Quercus Furfuracea
''Quercus furfuracea'' is a species of oak native to eastern Mexico. Description ''Quercus furfuracea'' is a shrub or small tree, which grows to 3 to 6 meters tall. The species belongs to the ''Quercus acutifolia'' group of species. The species of this group are characterized by lanceolate to elliptical leaves which are glabrous on both surfaces, with a dentate-aristate margin, and some clustered trichomes in the axils of the veins.Valencia Avalos, Susana (2010). "Notes on the Genus ''Quercus'' in Mexico". ''International Oak Journal'' No. 21 Spring 2010 Range and habitat ''Quercus furfuracea'' is native to the Sierra Madre Oriental, in the states of Puebla, Hidalgo, and San Luis Potosí. It is a rare species, occupying only a few locations across its range. It has an estimated extent of occurrence (EOO) of 18,575 km2, and an estimated area of occupancy (AOO) of 60 km2. The area of occupancy is likely an under-estimate, due to under-sampling. It inhabits montane oak forests, pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of The Sierra Madre Oriental
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably '' Lithocarpus'' (stone oaks), as well as in those of unrelated species such as ''Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species. Description Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Pinus Patula
''Pinus patula'', commonly known as patula pine, spreading-leaved pine, or Mexican weeping pine, and in Spanish as ''pino patula'' or ''pino llorón'', (''patula'' Latin = “spreading”) is a tree native to the highlands of Mexico. It grows from 24° to 18° North latitude and above sea level. The tree grows up to tall. It cannot withstand long periods of temperatures as low as , but resists occasional brief dips below . It is moderately drought-tolerant, and in this respect is superior to ''Pinus taeda''. The average annual rainfall in its native habitat is from 750 to 2000 mm. This happens mostly in summer, but in a little area of the State of Veracruz on the Sierra Madre Oriental its habitat is rainy the year round. It is planted at high altitudes in Ecuador (3500 m), Bolivia, Colombia (3300m), Kenya, Tanzania, Angola, Zimbabwe, Papua New Guinea, and Hawaii (3000 m).

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa.
