Cedrela Angustifolia
''Cedrela angustifolia'' is a species of tree in the mahogany family, Meliaceae. Local common names include ''cedro de Tucumán'', ''cedro bayo'', ''cedro coya'', and ''cedro del cerro''. It is native to South America, where it occurs in Argentina, Bolivia and Peru. This is a species of mountain forests. It easily colonizes disturbed habitat, forming dense canopy. These stands still occur in Bolivia, and the tree is common in parts of Argentina.Grau, H. R. (2000)Regeneration patterns of ''Cedrela lilloi'' (Meliaceae) in northwestern Argentina subtropical montane forests.''Journal of Tropical Ecology'' 16(2) 227-42. However, it is a valuable timber tree. Some populations have faced substantial declines, and it is considered to be an endangered species An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martín Sessé Y Lacasta
Martín Sessé y Lacasta (December 11, 1751 – October 4, 1808) was a Spanish botanist, who relocated to New Spain (now Mexico) during the 18th century to study and classify the flora of the territory. Background Sessé studied medicine in Zaragoza, then moved to Madrid in 1775. In 1779 he became a military physician, in which capacity he visited Cuba, and later New Spain. In 1785 he was named a commissioner of the Royal Botanical Garden in New Spain. At the same time a botanical garden and a course of study on the flora of Mexico at the Royal and Pontifical University of Mexico (now UNAM) were authorized. Sessé stopped practicing medicine in order to devote all his energies to botany. The botanical expedition In 1786 Charles III, King of Spain, authorized a major botanical expedition known as the Royal Botanical Expedition to New Spain, that was proposed by Sessé at a time when most of the flora and fauna of Mexico were unknown to European science. Sessé became the head ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endangered Flora Of South America
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of Peru
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
