References. Annexure I Glossary. Annexure II Abbreviations used. From the preface: "Forest management is multi- dimensional. The list of d…imensions begins with 'ecological', and, perhaps,ends with 'political'. In various contexts, one or the other dimension assumes greater importance. Neverthless, the silvicultural dimension remains a key dimension in any context. "In the last few decades, there have been rapid changes in imperatives in forest management. If timber production was the primary objective in forest management in nineteen- forties, biodiversity conservation is the main concern in nineteen- nineties. Unfortunately, despite regular debate, the silvicultural systems have not changed with the changing objectives. "This work is an attempt to initiate search for the new systems. The author's experience is limited to tropics, so are the discussions in this work." No. 29920 137 pp.
