'In Clive, we have an ever-fascinating guide to Britain's heathery districts, not only marvelling at the wildlife of such wild places, but also celebrating their diverse origins, uses and cultural resonances' - ANDREW BYFIELD Heathlands are so much more than simply purple carpets of heather. They are ancient landscapes found throughout Britain that support a complex of inter-related species and an immense diversity of habitats. They also possess a unique human history defined by the struggle between pastoralism and the competing demands of those who seek exclusive use of the land. In this latest addition to the British Wildlife Collection, Clive Chatters introduces us to Britain's heathlands and their anatomy. He then takes the reader on a geographical heathland tour – from the maritime sub-arctic of the Shetlands to the mild wetness of the Atlantic coast – with an in memoriam nod to those heaths that have been erased from common memory and understanding. He concludes with a review of how people have perceived and used heathland wildlife over the ages, and sets out a future vision for this iconic landscape, its unique habitats and the species that live there. Most of our heaths are pale shadows of their former selves. However, Chatters argues, it is not inevitable that the catastrophic losses of the recent past are the destiny of our remaining heaths. Should we wish, their place in the countryside as an integral part of British culture can be secured.

The theory of ecological convergence underlies the biogeographers' maps of world biome-types. It also determines the degree to which ecological principles, derived from research on particular populations, communities or ecosystems, are generally valid, and hence also to what extent resource management principles are general. To quote Di Castri and Mooney (1973): "In effect, in order to assess the transfer of technology, it is essential to know to what extent information acquired from studying one particular ecosystem is applicable to another ecosystem of the same type but situated in a different location. " The five relatively small, isolated, mediterranean-climate zones of the earth, each with its distinct fauna and flora, have provided the ideal testing grounds for this theory. A heritage of precisely focused ecosystems research has resulted, beginning with the international comparative analyses conducted by Specht (l969a, b) but with antecedents in earlier studies in South Australia (Specht and Rayson 1957, Specht 1973). Cody and Mooney (1978) reviewed the information available at the time for the four zones excepting Australia and concluded that the arrays of strategy-types to be found among the different biotas were so similar that they could be explained only in terms of the convergence hypothesis; nevertheless, evident differences in community organization and dynamics, especially phenol ogy, required closer study of resource availability and resource-use patterns to better explain relations between form and function overall, and to assess the degree of convergence at higher levels of organization than the population.
