Deciduous forests have been remarkably resilient throughout their history, recovering from major shifts in climate and surviving periods of massive deforestation. But today the world’s great forests confront more ominous threats than ever before. This visionary book is the first to examine forests consisting of oaks, maples, hickories, beeches, chestnuts, birches and ecologically similar animals and plants on three continents—East Asia, Europe, and North America—to reveal their common origin back in time, the ecological patterns they share, and the approaches to conservation that have been attempted on their behalf. Although these forests face common problems, threats due to human activities vary. Different land use and agricultural practices on the three continents, as well as different attitudes about what is worth preserving, have led to strikingly different approaches to forest conservation. Robert Askins explores the strengths and weaknesses of conservation efforts across the continents and concludes that the ideal strategy for the future will blend the best ideas from each.
DIVThe decline of bird species in a wide range of North American habitats—forests, prairies, shrublands, mountain regions, marshes, and deserts—has inspired two decades of intense scientific study of bird ecology and conservation. But for professional scientists and amateur birders alike, interpreting the results of these diverse studies is often complex and bewildering. This accessible book pulls together recent research on bird species and habitats to show how basic ecological principles apply in seemingly different situations. Robert A. Askins provides an engaging introduction to bird ecology and concepts of landscape ecology, focusing on such intriguing species as Bachman’s Warbler, Red Crossbill, Mountain Plover, and Marbled Murrelet. Understanding the ancient landscapes of North America and how humans have changed them, Askins says, is essential for devising plans to protect and restore bird populations. In addition to such obvious changes to the landscape as the clearing of forests and plowing of prairies, more subtle changes also dramatically affect birds. Species may disappear when we interrupt natural disturbances by suppressing wildfires or trapping out beaver, or when we disrupt habitat with roads and housing developments. Askins challenges some of the assumptions that underlie current conservation efforts and offers concrete recommendations, based on sound ecological principles, for protecting the rich natural diversity of North America’s birds./div
