Tree Crop Ecosystems is a unique new resource which combines the interests of traditional foresters and horticulturalists. Sixteen chapters written by international experts in the field emphasise the current topical issues besetting each of the crops considered. In the past the management of tree crops was focussed on yield without an adequate understanding of crop behaviour. Recent decades have seen many major advances in knowledge, notably those related tree biology and biodiversity within species and between different crops. Throughout the volume the issue of biodiversity is discussed as a key factor in relation to: the conservation of natural resources at risk; within species variation; and the flora and fauna associated with tree crops. Tree Crop Ecosystems is unique in taking an holistic approach to the crops, their origins and within-species variation. Direct and indirect influences of the crops on their ecosystem are considered throughout the volume. Genetic resources of these crops as well as their pests and pathogens are also included. The case studies presented in Tree Crop Ecosystems harness the most recent advances in knowledge and consider their value in practical resource management. Eleven of the sixteen chapters in this volume are concerned with the management of specific crops (temperate and tropical conifers and broad-leaves with an emphasis on eucalypts and conifers; tea, coffee, palms, apple and rubber). The remaining chapters focus on multipurpose trees, the complex of minor species and environmental influences.
