Book excerpt: Few, if any, environments are free of human intervention. Often this generates ecosystems which are rich in biodiversity, historical interest, recreational opportunity and scenic beauty just as worthy of conservation as the more natural ecosystems on which protection programmes have been almost exclusively focussed. These 'cultural landscapes', ranging from the farm and forest lands of Europe and Eastern North America, through to the pasture lands and savannas of the Middle East and Africa to the paddylands of the Pacific Rim, are usually the product of relatively low-level, sustainable exploitation of the environment over long periods of time. Many have survived for centuries, if not millennia, but now urban expansion, depopulation of rural areas and, most damagingly, the intensification of agricultural and sylvicultural practices, are everywhere leading to a loss of their cherished biodiversity and amenity. Whilst past changes have mostly added to the valued characteristics of these landscapes, modern farming and forestry are creating sterile monocultures on the better land whilst marginal lands are being abandoned. This book documents these changes, illustrates them through detailed case studies of a representative selection of threatened landscapes, analyses their underlying causes and explores ways by which they can continue to be maintained, or new landscapes created which maintain their desired characteristics.

Available in PDF, EPUB and Kindle. Book excerpt: Habitat loss and degradation that comes as a result of human activity is the single biggest threat to biodiversity in the world today. Habitat Fragmentation and Landscape Change is a groundbreaking work that brings together a wealth of information from a wide range of sources to define the ecological problems caused by landscape change and to highlight the relationships among landscape change, habitat fragmentation, and biodiversity conservation. The book: synthesizes a large body of information from the scientific literature considers key theoretical principles for examining and predicting effects examines the range of effects that can arise explores ways of mitigating impacts reviews approaches to studying the problem discusses knowledge gaps and future areas for research and management Habitat Fragmentation and Landscape Change offers a unique mix of theoretical and practical information, outlining general principles and approaches and illustrating those principles with case studies from around the world. It represents a definitive overview and synthesis on the full range of topics that fall under the widely used but often vaguely defined term "habitat fragmentation."

Book excerpt: Wetlands occupy some six per cent of the Earth's land surface. They vary from fens and freshwater marshes to tropical mangroves and tundra swamps. They perform vital hydrological, chemical and biological roles and contain unique and diverse forms of wildlife and habitat. They are disappearing at an alarming rate and are threatened by both the direct and indirect effects of human activity. The purpose of this book of especially commissioned articles is threefold: (a) to explore the occurrence and composition of wetlands and their physical and biological dynamics; (b) to consider the impact upon them of agriculture, industry, urbanisation and recreation; and (c) to examine what steps can be taken to manage and to preserve their future survival.

Available in PDF, EPUB and Kindle. Book excerpt: Queensland is home to 70% of Australia's native mammals (226 species), over 70% of native birds (630 species), just over half of the nation's native reptiles (485) and native frogs (127), and more than 11,000 native plant species. Hundreds of these have a threatened status. In order for Queensland to maintain and recover a healthy biodiversity, Australians must address the serious problems faced by their natural environment - habitat loss, inappropriate land management, change in fire regimes, pollution of natural resources, proliferation of invasive species and climate change. This comprehensive and practical guide to Queensland's threatened animals features up-to-date distribution data, photos and maps for most of Queensland's threatened animals. KEY FEATURES * Includes up-to-date distribution data, photos and maps * Includes a comprehensive list of resources, with key state, national and international organizations involved in the recovery of threatened species * Complemented by an open access website that will be updated on a regular basis

Available in PDF, EPUB and Kindle. Book excerpt: In the United States and Canada, thousands of species of native plants are edging toward the brink of extinction, and they are doing so quietly. They are slipping away inconspicuously from settings as diverse as backyards and protected lands. The factors that have contributed to their disappearance are varied and complex, but the consequences of their loss are immeasurable. With extensive histories of a cast of familiar and rare North American plants, The Quiet Extinction explores the reasons why many of our native plants are disappearing. Curious minds will find a desperate struggle for existence waged by these plants and discover the great environmental impacts that could come if the struggle continues. Kara Rogers relates the stories of some of North America’s most inspiring rare and threatened plants. She explores, as never before, their significance to the continent’s natural heritage, capturing the excitement of their discovery, the tragedy that has come to define their existence, and the remarkable efforts underway to save them. Accompanied by illustrations created by the author and packed with absorbing detail, The Quiet Extinction offers a compelling and refreshing perspective of rare and threatened plants and their relationship with the land and its people.
