40-Year Rotation of Teak Plantations in Thailand 2015.
In natural forest, teak takes 150 years to reach maturity. The Royal Forest Department assumes that the girth at maturity of this famous timber should be 213 cm. at breast height. But teak grown in plantation will take only 40 years.
Teak in Thailand is found extensively in the north and stretches along the western border down to latitude 14°N, i.e. the whole range extends from 14°N to 20°31 N and west to east longitude 97°30E to 104°30E at altitudes between 100-900 m above mean sea level (Mahaphol, 1954). Teak was associated with other species in the mixed deciduous forest, which at that time was estimated at 9,297,300 ha. It was assumed that approximately one-fourth of the forest land was under teak,
i.e. the teak-bearing area was 2,324,300 ha. A number of factors control the distribution and growth of teak, including rainfall/soil moisture, temperature, light, geographical
formation, and soil conditions (Kaosa-ard, 1980).
