Stocking and composition of second rotation forests

Samsudin Musa, . and Abd Rahman Kassim, . and Khairul Najwan, . (2005) Stocking and composition of second rotation forests. [Proceedings Paper]

The management of forests in Malaysia is expected to face new challenges as exploitation of production forests are shifting from the generally rich and productive undisturbed forests to logged-over forests. In the near future all forest harvesting activities are expected to be operating only in logged-over forests. In this respect there are concerns that logged-over forests which are in their second rotation are not as rich and well stocked as the undisturbed forests and thus hamper future supply of quality raw materials. According to the forest management systems applied in these forests namely the Selective Management System SMS and the Malayan Uniform System MUS the residual forest should be able to recover within specified rotation cycles and should produce sufficient quality crop for the second and subsequent harvests. To assess this situation a study was conducted to assess stockings and species composition of second rotation forests in two production forests located in Tekam Forest Reserve Pahang and Cherul Forest Reserve Terengganu. The study indicated that the second rotation forests are not as productive as predicted but are still able to produce an economic yield within the specified rotation cycle. However species composition was altered and favouring non-dipterocarp species. Some of the factors contributing to this phenomenon include slower recovery of the forest after the first cut higher mortality due to logging damage and implementation of cutting limit prescriptions that favours high removal of dipterocarps.

Abstract

The management of forests in Malaysia is expected to face new challenges as exploitation of production forests are shifting from the generally rich and productive undisturbed forests to logged-over forests. In the near future all forest harvesting activities are expected to be operating only in logged-over forests. In this respect there are concerns that logged-over forests which are in their second rotation are not as rich and well stocked as the undisturbed forests and thus hamper future supply of quality raw materials. According to the forest management systems applied in these forests namely the Selective Management System SMS and the Malayan Uniform System MUS the residual forest should be able to recover within specified rotation cycles and should produce sufficient quality crop for the second and subsequent harvests. To assess this situation a study was conducted to assess stockings and species composition of second rotation forests in two production forests located in Tekam Forest Reserve Pahang and Cherul Forest Reserve Terengganu. The study indicated that the second rotation forests are not as productive as predicted but are still able to produce an economic yield within the specified rotation cycle. However species composition was altered and favouring non-dipterocarp species. Some of the factors contributing to this phenomenon include slower recovery of the forest after the first cut higher mortality due to logging damage and implementation of cutting limit prescriptions that favours high removal of dipterocarps.
