Forestry In Mexico
The forests of Mexico cover a surface area of about 64 million hectares, or 34.5% of the country. These forests are categorized by the type of tree and biome: tropical forests, temperate forests, cloud forests, riparian forests, deciduous, evergreen, dry, moist, etc.. The agency in charge of Mexico's forests is the ''Comisión Nacional Forestal''. Despite major reforms to the Mexican Constitution in 1992 regarding private land, Mexico would later enact major forest regulation laws in 1998 and 2003. Though no longer required to enforce land regulation in Mexico, Article 27 of the Mexican Constitution also still permits the Mexican Government to enact land regulation. History Forest areas were historically part of indigenous communities' commons for hunting, gathering, and fuel. Areas of Mexico were deforested in the prehispanic period around Teotihuacan. In the colonial era, forests were a source of timber for construction, for fuel in smelting metals, and for household fuel. Fores ...

Bosque Cajonos
A bosque ( ) is a type of gallery forest habitat found along the riparian flood plains of stream and river banks in the southwestern United States. It derives its name from the Spanish word for 'woodlands'. Setting In the predominantly arid or semi-arid southwestern United States, a bosque is an oasis-like ribbon of green vegetation, often canopied, that only exists near rivers, streams, or other water courses. The most notable bosque is the -long ecosystem along the valley of the middle Rio Grande in New Mexico that extends from Santa Fe south to El Paso, Texas. One of the most famous and ecologically intact sections of the bosque is included in the Bosque del Apache National Wildlife Refuge. Flora and fauna Common trees in the bosque habitat include mesquite, cottonwood, desert willow, and desert olive. Because there is often only a single canopy layer and because the tree species found in the bosque are generally deciduous, a wide variety of shrubs, grasses, and ...

Monarch Butterfly
The monarch butterfly or simply monarch (''Danaus plexippus'') is a milkweed butterfly (subfamily Danainae) in the family Nymphalidae. Other common names, depending on region, include milkweed, common tiger, wanderer, and black-veined brown. It is amongst the most familiar of North American butterflies and an iconic pollinator, although it is not an especially effective pollinator of milkweeds. Its wings feature an easily recognizable black, orange, and white pattern, with a wingspan of . A Müllerian mimic, the viceroy butterfly, is similar in color and pattern, but is markedly smaller and has an extra black stripe across each hindwing. The eastern North American monarch population is notable for its annual southward late-summer/autumn instinctive migration from the northern and central United States and southern Canada to Florida and Mexico. During the fall migration, monarchs cover thousands of miles, with a corresponding multigenerational return north in spring. The western ...

Bajío Dry Forests
The Bajío dry forests is a tropical dry broadleaf forest ecoregion in western−central Mexico. Geography The Bajío dry forests lie in the southwestern portion of the Mexican Plateau. They are bounded on the southeast, south, and southwest by the Trans-Mexican Volcanic Belt pine-oak forests, which occupy the folded mountains and volcanoes of the Trans-Mexican Volcanic Belt that form the southern edge of the Mexican Plateau. The Sierra Madre Occidental pine-oak forests of the Sierra Madre Occidental bound the ecoregion on the northwest. The numerous mountains of the plateau which rise above the dry forests are occupied by sky islands of pine-oak forest. To the north, the Bajío dry forests transition to the drier, more temperate Central Mexican matorral. Most of the ecoregion lies within the basin of the Lerma River, and the dry forests extend around Lake Chapala at the eastern end of the region, and into the endorheic basins of Lake Cuitzeo and Lake Pátzcuaro in the south. ...

Terrestrial Ecoregions
An ecoregion (ecological region) or ecozone (ecological zone) is an ecology, ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural community (ecology), communities and species. The biodiversity of flora (plants), flora, fauna (animals), fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregion ...

Global Ecoregion
The Global 200 is the list of ecoregions identified by the World Wide Fund for Nature ( WWF), the global conservation organization, as priorities for conservation. According to WWF, an ecoregion is defined as a "relatively large unit of land or water containing a characteristic set of natural communities that share a large majority of their species dynamics, and environmental conditions". For example, based on their levels of endemism, Madagascar gets multiple listings, ancient Lake Baikal gets one, and the North American Great Lakes get none. The WWF assigns a conservation status to each ecoregion in the Global 200: critical or endangered; vulnerable; and relatively stable or intact. Over half of the ecoregions in the Global 200 are rated endangered. Background The WWF has identified 867 terrestrial ecoregions across the Earth's land surface, as well as freshwater and marine ecoregions. The goal of this classification system is to ensure that the full range of ecosystems wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It grows at high altitudes of in cloud forests with cool, humid summers and dry winters in most of its habitat regime. In the state of Veracruz, it grows with precipitation all year long. The tree is resistant to regular winter snowfalls. Names The Spanish name comes from the Nahuatl word ''oyametl'' (''oya'', "to thresh"; ''metl'', "agave"; literally "threshing agave").

Metres Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...
