in Biscay and Gipuzkoa and the valley of Ayala in Álava, are part of Green Spain, where the oceanic climate is predominant, with its wet weather all year round and moderate temperatures. Precipitation average is about 1200 mm; the middle section is influenced more by the continental climate, but with a varying degree of the northern oceanic climate.
This gives cold, snowy winters. The Ebro valley has a pure continental climate: winters are cold and dry and summers warm and dry, with precipitation peaking in spring and autumn. Precipitation is irregular, as low as 300 mm. Half of the 2,155,546 inhabitants of the Basque Autonomous Community live in Greater Bilbao, Bilbao's metropolitan area. Of the ten most populous cities, six form part of Bilbao's conurbation, known as Greater Bilbao. With 28.2% of the Basque population born outside this region, immigration is crucial to Basque demographics. Over the 20th century most of this immigration came from other parts of Spain from Galicia or Castile and León. Over recent years, sizeable numbers of this population have returned to their birthplaces and most immigration to the Basque country now comes from abroad, chiefly from South America. Roman Catholicism is, by far, the largest religion in the Basque Country. In 2012, the proportion of Basques that identified themselves as Roman Catholic was 58.6%, while it is one of the most secularised communities of Spain: 24.6% were non-religious and 12.3% of Basques were atheist.
Bilbao-Bilbo Vitoria-Gasteiz San Sebastián-Donostia Barakaldo Getxo Irun Portugalete Santurtzi Basauri Errenteria Spanish and Basque are co-official in all territories of the autonomous community. The Basque-speaking areas in the modern-day autonomous community are set against the wider context of the Basque language, spoken to the east in Navarre and the French Basque Country; the whole Basque speaking territory has experienced both expansion in its history. The Basque language experienced a gradual territorial contraction throughout the last nine centuries, severe deterioration of its sociolinguistic status for much of the 20th century due to heavy immigration from other parts of Spain, the virtual nonexistence of Basque language schooling, national policies implemented by the different Spanish régimes. After the advent of the Statute of Autonomy of the Basque Countr
An oceanic climate known as a marine climate or maritime climate, is the Köppen classification of climate typical of west coasts in higher middle latitudes of continents, features mild summers and mild winters, with a narrow annual temperature range and few extremes of temperature, with the exception for transitional areas to continental and highland climates. Oceanic climates are defined as having a monthly mean temperature below 22 °C in the warmest month, above 0 °C in the coldest month, it lacks a dry season, as precipitation is more evenly dispersed throughout the year. It is the predominant climate type across much of Western Europe including the United Kingdom, the Pacific Northwest region of the United States and Canada, portions of central Mexico, southwestern South America, southeastern Australia including Tasmania, New Zealand, as well as isolated locations elsewhere. Oceanic climates are characterised by a narrower annual range of temperatures than in other places at a comparable latitude, do not have the dry summers of Mediterranean climates or the hot summers of humid subtropical.
Oceanic climates are most dominant in Europe, where they spread much farther inland than in other continents. Oceanic climates can have considerable storm activity as they are located in the belt of the stormy westerlies. Many oceanic climates have frequent cloudy or overcast conditions due to the near constant storms and lows tracking over or near them; the annual range of temperatures is smaller than typical climates at these latitudes due to the constant stable marine air masses that pass through oceanic climates, which lack both warm and cool fronts. Locations with oceanic climates tend to feature cloudy conditions with precipitation, though it can experience clear, sunny days. London is an example of an oceanic climate, it experiences constant precipitation throughout the entire year. Despite this, thunderstorms are quite rare since hot and cold air masses meet infrequently in the region. In most areas with an oceanic climate, precipitation comes in the form of rain for the majority of the year.
However, some areas with this climate see some snowfall annually during winter. Most oceanic climate zones, or at least a part of them, experience at least one snowfall per year. In the poleward locations of the oceanic climate zone, snowfall is more commonplace. Overall temperature characteristics of the oceanic climates feature cool temperatures and infrequent extremes of temperature. In the Köppen climate classification, Oceanic climates have a mean temperature of 0 °C or higher in the coldest month, compared to continental climates where the coldest month has a mean temperature of below 0 °C. Summers are cool, with the warmest month having a mean temperature below 22 °C. Poleward of the latter is a zone of the aforementioned subpolar oceanic climate, with long but mild winters and cool and short summers. Examples of this climate include parts of coastal Iceland, Norway, the Scottish Highlands, the mountains of Vancouver Island, Haida Gwaii in Canada, in the Northern Hemisphere and extreme southern Chile and Argentina in the Southern Hemisphere, the Tasmanian Central Highlands, parts of New Zealand.
