A Half-yearly Peer Reviewed Journal of Bangladesh Forest Research Institute
The paper evaluates the Teak (Tectona grandis Linn.) plantation programmes of Bangladesh in order to develop a suitable strategy for its long-term planning.
The percentage of Teak plantation in Cox’s Bazar, Chittagong, Chittagong Hill Tracts (North), Chittagong Hill Tracts (South) and Sylhet Forest Divisions stands at 28, 20, 14, 14, and 12 respectively. 1-14 year and 15-29 year plantations constitute 48% and 45%
respectively.
The marginal value growth percent in good Teak plantations comes close to zero beyond 40 years. The ratio of basal area growth of non-Teak species to Teak in the mixed plantations of age 33 to 55 years ranges between 1.36 to 2.40 indicating that Teak grows poorly compared to many other species. Yield data have been compared with those of other Teak growing countries. It is concluded that there should be no plantation in sites worse than SI 30.
Assuming per capita consumption of 0.10 m3 and population growth rate as much as 0.30%, total Teak requirement by 2040 a. would be about 1.05 lakh m3 which amounts to 5% of total output. The required plantation area should lie between 3 and 5 percent only. The existing proportion of 70% is not economically justified. Five strategies with respect to sites, rotation, thinning and stocking are pointed out in order to make long-term programme consistent with socio-economic goals and national forest policy.
