Vegetation of the Sierra Madre Occidental, Mexico: a synthesis
The Sierra Madre Occidental (SMO) is the largest mountain range in Mexico, extending along more than 1200 km from northeastern Sonora (30°35' N) ca at the US-Mexico border to northern Jalisco (21°00' N) on western Mexico. It includes part of the states of Sonora, Chihuahua, Durango, Zacate...

| description | The Sierra Madre Occidental (SMO) is the largest mountain range in Mexico, extending along more than 1200 km from northeastern Sonora (30°35' N) ca at the US-Mexico border to northern Jalisco (21°00' N) on western Mexico. It includes part of the states of Sonora, Chihuahua, Durango, Zacatecas, as well as small areas of Sinaloa, Nayarit, Jalisco, and Aguascalientes. Of major ecological and economical importance, with a high biological and cultural diversity, this cordilleran complex is not yet well known. For this area, information about the different vegetation types, their elevational ranges, and the climates influencing them, is presented, as is a map showing the geographical distribution of the vegetation types. The area encompasses a confluence of Madrean, Xerophytic Madrean, and Tropical ecosystems. The Madrean region, with temperate and semi-cold climates, includes five vegetation types: pine forest, mixed-conifer forest, pine-oak forest, oak forest and temperate mesophytic forest, as well as communities of primary and secondary chaparral and montane meadow vegetation. The Xerophytic Madrean region, at foothills and eastern branches of the cordillera, has temperate or semi-cold dry climates and a vegetation of oak or pine-oak woodland and evergreen Juniperscrub, with transitions toward the grassland and xerophytic scrub areas of the Mexican high plateau or even to the subtropical scrub at the southern area of the Madrean Archipelago subregion. The Tropical region, entering the SMO through the deep canyons on the western flanks, has warm, semi-warm, and dry-warm climates and a prevalence of tropical deciduous forest and subtropical scrub, with small areas of tropical semideciduous forest. The high species richness of this range can be exemplified with the three physiognomically dominant genera: 24 species of Pinus (46% of the Mexican total), 54 species of Quercus (34%), and 7 species of Arbutus (100%). |

La Sierra Madre Occidental (SMO) es el complejo montañoso más grande de México, extendiéndose por casi 1200 km desde el noreste de Sonora (30°35' N) hasta el norte de Jalisco (21°00' N). A pesar de su gran importancia ambiental y económica, es todavía deficientemente conocida. Se presenta una sinopsis de los tipos de vegetación, con datos sobre la superficie que ocupan las comunidades reconocidas, intervalos de elevación y climas donde se localizan, así como un mapa. En la zona confluyen tres regiones, albergando ecosistemas templados y semifríos (región Madrense), semiáridos (Madrense-Xerófila) y cálido-secos (Tropical), respectivamente. La región Madrense, en el macizo de la sierra, incluye bosque de pino, bosque mixto de coníferas, bosque de pino-encino, bosque de encino y manchones de bosque mesófilo de montaña, además de comunidades como chaparral (primario y secundario) y vegetación de claros de bosque. La región Madrense-Xerófila, en el piedemonte norte y oriental y estribaciones al oriente de la sierra, presenta bosque bajo abierto (de encino o de pino-encino), matorral perennifolio y zonas de ecotonía hacia pastizal y matorral xerófilo, además de ecotonías con matorral subtropical hacia el sur del Archipiélago Madrense. En la región Tropical, a lo largo de la base occidental de la sierra e ingresando a esta a través de las barrancas y quebradas, predomina bosque tropical caducifolio y matorral subtropical, con pequeñas áreas de bosque tropical subcaducifolio. La alta diversidad de la SMO se ejemplifica con los tres géneros dominantes fisonómicamente en la vegetación: 24 especies de Pinus (46% del total nacional), 54 de Quercus (34%) y 7 de Arbutus (100%).
