Trees and woods offer great potential for rebuilding our wider relationship with nature, reinforcing local identity and sustaining wildlife. We need more trees and woods in our lives, to lock up carbon, to mitigate flooding, to help shade our towns and cities and bring shelter, wildlife and beauty to places. Living with Trees is a cornucopia of practical information, good examples and new ideas that will inspire, guide and encourage people to reconnect with the trees and woods in their community, so we can all discover how to value, celebrate and protect our arboreal neighbours.

This thorough and meticulous study, the result of nearly a quarter-century of research, examines the island biogeography of plants on continental islands in Barkley Sound, British Columbia. Invaluable both because of its geographical setting and because of the duration of the study, Plants on Islands summarizes the diversity, dynamics, and distribution of the approximately three hundred species of plants on more than two hundred islands. Martin Cody uses his extensive data set to test various aspects of island biogeographic theory. His thoughtful analysis, constrained by taxon and region, elucidates and enhances the understanding of the biogeographic patterns and dynamics. He provides an overview of the basic theory, concepts, and analytical tools of island biogeography. Also discussed are island relaxation to lower equilibrium species numbers post-isolation, plant distributions variously limited by island area, isolation and climatic differences, adaptation to local abiotic and biotic environments within islands, and the evolution of different island phenotypes. The book concludes with a valuable consideration of equilibrium concepts and of the interplay of coexistence and competition. Certain to challenge, Plants on Islands is among the first books to critically analyze the central tenets of the theory of island biogeography.

There is currently much concern about our trees and woodlands. The terrible toll taken by Dutch elm disease has been followed by a string of further epidemics, most worryingly ash chalara - and there are more threats on the horizon. There is also a widely shared belief that our woods have been steadily disappearing over recent decades, either replanted with alien conifers or destroyed entirely in order to make way for farmland or development. But the present state of our trees needs to be examined critically, and from an historical as much as from a scientific perspective. For English tree populations have long been highly unnatural in character, shaped by economic and social as much as by environmental factors. In reality, the recent history of trees and woods in England is more complex and less negative than we often assume and any narrative of decline and loss is overly simplistic. The numbers of trees and the extent and character of woodland have been in a state of flux for centuries. Research leaves no doubt, moreover, that arboreal ill health is nothing new. Levels of disease are certainly increasing but this is as much a consequence of changes in the way we treat trees - especially the decline in intensive management which has occurred over the last century and a half - as it is of the arrival of new diseases. And man, not nature, has shaped the essential character of rural tree populations, ensuring their dominance by just a few indigenous species and thus rendering them peculiarly vulnerable to invasive pests and diseases. The messages from history are clear: we can and should plant our landscape with a wider palette, providing greater resilience in the face of future pathogens; and the most `unnatural' and rigorously managed tree populations are also the healthiest. The results of an ambitious research project are here shaped into a richly detailed survey of English arboriculture over the last four centuries. Trees in England will be essential reading not only for landscape historians but also for natural scientists, foresters and all those interested in the future of the countryside. Only by understanding the essentially human history of our trees and woods can we hope to protect and enhance them.

The floristic diversity in southern Africa is not only one of the region's greatest natural assets, but also one of the botanical wonders of the world. Here, South of the Cunene-Zambezi rivers, more than 10% of all vascular plants (over 30,000 species), including more than 46% of all succulents, are found on about 2.5% of the world's land surface area. Moreover, at least 60% of these species are strictly confined (endemic) to the region.;It is remarkable that most of southern Africa's endemic plants are concentrated in only a few relatively small and well demarcated areas known as Regions or Centres of Endemism. Although the existence of these centres has been known to field botanists for a long time, most of them remain comparatively unknown outside scientific circles. Over many years, the authors of this work have carefully documented the diversity of endemic plants and here they present the results of their efforts to recognize and define areas that warrant status as "centres of endemism".;Contrary to what would be expected from a botanically rich region, large parts of southern Africa are subjected to regular and almost predictive droughts, prolonged periods of below-average rainfall and a marked seasonality in precipitation. One consequence of the general aridity of the region has been the development of succulence as a survival strategy in many plants, including a significant proportion of endemics. In addition, many of these fat-bodied plants have acquired distinct defence mechanisms that enable them to survive in this harsh and often inhospitable climate. The resultant peculiar forms and behaviour patterns of these plants have fascinated botanists, plant explorers and the general public for years.;Whereas the classification and mapping of southern Africa's vegetation types have been the subject of numerous publications, the classification and mapping of the distribution patterns of the region's plant species have been neglected. This study brings together all the relevant information on most of the principal Regions and local Centres of Plant Endemism in southern Africa.

Half of the ancient woodlands present in 1945 have been destroyed, replanted with conifers or cleared for cereal production, roads and building development. The intention of this book is to present evidence of our deep cultural need for trees and woods and to inspire people to take care of them. Trees, and indeed woods, know no distinction between town and country; they are close to everyone. If we are to combat local pollution, make even the slightest impact on global warming, enjoy our surroundings and share them with many other creatures, we need trees: trees here and trees now. If we are to nourish more than our prosaic needs we need their longevity, their beauty, their generosity. Trees stand for nature and culture. We shall stand or fall with them.

Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things. Tree explores the forms, uses, and alliances of this living object's entanglement with humanity, from antiquity to the present. Trees tower over us and yet fade into background. Their lifespan outstrips ours, and yet their wisdom remains inscrutable, treasured up in the heartwood. They serve us in many ways-as keel, lodgepole, and execution site-and yet to become human, we had to come down from their limbs. In this book Matthew Battles follows the tree's branches across art, poetry, and landscape, marking the edges of imagination with wildness and shadow. Object Lessons is published in partnership with an essay series in The Atlantic.

Where mountains meet ocean in Alaska's Alexander Archipelago, white skeletons of dead yellow cedar trees stand prominently amidst a verdant landscape of old-growth forests. Researchers spent nearly three decades deciphering the cause of the majestic species' death and uncovering climate change as the culprit. Lauren E. Oakes, a young scientist at Stanford University, was one of them. But even as she set to record the demise of a species, she soon found herself immersed in an even bigger, and totally unexpected, story: how the people of Alaska were adapting to the tree's disappearance, and how the tree itself, seemingly doomed, was adapting to a changing world. In Search of the Canary Tree is the story of six years that Oakes and her team spent in the Alaskan wilds, studying thousands of trees and saplings along the archipelago of southeast Alaska. Far from losing faith in the survival of our woodlands, she discovered the resiliency of forgotten forests, flourishing again after years of destruction and decomposition. And, through deep encounters with loggers, naturalists, Native weavers, and enthusiasts of the yellow cedar, Oakes discovered how the people of Alaska were determined to develop new relationships with the emerging environment. Where many scientists and commentators have found in climate change an unmitigated disaster, Oakes found beacons of hope even in the disorienting death of a species. Above all else, Oakes shows us that, although we can respond to climate change with either fear or denial, we can also find in it a new world, and one that doesn't necessarily have to be for the worst. Eloquent, insightful, and deeply heartening, In Search of the Canary Tree shows how human and natural resilience can help preserve ourselves, even in our rapidly changing world.
