Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic material – a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber.
Eucalyptus is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including Corymbia, they are commonly known as eucalypts. Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut".
Beech (Fagus) is a genus of deciduous trees in the family Fagaceae, native to temperate Europe, Asia and North America. Recent classifications recognize 10 to 13 species in two distinct subgenera, Engleriana and Fagus. The Engleriana subgenus is found only in East Asia, distinctive for their low branches, often made up of several major trunks with yellowish bark. The better known Fagus subgenus beeches are high-branching with tall, stout trunks and smooth silver-grey bark. The European beech is the most commonly cultivated.
Firewood is any wooden material that is gathered and used for fuel. Generally, firewood is not highly processed and is in some sort of recognizable log or branch form, compared to other forms of wood fuel like pellets or chips. Firewood can be seasoned and heat treated (dry) or unseasoned (fresh/wet). It is generally classified as hardwood or softwood.
Asado is the technique and the social event of having or attending a barbecue in various South American countries, especially Argentina, Chile and Uruguay where it is also a traditional event. An asado usually consists of beef, pork, chicken, chorizo, and morcilla which are cooked on a grill, called a parrilla, or an open fire. Generally the meats are accompanied by red wine and salads. This meat is prepared by a person who is the assigned asador or parrillero.
Yohimbine, also known as quebrachine, is an indole alkaloid derived from the bark of the African tree Pausinystalia johimbe; also from the bark of the unrelated South American tree Aspidosperma quebracho-blanco. Yohimbine is an α2-adrenergic receptor antagonist, and has been used in a variety of research projects. It is a veterinary drug used to reverse sedation in dogs and deer.
The Gran Chaco or Dry Chaco is a sparsely populated, hot and semiarid lowland natural region of the Río de la Plata basin, divided among eastern Bolivia, western Paraguay, northern Argentina, and a portion of the Brazilian states of Mato Grosso and Mato Grosso do Sul, where it is connected with the Pantanal region. This land is sometimes called the Chaco Plain.
Betula papyrifera is a short-lived species of birch native to northern North America. Paper birch is named for the tree's thin white bark, which often peels in paper like layers from the trunk. Paper birch is often one of the first species to colonize a burned area within the northern latitudes, and is an important species for moose browsing. The wood is often used for pulpwood and firewood.
The Chaco National Park is a national park of Argentina, located in the province of Chaco. It has an area of 150 km2. It was created in 1954 in order to protect a sample of the Eastern Chaco, composed mainly of warm lowlands, with an annual summer rainfall between 750 and 1,300 mm.
Copo National Park is a federal protected area in Santiago del Estero Province, Argentina. Established on 22 November 2000, it houses a representative sample of the Dry Chaco biodiversity in average state of conservation. Located in the Copo Department, it has an area of 118,118 ha.
Schinopsis lorentzii is a hardwood tree known as red quebracho, native of the Paraguayan subtropical area, which forms forests in Gran Chaco region of Argentina, in Paraguay, and Bolivia. Some of its common names are coronillo, quebracho Cornillo (Brazil), quebracho chaqueño, quebracho colorado santiagueño, quebracho macho, and quebracho bolí. The qualification colorado ("red") differentiates it from other species of common quebracho tree, the Aspidosperma quebracho-blanco. The indication santiagueño is made to distinguish it from quebracho colorado chaqueño, a closely related species.
Prosopis alba is a South American tree species that grows in central Argentina, the Gran Chaco ecoregion, and part of the Argentine Mesopotamia, as well as Bolivia, Paraguay, and Peru. It is known as algarrobo blanco in Spanish. Spanish settlers gave it that name because of its similarity to the European carob tree. Other common names come from Guaraní, including ibopé and igopé.
Schinopsis is a genus of South American trees in the family Anacardiaceae, also known by the common names quebracho, quebracho colorado and red quebracho. In Brazil it is known as baraúna or braúna.
The Humid Chaco is tropical grasslands, savannas, and shrublands ecoregion in South America. It lies in the basin of the Paraná River, covering portions of central Paraguay and northern Argentina, and with a small portion of southwestern Brazil and northwestern Uruguay. The natural vegetation is a mosaic of grasslands, palm savanna, and forest.
Schinopsis balansae is a hardwood tree known as willow-leaf red quebracho which forms forests in the subtropical Gran Chaco ecoregion of north-eastern Argentina, and Paraguay. It is also found in the wild Pantanal vegetation in Brazil. Some of its vernacular names are quebracho colorado chaqueño and quebracho santafesino. Other species, like Schinopsis lorentzii, bear the general name quebracho and have similar properties and uses. S. balansae shares its habitat with a species of the same genus, S. heterophylla, and the two are often confused.
Geoffroea decorticans, the chañar, kumbaru, or Chilean palo verde, is a small deciduous tree, up to 8 meters (25 ft) tall that inhabits most arid forests of southern South America. The chañar is cold and drought deciduous; it loses its leaves in winter, and possibly in summer if conditions get too dry. It is natural to Bolivia, Chile, Argentina, also present in Paraguay and southern Peru. It is a very characteristic tree in local culture and folk because of its vivid visual presence, propagation, and ancient ethnomedical uses.
The forestry sector in Argentina has great potential. The geography of the country extends from north to south, encompassing 4,000 kilometres (2,500 mi). Its variety of climates, land quality, and reliable precipitation allow for the cultivation of different tree species at high growth rates. The climate varies and most areas are quite temperate. The country also enjoys short harvest periods for the most important species. This has allowed the industry to become more competitive and continue its high growth rates.
Quebracho is a common name in Spanish to describe very hard wood tree species. The etymology of the name derived from quiebrahacha, or quebrar hacha, meaning "axe-breaker".
Quebracho Herrado is a small community in San Justo Department of Córdoba Province, Argentina. It was the location of the famous Battle of Quebracho Herrado in 1840 during the civil wars. The town has about 317 inhabitants. It is about 238 kilometres (148 mi) from the city of Córdoba
