References. Annexure I Glossary. Annexure II Abbreviations used. From the preface: "Forest management is multi- dimensional. The list of dimensions 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.

The author's experience is limited to tropics, so are the discussions in this work." No. 29920 137 pp.…
