Forests Of 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 National Forestry Commission (''Comisión Nacional Forestal''). Despite major reforms to the Constitution in 1992 regarding private land, Mexico enacted major forest regulation laws in 1998 and 2003. Though no longer required to enforce land regulation in Mexico, Article 27 of the Constitution also still permits the 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 streams, river banks, and lakes. It derives its name from the Spanish word for "forest", pronounced . Setting In the predominantly arid or semiarid Southwestern United States, a bosque is an oasis-like ribbon of green forest, often canopied, that only exists near rivers, streams, or other water courses. The most notable bosque is the -long forest ecosystem along the valley of the middle Rio Grande in New Mexico that extends from Santa Fe, through Albuquerque and 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, which is located south of San Antonio, NM. Another bosque can be found in Costa Rica, a beautiful wildlife refuge named Bosque Alegre.

Yucatán Peninsula
The Yucatán Peninsula ( , ; ) is a large peninsula in southeast Mexico and adjacent portions of Belize and Guatemala. The peninsula extends towards the northeast, separating the Gulf of Mexico to the north and west of the peninsula from the Caribbean Sea to the east. The Yucatán Channel, between the northeastern corner of the peninsula and Cuba, connects the two bodies of water. The peninsula is approximately in area. It has low relief and is almost entirely composed of porous limestone. The peninsula lies east of the Isthmus of Tehuantepec, the narrowest point in Mexico separating the Atlantic Ocean, including the Gulf of Mexico and Caribbean Sea, from the Pacific Ocean. Some consider the isthmus to be the geography, geographic boundary between Central America and the rest of North America, placing the peninsula in Central America. Politically, all of Mexico, including the Yucatán, is generally considered part of North America, while Guatemala and Belize are considered pa ...

Terrestrial Ecoregions
An ecoregion (ecological region) is an ecology, ecological and Geography, geographic area that exists on multiple different levels, defined by type, quality, and quantity of environmental resources. 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). Ecoregions are also known as "ecozones" ("ecological zones"), although that term may also refer to biogeographic realms. Three caveats are appropriate for all bi ...

Global Ecoregion
The Global 200 is the list of ecoregions identified by the World Wide Fund for Nature (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 ecoregion, freshwater and marine ecoregions. The goal of this classification system is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry Forest
The tropical and subtropical dry broadleaf forest is a habitat type defined by the World Wide Fund for Nature and is located at tropical and subtropical latitudes. Though these forests occur in climates that are warm year-round, and may receive several hundred millimeters of rain per year, they have long dry seasons that last several months and vary with geographic location. These seasonal droughts have great impact on all living things in the forest. Deciduous trees predominate in most of these forests, and during the drought a leafless period occurs, which varies with species type. Because trees lose moisture through their leaves, the shedding of leaves allows trees such as teak and mountain ebony to conserve water during dry periods. The newly bare trees open up the canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. Trees on moister sites and those with access to ground water tend to be evergreen. Infertile sites also te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oyamel
''Abies religiosa'', the oyamel fir or sacred fir, (known as in Spanish) is a fir native to the mountains of central and southern Mexico (Trans-Mexican Volcanic Belt, Sierra Madre del Sur) and western Guatemala. It grows at high elevations 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 which occur near the upper altitudinal limit of its growth. Names The Spanish name comes from the Nahuatl word ''oyametl'' (''oya'', "to thresh"; ''metl'', "agave"; literally "threshing agave"). It is also called (Christmas tree) in Mexico. The English name derives from the binomial ''Abies religiosa'', literally "religious fir". This comes from the use of its cut foliage in religious festivals (notably at Christmas) and in churches in Mexico.

Metres Above Sea Level
Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods. Climate change and other forces can cause sea levels and elevations to vary over time. Uses Elevation or altitude above sea level is a standard measurement for: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Mining infrastructure, particularly underground. * Flying objects such as airplanes or helicopters below a Transition Altitude defined by local regulations. Units and abbreviations Elevation or altitude is generally expressed as "metres above mean sea level" in the metric system, or " feet above mean sea level" in United States customary and imperial units.

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 among the most familiar of List of butterflies of North America, 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 Monarch butterfly migration, 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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monarch Butterfly Biosphere Reserve
The Monarch Butterfly Biosphere Reserve () is a World Heritage Site containing most of the overwintering sites of the eastern population of the monarch butterfly. The reserve is located in the Trans-Mexican Volcanic Belt pine-oak forests ecoregion on the border of Michoacán and State of Mexico, 100 km (62 miles), northwest of Mexico City. Millions of butterflies arrive in the reserve annually. Butterflies only inhabit a fraction of the 56,000 hectares of the reserve from October–March. The biosphere's mission is to protect the butterfly species and its habitat. Most of the overwintering monarchs from eastern North America are found here. Researchers discovered these areas in 1975. Presidential decrees in the 1980s and 2000 designated these still privately held areas as a federal reserve. The Reserve was declared a Biosphere Reserve in 1980 and a World Heritage Site in 2008. The reserve remains predominantly rural. Reserve administrators continue to be concerned with del ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
