Wild teak forests continue to decline, threatening genetic diversity, while commercial planted teak forests are on the rise, according to a new assessment by the Food and Agriculture Organization (FAO). Overall, teak forests have declined by 1.3 percent, or 385,000 hectares, worldwide from 1992 to 2010. Teak (Tectona grandis) is used for a variety of commercial purposes, including outdoor furniture and flooring. Wild teak forests are found only in four countries, three of which—India, Laos, and Myanmar—have seen declines, while Thailand has seen an increase in its teak forest by nearly 3 million hectares. India has lost the most teak forest in the last two decades, falling around 2.1 million hectares, meanwhile Myanmar lost just over a million hectares and Laos 68,500 hectares. Thailand has banned logging in natural forests since 1989, which the assessment says may be the reason behind its rise in teak forests. \"Supply trend points to a continuing decline in the volume and quality of natural teak, which results in progressive loss of genetic resources. This is why it is essential in the near future to plan, organize and implement a programme for the genetic conservation of native teak resources in the four countries with natural teak forests,\" said Walter Kollert, FAO Forestry Officer, in a press release. Even as wild teak declines, commercial teak plantations are on the rise. Such forests are increasingly grown outside of teak range countries, including Africa, Central and South America, and Indonesia, but India is still the largest holder of commercial teak plantations, making up 38 percent of the world\'s total. Teak has not been evaluated by the IUCN Red List.
