Grupo Ecológico Sierra Gorda I.A.P. (GESG) was founded in 1987 as an authorized civil society organization whose mission is to conserve the natural wealth by generating development opportunities for the landowners and replicating their projects in other areas of Mexico. It does so by uniting citizens with institutional, national, and international efforts. Its lines of work include training and environmental education, managing solid waste, fundraising, defending the territory, influencing public policies, and consolidating a conservation economy in the region. Together with the sister organizations that share its objective, GESG leads and coordinates the Conservation Alliance for the Sierra Gorda Biosphere Reserve, building solid social participation among the all-level networks with which it works. In this way, it protects the ecosystems and species of the Reserve.