Oceanic climates are not always found in coastal locations on the aforementioned parallels. The polar jet stream, which moves in a west to east direction across the middle latitudes, advances low pressure systems and fronts. In coastal areas of the higher middle latitudes, the prevailing onshore flow creates the basic structure of most oceanic climates. Oceanic climates are a reflection of the ocean adjacent to them. In the fall and early spring, when the polar jet stream is most active, the frequent passing of marine weather systems creates the frequent fog, cloudy skies, light drizzle associated with oceanic climates. In summer, high pressure pushes the prevailing westerlies north of many oceanic climates creating a drier summer climate; the North Atlantic Gulf Stream, a tropical oceanic current that passes north of the Caribbean and up the East Coast of the United States to North Carolina heads east-northeast to the Azores, is thought to modify the climate of Northwest Europe. As a result of the Gulf Stream, west-coast areas located in high latitudes like Ireland, the UK, Norway have much milder winters than would otherwise be the case.
The lowland attributes of western Europe help drive marine air masses into continental areas, enabling cities such as Dresden and Vienna to have maritime climates in spite of being located well inland from the ocean. Oceanic climates in Europe occur in Northwest Europe, from Ireland and Great Britain eastward to central Europe. Most of France, the Netherlands, Germany, the north coast of Spain, the western Azores off the coast of Portugal, the south of Kosovo and southern portions of Sweden have oceanic climates. Examples of oceanic climates are found in Glasgow, Bergen, Dublin, Bilbao, Donostia-San Sebastian, Bayonne, Züri
Asturias the Principality of Asturias, is an autonomous community in north-west Spain. It is coextensive with the province of Asturias, contains some of the territory, part of the larger Kingdom of Asturias in the Middle Ages. Divided into eight comarcas, the autonomous community of Asturias is bordered by Cantabria to the east, by Castile and León to the south, by Galicia to the west, by the Bay of Biscay to the north; the most important cities are the communal capital, the seaport and largest city Gijón, the industrial town of Avilés. Other municipalities in Asturias include Cangas de Onís, Cangas del Narcea, Gozón, Langreo, Laviana, Llanes, Siero, Valdés, Vegadeo and Villaviciosa. Asturias is home of the Princess of Asturias Awards. Asturias was inhabited, first by Homo erectus by Neanderthals. Since the Lower Paleolithic era, during the Upper Paleolithic, Asturias was characterized by cave paintings in the eastern part of the area. In the Mesolithic period, a native culture developed, that of the Asturiense, with the introduction of the Bronze Age and tumuli were constructed.
In the Iron Age, the territory came under the cultural influence of the Celts. Today the Astur Celtic influence persists in place names, such as those of mountains. With the conquest of Asturias by the Romans under Augustus, the region entered into recorded history; the Astures were subdued by the Romans but were never conquered. After several centuries without foreign presence, they enjoyed a brief revival during the Germanic invasions of the late 4th century AD, resisting Suevi and Visigoth raids throughout the 5th Century AD, ending with the Moorish invasion of Spain. However, as it had been for the Romans and Visigoths, the Moors did not find mountainous territory easy to conquer, the lands along Spain's northern coast never became part of Islamic Spain. Rather, with the beginning of the Moorish conquest in the 8th century, this region became a refuge for Christian nobles, in 722, a de facto independent kingdom was established, the Regnum Asturorum, to become the cradle of the incipient Reconquista.
In the 10th century, the Kingdom of Asturias gave way to the Kingdom of León, during the Middle Ages the geographic isolation of the territory made historical references scarce. Through the rebellion of Henry II of Castile in the 14th century, the Principality of Asturias was established; the most famous proponents of independence were Gonzalo Peláez and Queen Urraca, while achieving significant victories, were defeated by Castilian troops. After its integration into the Kingdom of Spain, Asturias provided the Spanish court with high-ranking aristocrats and played an important role in the colonisation of America. Since 1388, the heir to the Castilian throne has been styled Prince of Asturias. In the 16th century, the population reached 100,000 for the first time, within another century that number would double due to the arrival of American corn. In the 18th century, Asturias was one of the centres of the Spanish Enlightenment; the renowned Galician thinker Benito de Feijóo settled in the Benedictine Monastery of San Vicente de Oviedo.
