Situated in the state of Queretaro, Sierra Gorda Biosphere Reserve covers an area of more than 946,000 acres (383,000hectares) consisting of 15 types of vegetation including evergreen and deciduous tropical forest, shrubs and cacti, oak forests, pine forests and cloud forests.

Conservation Action

Although called a reserve, much of the land inside Sierra Gorda Biosphere Reserve boundaries is in private ownership and therefore unprotected. World Land Trust (WLT) is working with GESG to bring as much of this land under protection as possible.

Threats include cattle ranching, slash and burn forest clearance, illegal hunting, timber extraction and inefficient agricultural practices which lead to soil erosion. Mining and associated pollution, together with urban sprawl also threaten this biodiverse habitat.




WLT has enabled GESG to purchase many reserves within Sierra Gorda and is continuing to raise funds to help GESG purchase and protect more wildlife habitat in this area of high biological importance.

Current reserves supported include:

Las Arenitas

Las Canalitas

El Canón del Fresno

Cerro Prieto-Cerro

Hoya Verde
