Dalbergia Cochinchinensis
''Dalbergia cochinchinensis'', the Thailand rosewood, Siamese rosewood, or tracwood, ( th, พะยูง: ''Phayung'' ; Vietnamese: Trắc (or Cẩm lai nam bộ); Khmer: ក្រញូង: ''Kranhung'' ; Lao: ກະຍູງ: ''Kayung'' ; Chinese: 酸枝木: ''Suān zhī mù'' ) is a species of legume in the family Fabaceae. It is a tree yielding valuable hardwood found in Cambodia, Laos, Thailand, and Vietnam. In 2022 its status was re-evaluated as Critically Endangered caused by illegal logging and smuggling. Conservationists project that the species could be extinct within 10 years (by 2026). Due to its pioneering characteristics, drought tolerance, and nitrogen-fixing ability, it shows potential for restoring degraded forests and deforested sites. Therefore, sustainable plantation of the tree can serve both goals of conservation and forest landscape restoration.

Jean Baptiste Louis Pierre
Jean Baptiste Louis Pierre (23 October 1833 – 30 October 1905), also known as J. B. Louis Pierre, was a French botanist known for his Asian studies. Early life Pierre was born in Saint-André, Réunion, and studied in Paris before working in the botanical gardens of Calcutta, India. Career In 1864 he founded the Saigon Zoo and Botanical Gardens, which he directed until 1877, after which he returned to Paris where he lived at 63 rue Monge, close to the Paris Herbarium. In 1883 he moved to Charenton, then to Villeneuve-Saint-Georges, then (circa 1893) to Saint-Mandé, and finally to 18 rue Cuvier in Paris, where he lived until his death. Pierre made many scientific explorations in tropical Asia. His publications include the ''Flore forestière de la Cochinchine'' (1880-1907), an article "Sur les plantes à caoutchouc de l'Indochine" (''Revue des cultures coloniales'', 1903) and the section on Sapotaceae in the ''Notes botaniques'' (1890-1891).

Dalbergia Oliveri
''Dalbergia oliveri'' is a species of legume in the family Fabaceae which grows in tree form to 15 – 30 meters in height (up to 100 ft.). The fruit is a green pod containing one to two seeds which turn brown to black when ripe. It is threatened by habitat loss and over-harvesting for its valuable red "rosewood" timber. University of Oxford published the transcriptomes of ''Dalbergia oliveri'' and five other ''Dalbergia'' spp. It was found that ''D. oliveri'' had more R genes than the co-occurring ''Dalbergia cochinchinensis''. Distribution naming and synonyms The trees are found in Myanmar, Thailand, Laos, Cambodia, and Vietnam. Common names in S.E. Asia are: Cambodian: "Neang Nuon", Thai: "Mai Ching Chan" (ไม้ชิงชัน), Laos: "Mai Kham Phii" (ໄມ້ຄຳພີ), Myanmar: "tamalan" (တမလန်း).

Convention On International Trade In Endangered Species
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working langu ...

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Furniture Industry
Furniture refers to movable objects intended to support various human activities such as seating (e.g., stools, chairs, and sofas), eating (tables), storing items, eating and/or working with an item, and sleeping (e.g., beds and hammocks). Furniture is also used to hold objects at a convenient height for work (as horizontal surfaces above the ground, such as tables and desks), or to store things (e.g., cupboards, shelves, and drawers). Furniture can be a product of design and can be considered a form of decorative art. In addition to furniture's functional role, it can serve a symbolic or religious purpose. It can be made from a vast multitude of materials, including metal, plastic, and wood. Furniture can be made using a variety of woodworking joints which often reflects the local culture. People have been using natural objects, such as tree stumps, rocks and moss, as furniture since the beginning of human civilization and continues today in some households/campsites. Ar ...

