Clonal forestry of teak has already been widely operatedmainly in South East Asia including Indonesia . Clonal forestry is designed to produce thehighest effect of selection using the genetically identical individuals. Themistake on clones management directly effects the productivity on operationaland the efficiency of tree improvement program. Under the proper management ofclones , clonal forestry can provide various superior effects such as greatergenetic grain, greater uniformity and the opportunity to speed up results fromtree improvement activities. Clonal forestry is not without its risks. If notdone properly it could endanger subsequent crops by producing in adequate genetic variation , Which inturn increases risk of pest attack , disease , wind throw or other harzard. Tocounter inadequate variation , It is necessaryto use large numbers of clones should be compensated by the continualintroduction of new genotyps for testing. At the same time it is necessary toensure the conservation of natural gene pools.
