More than a decade has passed since Professor Gisela Jahn completed Volume 12 of the Handbook of Vegetation Science, dealing with the application of vegetation science in forestry, mostly European forestry. The volume was well received by the critics with the exception that they wanted a more diversified demonstration of forestry-related vegetation science work and a wider representation of forest types from different continents. The topics covered in this volume, 12/1, widen the scope of vegetation science work in forestry over the phytosociological work which was the main focus in the Handbook as perceived by Dr Tuxen. Section 1. Overview T. Kira: Forest Ecosystems of East and Southeast Asia in a Global Perspective; E.O. Box: Climatic Relations of the Forests of East and Southeast Asia; K. Iwatsuki: Species Diversity in East Asia in Global Perspective. The remaining contributions are divided into the following sections: Evergreen Forest Region; Summergreen Forest Region; Montane/Boreal Region; Tropical Forest Region. "

This study arose out ofthe old question of what actually determines vegetation structure and distributions. Is climate the overriding control, as one would suppose from reading the more geographically oriented literature? Or is climate only incidental, as suggested by more site and/ or taxon-oriented writers? The question might be phrased more realistically: How much does climate control vegetation processes, structures, and distributions? It seemed to me, as an ambitious doctoral student, that one way to attempt an answer might be to try to predict world vegetation from climate alone and then compare the predicted results with actual vegetation patterns. If climatic data were sufficient to reproduce the world's actual vegetation patterns, then one could conclude that climate is the main control. This book represents an expanded, second-generation version of that original thesis. It presents world-scale vegetation and ecoclimatic models and a methodology for applying such models to predict vegetation and for evaluating model results. This approach also provides a means of geographical simulation of vegetation patterns and changes, which represent necessary data inputs in other fields such as atmospheric chemistry and biogeochemical cycling. It has been fairly well accepted that climatic and other environmental conditions are associated with the evolution of particular aspects of plant form (convergent evolution). The particular configurations of plant size, photosynthetic surface area and structure (e. g. sclerophylly, stomatal 'resistance'), and their seasonal variations represent what one can recognize fairly readily as distinct growth forms.