Gaspar Melchor de Jovellanos, a polymath and prominent reformer and politician of the late 18th century, was born in the seaside town of Gijón. During the Napoleonic Wars, Asturias was the first Spanish province to rise up against the French following the abdication of King Ferdinand VII on 10 May 1808. Riots began in Oviedo and on 25 May the local government formally declared war on Napoleon with 18,000 men called to arms to resist invasion; the Industrial Revolution came to Asturias after 1830 with the discovery and systematic exploitation of coal mines and iron factories at the mining basins of Nalón and Caudal. At the same time, there was significant migration to the Americas; these entrepreneurs were known collectively as'Indianos', for having visited and made their fortunes in the West Indies and beyond. The heritage of these wealthy families can still be seen in Asturias today: many large'modernista' villas are dotted across the region, as well as cultural institutions such as free schools and public libraries.
Asturias played an important part in the events. In October 1934 Asturian miners and other workers staged an armed uprising to oppose the coming to power of the right-wing CEDA party, which had obtained three ministerial posts in the centralist government of the Second Spanish Republic. For a month, a Popular Front Committee exercised control in southern Asturias, while local workers committees sprang up elsewhere in the region. A war committee dominated by anarcho-syndicalist supporters took power in Oviedo. Troops under the command of a unknown general named Francisco Franco Bahamonde were brought from Spanish Morocco to suppress the revolt. Franco applied tactics reserved for overseas colonies, using troops of the Spanish Legion and Moroccan troops: ferocious oppression followed; as a result, Asturias remained loyal to the republican governme
Pulp and paper industry
The pulp and paper industry comprises companies that use wood as raw material and produce pulp, paper and other cellulose-based products. The pulp is fed to a paper machine where it is formed as a paper web and the water is removed from it by pressing and drying. Pressing the sheet removes the water by force. Once the water is forced from the sheet, a special kind of felt, not to be confused with the traditional one, is used to collect the water. Whereas, when making paper by hand, a blotter sheet is used instead. Drying involves using heat to remove water from the paper sheets. In the earliest days of paper making, this was done by hanging the sheets like laundry. In more modern times, various forms of heated drying mechanisms are used. On the paper machine, the most common is the steam heated can dryer; the commercial planting of domesticated mulberry trees to make pulp for papermaking is attested as early as the 6th century. Due to advances in printing technology, the Chinese paper industry continued to grow under the Song dynasty to meet the rising demand for printed books.
Demand for paper was stimulated by the Song government, which needed a large supply of paper for printing paper money and exchange certificates. The first mechanised paper machine was installed at Frogmore Paper Mill, Hertfordshire in 1803, followed by another in 1804; the site operates as a museum. The pulp and paper industry has been criticized by environmental groups like the Natural Resources Defense Council for unsustainable deforestation and clearcutting of old-growth forest; the industry trend is to expand globally to countries like Russia and Indonesia with low wages and low environmental oversight. According to Greenpeace, farmers in Central America illegally rip up vast tracts of native forest for cattle and soybean production without any consequences, companies who buy timber from private land owners contribute to massive deforestation of the Amazon Rainforest. On the other hand, the situation is quite different where forest growth has been on the increase for a number of years, it is estimated for instance that since 1990 forests have grown in Europe by a size equivalent to that of Switzerland, supported through the practice of sustainable forest management by the industry.
