	Sierra Madre Oriental. The Columbia Gazetteer of North America. 2000
		Sierra Madre Oriental (see-ER-rah MAHD-rai o-ree-en-TAHL), mountain range, E Mexico, extending for approx.
		This sector of the sierra is formed by a series of discrete, parallel, fault-block ranges, some of which also show evidence of volcanic activity.
		The S sector, which is more rugged and higher than the N, comprises the E escarpment of the Mexican Plateau and is composed mainly of folded limestone ridges that rise from the coastal plain in a series of increasingly higher steps to the plateau surface at an elevation of 7,000 ft/2,130 m–8,000 ft/2,440 m.

	Terrestrial Ecoregions -- Sierra Madre Oriental pine-oak forests (NA0303)
		In the northernmost portions of the ecoregion, the forests occur on irregular hummocks that constitute biological "islands" of temperate forest in the middle of the Chihuahuan Desert.
		The Sierra Madre Oriental pine-oak forests represent an island of temperate environments surrounded by more humid and tropical ecoregions to the south, and xeric ecoregions to the north.
		The maroon-fronted parrot (Rhynchopsitta terrisi) (VU) and the Colima warbler (Vermivora crissalis) (nt) are endemic to the Sierra Madre Oriental ecoregion (Stattersfield 1998).

	Mexico - Topography and Drainage
		The Sierra Madre Occidental on the west is a continuation of California's Sierra Nevada (with a break in southeastern California and extreme northern Mexico), and the Sierra Madre Oriental on the east is a southward extension of the Rocky Mountains of New Mexico and Texas.
		The Sierra Madre Occidental lies approximately 300 kilometers inland from the west coast of Mexico at its northern end but approaches to within fifty kilometers of the coast near the Cordillera Neovolcánica.
		As is the case with the Sierra Madre Occidental, the Sierra Madre Oriental comes progressively closer to the coastline as it approaches its southern terminus, reaching to within seventy-five kilometers of the Gulf of Mexico.

	Sierra Madre Oriental - Wikipedia, the free encyclopedia
		The Sierra Madre Oriental is a mountain range in northeastern Mexico, spanning 1000 km from Coahuila south through Nuevo León, southwest Tamaulipas, San Luis Potosí, Hidalgo, to northern Puebla and Querétaro, where it joins with the Sierra Madre Occidental and the Eje Volcánico Transversal of central Mexico.
		Another high point of this system is El Coahuilón with about (3460 m) The range is noted for its high biodiversity and large number of endemic species.
		Although separated from the main part of the Sierra Madre Oriental by the Rio Grande, the Chisos Mountains in Big Bend National Park, southwest Texas are floristically part of the Sierra Madre Oriental.

	Biodiversity Hotspots - Madrean Pine-Oak Woodlands - Conservation Action
		Most of the endemic terrestrial vertebrate species in Mexico that are still unprotected are located on the southern slopes of the Sierra Madre del Sur and, to a lesser extent, on the western slopes of the Sierra Madre Occidental and the eastern slopes of the Sierra Madre Oriental, making this hotspot an important conservation priority.
		In the Sierra Madre Occidental, the 48-km² Cumbres de Majalca National Park, the 58-km² Cascada de Basaseachic National Park and the 93-km² La Michilía Biosphere Reserve conserve notable stands of pine-oak formations.
		The Sierra Madre Alliance, a network of Mexican and international partners working in the Sierra Madre Occidental in Chihuahua, aims to preserve biodiversity and restore the functioning of forested ecosystems through local participation.

		In Mexico, the Cordillera divides into the western Sierra Madre Occidental and the eastern Sierra Madre Oriental, separated by the southern extension of the Basin and Range and the Central Mesa before joining with the Sierra Madre del Sur, which then passes into the Central American orogenic belt.
		The Sierra Madre Oriental trends northwest over most of its length, but splits abruptly in this scene into a western branch and the Cross Ranges, then northward to rejoin the trend in the Basin and Range section.

		The forest of the high mountains of northern Mexico, most notably that found in the Sierra Madre Occidental and Sierra Madre Oriental, is composed of a mixture of conifers (softwoods) and largely evergreen flowering trees (hardwoods).
		On the western slope of the Sierra Madre Occidental, precipitation can exceed 50 in (140 cm), but on its more arid eastern slope (and the western slope of the Sierra Madre Oriental), the rate rarely exceeds 30 in (75 cm).
		Amounts in the southern portion of these ranges and in the so-called "Trans-volcanic Belt" (a series of high mountains at the southern end of the Chihuahuan Desert mainly of volcanic origin) can be even greater.
