Trans-Mexican Volcanic Belt pine–oak forests

Pinus hartwegii forest

Trans-Mexican Volcanic Belt pine–oak forests are a biogeographic zone characterized by a diverse mosaic of pine and oak forests located across the Trans-Mexican Volcanic Belt in Mexico. This region represents a unique ecosystem that spans from the Pacific coast of Michoacán to the Gulf of Mexico, covering a wide range of elevations and climates. The forests are notable for their high biodiversity, including a significant number of endemic and threatened species.

Location and Description

The Trans-Mexican Volcanic Belt pine–oak forests stretch across the volcanic belt that bisects the central part of Mexico, influencing the climate and geography of the region. These forests are found at elevations ranging from 1,500 to 3,400 meters above sea level, where the climate varies from semi-arid to humid, depending on the altitude and orientation of the slopes.

Biodiversity

The biodiversity within these forests is exceptionally high, particularly in terms of flora and fauna. The area is home to over 100 species of oak (Quercus spp.) and numerous pine (Pinus spp.) species, making it one of the most diverse temperate forests in the world. In addition to these, there are also various species of fir (Abies spp.) and juniper (Juniperus spp.) present.

The fauna is equally diverse, with numerous species of birds, mammals, reptiles, and amphibians. Many of these species are endemic to Mexico, such as the Transvolcanic jay (Aphelocoma ultramarina) and the Mexican volcano mouse (Neotomodon alstoni). The region also serves as a critical habitat for migratory species, including the monarch butterfly (Danaus plexippus).

Conservation

Despite its ecological importance, the Trans-Mexican Volcanic Belt pine–oak forests face several threats, including deforestation, land use change, and climate change. These threats are primarily driven by agricultural expansion, urban development, and illegal logging. Conservation efforts are underway to protect and restore these vital ecosystems, including the establishment of protected areas and reforestation projects.

Protected Areas

Several protected areas have been established within the Trans-Mexican Volcanic Belt pine–oak forests to conserve the unique biodiversity of the region. These include national parks, biosphere reserves, and other types of conservation areas. Notable examples include the Monarch Butterfly Biosphere Reserve and the Nevado de Toluca National Park.
