The Sierra Gorda is an ecological region centered on the northern third of the Mexican state of Querétaro and extending into the neighboring states of Guanajuato, Hidalgo and San Luis Potosí. Within Querétaro, the ecosystem extends from the center of the state starting in parts of San Joaquín and Cadereyta de Montes municipalities and covering all of the municipalities of Peñamiller, Pinal de Amoles, Jalpan de Serra, Landa de Matamoros and Arroyo Seco, for a total of 250 km2 of territory. The area is extremely rugged with high steep mountains and deep canyons. As part of the Huasteca Karst, it also contains many formations due to erosion of limestone, especially pit caves known locally as sótanos. The area is valued for its very wide diversity of plant and animal life, which is due to the various microenvironments created by the ruggedness of the terrain and wide variation in rainfall. This is due to the mountains’ blocking of moisture coming in from the Gulf of Mexico, which generally makes the east side fairly moist and the west semiarid scrub brush. Most of the region is protected in two biosphere reserves, with the one centered in Querétaro established in 1997 and the one centered in Guanajuato established in 2007. The Sierra Gorda is considered to be the far west of the La Huasteca region culturally and it is home to the Franciscan Missions in the Sierra Gorda of Querétaro World Heritage Site. Sierra Gorda has become the first National Park in Mexico to join the EarthCheck Sustainable Destinations program.
The Sierra Madre de Oaxaca pine–oak forests is a tropical and subtropical coniferous forests ecoregion in Southern Mexico.
The Sierra Madre Oriental pine–oak forests are a temperate broadleaf and mixed forest ecoregion of northeastern and Central Mexico, extending into the state of Texas in the United States.
The Trans-Mexican Volcanic Belt pine–oak forests is a subtropical coniferous forest ecoregion of the Trans-Mexican Volcanic Belt of central Mexico.

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, 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.
Mapastepec is a town and municipality in the Mexican state of Chiapas in southern Mexico. Its name derives from the place name mapachtepec, "Hill of the Raccoon", a compound of the Nahuatl words mapachi ("raccoon") and tepetl ("mountain").
The Selva Zoque, which includes the Chimalapas rain forest, is an area of great ecological importance in Mexico. Most of the forest lies in the state of Oaxaca but parts are in Chiapas and Veracruz. It is the largest tract of tropical rainforest in Mexico, and contains the majority of terrestrial biodiversity in the country. The forest includes the Selva El Ocote, a federally-protected biosphere reserve, but is otherwise not yet protected. Despite the rich ecology of the region, a 2003 study that focused on bird populations stated that "the fauna of the heart of the Chimalapas, including its vast rainforests, have seen little or no study". As it is an impoverished region, efforts to preserve the ecology are often at odds with demands to improve the economy.
The Sierra Madre del Sur pine–oak forests is a subtropical coniferous forest ecoregion in the Sierra Madre del Sur mountain range of southern Mexico.
The Tehuacán-Cuicatlán biosphere reserve is a protected natural area located in southeastern Mexico.

The Mapimí Biosphere Reserve is a UNESCO Biosphere Reserve located in the state of Durango in northern Mexico. It is one of three biosphere reserves representing the Chihuahuan Desert. The 342,388 hectares (1,321.97 sq mi) reserve is situated between the Neotropical and Nearctic biogeographic realms, in the Bolsón de Mapimí 1,150 metres (3,770 ft) above sea level. It contains three core areas in the Sierra de la Campana, the Laguna de las Palomas, a salt lagoon, and a desert habitat called Dunas de la Soledad. It comprises fragile warm desert and semi-desert ecosystems and rich, highly adapted but vulnerable plant systems, mainly xerophytic matorral scrub, and animal species such as the puma, mule deer, sandhill crane and the kit fox or zorrita del desiert along with scrub and desert grasslands.
The Volcán Tacaná Biosphere Reserve is a UNESCO Biosphere Reserve at the Tacaná Volcano in Chiapas, Mexico, on the border with Guatemala. The volcano is part of the Central America Volcanic Arc. The 6,378 hectares (24.63 sq mi) reserve contains fragile ecosystems very rich in wild flora and fauna species of cultural, scientific, economic and biological relevance. Its rich biodiversity and high endemism are found particularly in the high mountain ecosystem and landscapes and in the volcanic edifice which presents geophysical features of great scientific and aesthetic value. Average annual rainfall can amount to 2,000–5,000 millimetres (79–197 in), as in the case of Soconusco.
