ITTO
The International Tropical Timber Organization (ITTO) is an international organization promoting the conservation and sustainable management, use and trade of tropical forest resources; its members are both timber-producing and purchasing countries. It was established in 1986 and is financed via voluntary pledges. ITTO promotes the conservation and sustainable management, use and trade of tropical forest resources. Since 2006, it publishes an annual report on the status of tropical forest management in which information on the area and condition of tropical rain forests and their management are collected. Various organizations criticize the data published by FAOStat and ITTO, pointing out that these are partly wrong, incomplete and not up to date. However, due to the lack of other freely available global data sets, we use these sources of data as a reference nevertheless.
