| World first managed teak plantation was introduced by the Dutch in the 17 th century (1680). The first planting of teak by the Forestry Department in Sri Lanka dates back to 1872. Since then teak has been planted as a main species under the dry zone reforestation programme. At present, there are about 70,000 ha of teak plantations of various age classes. Teak is neither imported into nor exported from Sri Lanka . Products of the teak plantations are used locally. |
| Mahogany ( swietenia macrophylla ), one of the most prized timbers in the world, is difficult to grow in plantations. GGF is basing its figures and explanations on the production of teak but we do intend to grow small amounts of mahogany as well. Should the mahogany fail it will be replaced with teak. The main reason for the failure of mahogany when grown in a plantation is because of the damage done by the mahogany shoot borer, Hypsipyla grandella,which bores into twigs and seed capsules of trees. Mahogany shoot borers attack new shoots and are seldom seen attacking hardened-off shoots. Mahogany trees are susceptible to attack when they reach a height of 0.5 meter (Griffiths 2001). The insect's most severe damage to trees occurs when a larva bores into and kills the terminal shoot. A lateral branch grows upward to replace the lost terminal shoot, resulting in a crooked main stem. Small trees whose terminal shoots are attacked repeatedly in successive years become extremely deformed. Growing mahogany is possible but it is best to do on a less intensive scale |