In Sweden, for every tree, felled, two are planted. The industry is dominated by northern European and East Asian countries. Australasia and Brazil have significant pulp and paper enterprises; the industry has a significant presence in a number of European countries including Germany, Italy, the Netherlands and Poland. The United States had been the world's leading producer of paper until it was overtaken by China in 2009. According to statistic data by RISI, main producing countries of paper and paperboard, not including pulp, in the world are as follows: The world's main paper and paperboard company groups are as follows.: In 2008, the top 10 forest and packaging products companies were, according to a report by PricewaterhouseCoopers: Leading manufacturers of capital equipment with over $1 billion in annual revenue for the pulp and paper industry include: Valmet Bellmer Andritz Metso Voith Kadant American Forest & Paper Association List of paper mills Converters Paper pollution Pulp and Paper Pulp and paper industry in Canada Pulp and paper industry in Europe Confederation of European Paper Industries Pulp and paper industry in Japan Pulp and paper industry in the United States Roll hardness tester Wood industry Forestry industry Environmental impact of paper Confederation of European Paper Industries American Forest & Paper Association Forest Products Association of Canada
A plantation is the large-scale estate meant for farming that specializes in cash crops. The crops that are grown include cotton, tea, sugar cane, oil seeds, oil palms, rubber trees, fruits. Protectionist policies and natural comparative advantage have sometimes contributed to determining where plantations were located. A plantation house is the main house of a plantation a substantial farmhouse, which serves as a symbol for the plantation as a whole. Plantation houses in the Southern United States and in other areas are known as quite grand and expensive architectural works today, though most were more utilitarian, working farmhouses. Among the earliest examples of plantations were the latifundia of the Roman Empire, which produced large quantities of wine and olive oil for export. Plantation agriculture grew with the increase in international trade and the development of a worldwide economy that followed the expansion of European colonial empires. Like every economic activity, it has changed over time.
Industrial plantations are established to produce a high volume of wood in a short period of time. Plantations are grown by state forestry authorities and/or the paper and wood industries and other private landowners. Christmas trees are grown on plantations as well. In southern and southeastern Asia, teak plantations have replaced the natural forest. Industrial plantations are managed for the commercial production of forest products. Industrial plantations are large-scale. Individual blocks are even-aged and consist of just one or two species; these species can be indigenous. The plants used for the plantation are genetically altered for desired traits such as growth and resistance to pests and diseases in general and specific traits, for example in the case of timber species, volumic wood production and stem straightness. Forest genetic resources are the basis for genetic alteration. Selected individuals grown in seed orchards are a good source for seeds to develop adequate planting material. Wood production on a tree plantation is higher than that of natural forests.
While forests managed for wood production yield between 1 and 3 cubic meters per hectare per year, plantations of fast-growing species yield between 20 and 30 cubic meters or more per hectare annually. In 2000, while plantations accounted for 5% of global forest, it is estimated that they supplied about 35% of the world's roundwood. In the first year, the ground is prepared by the combination of burning, herbicide spraying, and/or cultivation and saplings are planted by human crew or by machine; the saplings are obtained in bulk from industrial nurseries, which may specialize in selective breeding in order to produce fast growing disease- and pest-resistant strains. In the first few years until the canopy closes, the saplings are looked after, may be dusted or sprayed with fertilizers or pesticides until established. After the canopy closes, with the tree crowns touching each other, the plantation is becoming dense and crowded, tree growth is slowing due to competition; this stage is termed'pole stage'.
When competition becomes too intense, it is time to thin out the section. There are several methods for thinning, but where topography permits, the most popular is'row-thinning', where every third or fourth or fifth row of trees is removed with a harvester. Many trees are removed, leaving regular clear lanes through the section so that the remaining trees have room to expand again; the removed trees are delimbed, forwarded to the forest road, loaded onto trucks, sent to a mill. A typical pole stage plantation tree is 7–30 cm in diameter at breast height; such trees are sometimes not suitable for timber, but are used as pulp for paper and particleboard, as chips for oriented strand board. As the trees grow and become dense and crowded again, the thinning process is repeated. Depending on growth rate and species, trees at this age may be large enough for timber milling. Around year 10-60 the plantation is falling off the back side of its growth curve; that is to say, it is passing the point of maximum wood growth per hectare per year, so is ready for the final harvest.
All remaining trees are felled and taken to be processed. The ground is cleared, the cycle can be restarted; some plantation trees, such as pines and eucalyptus, can be at high risk of fire damage because their leaf oils and resins are flammable to the point of a tree being explosive under some conditions. Conversely, an afflicted plantation can in some cases be cleared of pest species cheaply through the use of a prescribed burn, which kills all lesser plants but does not harm the mature trees. Many forestry experts claim that the establishment of plantations will reduce or eliminate the need to exploit natural forest for wood production. In principle this is true. Many point to the example of New Zealand, where 19% of the forest area provides 99% of the supply of industrial round wood, it has been estimated that the world's demand for fiber could be met by just 5% of the world fores
