They slowly built their own lumber business and, at the same time, began studying how to protect the forest. Now, the town’s enterprises employ 300 people who harvest timber, produce wooden furniture and care for the woodlands, and Ixtlán has grown to become the gold standard of community forest ownership and management, international forestry experts say.

Mexico’s community forest enterprises now range from the mahogany forests of the Yucatán Peninsula to the pine-oak forests of the western Sierra Madre. About 60 businesses, including Ixtlán, are certified by the Forest Stewardship Council in Germany, which evaluates sustainable forestry practices. Between 60 and 80 percent of Mexico’s remaining forests are under community control, according to Sergio Madrid of the Mexican Civic Council for Sustainable Forestry.

“It’s astounding what’s going on in Mexico,” said David Barton Bray, an expert on community forestry at Florida International University who has studied Ixtlán.

The Mexican government plans to showcase its success in community forestry at the global climate talks in Cancún next week. Despite fractious negotiations over reducing carbon emissions, talks on paying developing countries to protect their forests have moved further ahead than most other issues.

In developing countries, where the rule of law is weak and enforcement spotty, simply declaring a forest off-limits does little to prevent illegal logging or clearing land for agriculture or development. “Unless local communities are committed to conserving and protecting forests it’s not going to happen,” said David Kaimowitz, a former director of the Center for International Forestry Research, or Cifor, who is now at the Ford Foundation. “Government can’t do it for them.”
