The Myanma Selection System (MSS) has been applied in the management of the natural teak-bearing forests in Myanmar for nearly 150 years now with the belief that it can sustain the forests and teak yields. Nevertheless, over the past years the teak forests have both depleted and degraded significantly. Without a doubt, the main causes of this resource depletion and degradation included illegal cuttings, legal over-exploitation, agricultural expansion, shifting cultivation and lack of timely silvicultural treatments. As a matter of fact the MSS itself has technical weaknesses such as applying it to natural forests where light-demanding economic species are prioritized, fixing exploitable sizes, and not setting and maintaining desirable residual stand structures. In consequence, in the long run, the insufficient ingrowth has devastated stand structures of teak and other commercial species threatening the value and sustainability of the forest.
The Myanma Modified Selection System (MMSS) has attempted to address the main technical shortcomings of MSS. This study aims to apply MMSS in the management of teak-bearing natural forests in Myanmar and to test the technical feasibility of MMSS for application on a large scale and assess its value. The study was conducted in compartment 20 of Kyaukmasin reserved forest (RF) of mixed deciduours teak bearing forest. It has an area of 445 acres (approx. 180 ha). On the other hand it demands more hard work, time, skills and expenditure. In this context a pilot project is crucial to study both technical and financial feasibilities of the modified system.
