 Most conservation in the Sierra Madre de Oaxaca is controlled by indigenous communities.For example, Santiago Comaltepec's vast expanse of cloud forests is considered some of the best conserved cloud forests in the world.Many communities, notably Ixtlán de Juárez and the Pueblos Mancomunados, among others, strive to conserve their forest through projects including sustainable forestry and selective logging, ecotourism, education projects, and the prohibition of private property within their communities (thus hampering unsustainable development and industry by foreign or outside agents).