Wood Carving
Wood carving is a form of woodworking by means of a cutting tool (knife) in one hand or a chisel by two hands or with one hand on a chisel and one hand on a mallet, resulting in a wooden figure or figurine, or in the sculptural ornamentation of a wooden object. The phrase may also refer to the finished product, from individual sculptures to hand-worked mouldings composing part of a tracery. The making of sculpture in wood has been extremely widely practised, but doesn't survive undamaged as well as the other main materials like stone and bronze, as it is vulnerable to decay, insect damage, and fire. Therefore, it forms an important hidden element in the art history of many cultures. Outdoor wood sculptures do not last long in most parts of the world, so it is still unknown how the totem pole tradition developed. Many of the most important sculptures of China and Japan, in particular, are in wood, and so are the great majority of African sculpture and that of Oceania and ...

Phu Phan Mountains
The Phu Phan mountains ( th, ทิวเขาภูพาน, , ) are a range of hills dividing the Khorat Plateau of the Isan region of Thailand into two basins: the northern Sakhon Nakhon Basin, and the southern Khorat Basin. The silhouette of the Phu Phan Mountains appears in the provincial seal of Kalasin since they form the northern boundary of the province. The Phu Phan mountains are among the places in Thailand more severely affected by the Illegal logging of ''Phayung'' (Siamese Rosewood) trees. Although officially a protected tree, the cutting and trading of the endangered rosewood trees has been going unabated in Thailand's mountainous forested zones, even in the protected areas. In Thailand and in China this wood is highly valued in the furniture industry. Etymology The name of the range is derived from the characteristic Table (landform), tabletop shape of its peaks, for ''Phan (tray), phan'' is a kind of traditional tray on a pedestal.

Illegal Logging
Illegal logging is the harvest, transportation, purchase or sale of timber in violation of laws. The harvesting procedure itself may be illegal, including using corrupt means to gain access to forests; extraction without permission, or from a protected area; the cutting down of protected species; or the extraction of timber in excess of agreed limits. Illegal logging is a driving force for a number of environmental issues such as deforestation, soil erosion and biodiversity loss which can drive larger scale environmental crisis such as climate change and other forms of environmental degradation. Illegality may also occur during transport, such as illegal processing and export (through fraudulent declaration to customs); the avoidance of taxes and other charges, and fraudulent certification. These acts are often referred to as "wood laundering". Illegal logging is driven by a number of economic forces, such as demand for raw materials, land grabbing and demand for pasture for ...

Dowel
A dowel is a cylindrical rod, usually made of wood, plastic, or metal. In its original manufactured form, a dowel is called a ''dowel rod''. Dowel rods are often cut into short lengths called dowel pins. Dowels are commonly used as structural reinforcements in cabinet making and in numerous other applications, including: * Furniture shelf supports * Moveable game pieces (i.e. pegs) * Hangers for items such as clothing, key rings, and tools * Wheel axles in toys * Detents in gymnastics grips * Supports for tiered wedding cakes Wood dowel Manufacturing process The traditional tool for making dowels is a ''dowel plate'', an iron (or better, hardened tool steel) plate with a hole having the size of the desired dowel. To make a dowel, a piece of wood is split or whittled to a size slightly bigger than desired and then driven through the hole in the dowel plate. The sharp edges of the hole shear off the excess wood.Ivin SickelsExercises in Wood-Working American Book Company, 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joinery (woodworking)
Joinery is a part of woodworking that involves joining pieces of wood, engineered lumber, or synthetic substitutes (such as laminate), to produce more complex items. Some woodworking joints employ mechanical fasteners, bindings, or adhesives, while others use only wood elements (such as dowels or plain mortise and tenon fittings). The characteristics of wooden joints - strength, flexibility, toughness, appearance, etc. - derive from the properties of the materials involved and the purpose of the joint. Therefore, different joinery techniques are used to meet differing requirements. For example, the joinery used to construct a house can be different from that used to make cabinetry or furniture, although some concepts overlap. While a form of carpentry elsewhere, in British English usage it is distinguished from it, which is considered to be a form of structural timber work. History Many traditional wood joinery techniques use the distinctive material properties of wood, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
