At a meeting of dendrochronologists an American colleague described the effects of volcanic eruptions on annual ring formation in bristlecone pines. I knew very little about either volcanoes or American pines! At the same meeting European scientists spoke on the dendrochronological dating of lakeshore settlements and the effects of larch bud moth attack on trees in the Alps. It is possible that American participants were not in a position to fully appreciate these papers either. In other words, dendrochronology is an extremely interdisciplinary science; its facets range from modern statistics on wood anatomy to the history of art. It is difficult even for dendrochronol ogists to keep in touch with the whole spectrum, and even more difficult for the layman to obtain an overall view of the many methods and fields of application. In recent times specialisation has begun to hinder communication be tween the various sectors. Archaeologists, for instance, set up their own dendrochronological laboratories and construct independent chronologies to serve their particular interests. The scientific institutions which previously carried out such work are now turning more and more to strongly statistically or biologically-oriented questions. The full wealth of information contained in tree rings, however, will be revealed only when dendrochronologists make a concerted effort to relate the findings of the different fields. In spite of inevitable specialisation, it is necessary that the expert concern himself with the work of his colleagues.

The analysis of tree rings has been critically important in all kinds of environmental studies including forest decline, ecological prognosis on a large scale and climate trends for the past decades to millennia. It may also provide important knowledge for forest management and the forest product industry. This book has been developed from an IUFRO meeting in Washington State, USA in July 1997 and describes the latest achievements and challenges in tree ring research from around the world.

This manual summarises information on the ecology and silviculture of the species Acacia mangium Willd, with an emphasis on Vietnam. It also encompasses growth and yield data from published sources, as well as collected from sites under smallholder industrial plantations in Phu Tho Province, Vietnam. This manual is 1 of 5 that guide smallholder tree planting of 5 selected tree species in Vietnam. The other 4 species are: Acacia hybrid, Cinnamomum parthenoxylon (Jack) Meisn, Erythrophloeum fordii Oliver and Eucalyptus urophylla S.T. Blake. The Government of Vietnam is carrying out a large-scale ‘reforestation’ programme, with the aim of improving local livelihood security, environmental sustainability and industrial wood supply. Smallholders are involved in plantation timber production through various schemes. Generally, these reforestation efforts have been effective, even though smallholders often lack the appropriate technical knowledge and management skills. Consequently, the quality and quantity of wood products may be suboptimal. The productivity of smallholder plantations can be improved by enhancing smallholders’ management knowledge and skills, including species selection (site matching), silvicultural management to produce high quality products, and pest and disease management.
