How WLT is helping

WLT has already 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.

Urgent funding needed

This project is funded through Buy an Acre. Funding is needed to purchase and protect more areas within Sierra Gorda Biosphere Reserve to ensure this unique habitat and its diverse wildlife remain protected.

Threats to Sierra Gorda

Although called a reserve, much of the land inside Sierra Gorda Biosphere Reserve boundaries is in private ownership and therefore unprotected.

  • 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.
El Jagueycito
El Jagueycito was the first reserve purchased through buy an acre funding. Wild Turkey, Turkey Vulture and signs of Puma have all been sighted on or near this reserve

The reserves

  • Las Arenitas 

  • San Jose

  • Las Canalitas

  • La Tinaja de Climente

  • El Jagueycito

  • El Canón del Fresno

  • Cerro Prieto-Cerro La Luz

  • Cerro del Pino, Hoya Verde

As the habitat is so diverse these reserves cover a wide variation in terrain, plants and animal species.

GESG's work in Sierra Gorda also includes programmes with the local communities, such as community improvement and environmental education. In addition, GESG is involved with Sierra Gorda Eco-tours, an eco-tourism programme that reinvests the revenues generated back into the Reserve's environmental protection and community development programmes.
