In Mexico, the ejido system of communal land tenure has contributed to extensive deforestation leading to the loss of primate populations and other wildlife. Ejidos are peasant communities given use of land by the government. It covers millions of hectares and has led to major forest loss through slash-and-burn agriculture. Concurrently the state of Quintana Roo began the forest management program within the ejido system under the auspices of Sociedad de Productores Forestales Ejidales de Quintana Roo. Here, a village-sustainable logging system initiated at Petacab village, Quintana Roo, which has reduced levels of deforestation whilst benefiting villagers and wildlife, is summarised.
Study area and logging system: The author observed one of the village-sustainable logging projects in 1995, located at Petacab village. About half of the 54,000 ha area was utilized for logging and chicle production. The forest is divided into sections harvested under 25-year logging regimes. Before 1983, timber was extracted by the government. The community-based system was then initiated under a program which transferred forest management to a villager-managed cooperative. It allows the villagers to sell harvested timber, with profits distributed equally to around 200 ejido partners. The initial 3-year pilot plan was organized by government technicians, who convinced the villagers of the conservational value of the program and its economic value for them. Technicians also conduct forest surveys and give advice.
The forests are managed for the two species of trees used in the chicle industry (Brosimum alicastrum and Manilkara zapota) and others used for timber products. Mahogany Swietenia macrophylla and cedar Cedrela mexicana are grown in small clearings. Approximately 20,000 ha are used for agriculture and there is a small area (300 ha) of protected forest.
Monitoring: Within permanent plots, studies and monitoring has been undertaken on a long-term basis, concentrating on species of commercial value; however an aim is to maintain species diversity as a whole.
The Petacab project has proven successful in balancing sustainable forest use and forest conservation, which is benefiting for black howlers, spider monkeys Ateles geoffroyi and other wildlife.
