Features almost 300 colour photographs and brings together more than 60 years of research by a leading voice in British woodland ecology. Trees define woodland. They provide a complex, multi-layered habitat for a great range of wildlife, yet they are wildlife themselves, reacting to their circumstances and each other. Woodlands are important to people, supplying timber, food and fuel, accumulating carbon, and offering places of refuge and refreshment. But they are also under threat: some stand in the way of 'progress' and all are becoming increasingly vulnerable to neglect, disease and climate change. Trees and Woodlands brings together decades of research to explore the ecology, nature conservation and wider cultural value of our native trees and shrubs, and the various ways they have combined as woodland. Incorporating personal experiences from 60 years as a forest ecologist, Peterken describes the long history of use and management; how this has influenced woodland wildlife and our art, beliefs and social attitudes. He concludes that most woods should be managed, their timber and small wood being put to good use, but recognises that this is all part of a larger question: the future of ourselves. Containing nearly 300 photographs, and interspersed with box texts describing the history and ecology of representative woods across Britain, this is a commentary on trees, woodlands and our relationship with them from one of our most highly regarded forest ecologists.
In 1944 Lady Park Wood (45 hectares of woodland in Gloucestershire and Monmouthshire, UK) was set aside indefinitely by the Forestry Commission so that ecologists could study how woodland develops naturally. Since then, in a unique long-term study, individual trees and shrubs have been recorded at intervals, accumulating a detailed record of more than 20,000 individual beech, sessile oak, ash, wych elm, small-leaved lime, large-leaved lime, birch, hazel, yew and other species. In the seven decades since the study started, the wood has changed; trees grew, died and regenerated, and drought, disease and other events shaped its destiny. Each tree and shrub species reacted in its own way to changes in the wood as a whole and to changes in the fortunes of its neighbours. Meanwhile, the wild fauna, flora and fungi also responded, leaving the wood richer in some groups but poorer in others. In this landmark book, beautifully illustrated throughout, George Peterken and Edward Mountford, summarise the ongoing results of the Lady Park Wood study, highlighting its unique place in nature conservation and its significance to ecology in general. It also builds on experience at Lady Park Wood and elsewhere to discuss in particular: the role and maintenance of long-term ecological studies; the concept and form of natural woodland; the role of minimum-intervention policies in woodland nature conservation; near-to-nature forestry; and the desirability and practicalities of re-wilding woodlands.
The second volume of a major new series of books on British natural history. Meadows provide one of the most wide-ranging and eloquent treatments of this most quintessential British habitat. Yet the flower-rich hay meadows that have inspired writers and artists for hundreds of years have almost disappeared from our countryside. In this exceptional work, George Peterken, one of our most respected ecologists, brings together years of research and discovery from his travels across Britain and Europe, as well as an understanding borne out of caring for his own meadows, to produce a book that will put this often misunderstood habitat back in the public's eye. Filled with beautiful images of meadows and their denizens, this is a book everyone with an interest in this iconic habitat will want to own.
A definitive natural history of the Wye Valley covering the geology, geomorphology, conservation and ecological history of this diverse area of outstanding natural beauty.

Temperate rivers are influenced by many factors including geology, climate, soils, sediment type, flow, as well as human activity. The complex interactions of the non-anthropogenic controlling factors have led to a wonderful diversity of river type throughout the British Isles. Sadly, almost all rivers in the UK have suffered significant and long-lasting modification by unsympathetic management, that has all but destroyed this variety, creating watercourses that are simplified conduits for water and sediment, designed primarily to drain the land and reduce flood risk. This volume aims to help reverse this, illustrating using over 200 images and descriptions, this variety of rivers in Britain, highlighting the many forms that temperate river systems take and providing an accessible summary of the underlying river science knowledge base. A Field Guide to British Rivers covers the full range of upland and lowland channel types and describes the full variety of substrate conditions from bedrock through boulder, cobble and gravel, to silt dominated systems. The authors describe examples gathered from their extensive research and practical experience working with rivers throughout mainland Britain and set those examples in their wider landscape context to exemplify the natural functioning of temperate river types. This book offers a practical and contextualised guide to contribute to efforts towards the sympathetic and sustainable restoration and re-naturalisation of degraded channels in the UK. Offering a unique viewpoint of both the underpinning science and the practicalities of river management, A Field Guide to British Rivers is an essential a stand-alone guide for anyone involved in river restoration and management as well as for those simply interested in rivers in general. Written as a field guide to demonstrate practical examples of river types, and to highlight the pressures they experience and their often-parlous condition, this book is intended to better inform both river management approaches and the policy necessary to achieve this. Fundamentally, the authors seek to demonstrate how the hydrological, geomorphological, and ecological functions of rivers and their catchments are inexorably intertwined, and together how they generate and maintain rivers as dynamic entities.

Professor John Harper, in his recent Population Biology of Plants (1977), made a comment and asked a question which effectively states the theme of this book. Noting that 'one of the consequences of the development of the theory of vegetational climax has been to guide the observer's mind forwards', i. e. that 'vegetation is interpreted as a stage on the way to something' , he commented that 'it might be more healthy and scientifically more sound to look more often backwards and search for the explanation of the present in the past, to explain systems in relation to their history rather than their goal'. He went on to contrast the 'disaster theory' of plant succession, which holds that communities are a response to the effects of past disasters, with the 'climax theory', that they are stages in the approach to a climax state, and then asked 'do we account most completely for the characteristics of a population by a knowledge of its history or of its destiny?' Had this question been put to R. S. Adamson, E. J. Salisbury, A. G. Tansley or A. S. Watt, who are amongst the giants of the first forty years of woodland ecology in Britain, their answer would surely have been that understanding lies in a knowledge of destiny. Whilst not unaware of the historical facts of British woodlands, they were preoccupied with ideas of natural succession and climax, and tended to interpret their observations in these terms.
