"Things are going wrong with our environment," writes John Terborgh, "even the parts of it that are nominally protected. If we wait until all the answers are in, we may find ourselves in a much worse predicament than if we had taken notice of the problem earlier. By waiting, one risks being too late; on the other hand, there can be no such thing as being too early." Terborgh's warnings are essential reading for all who care about migratory birds and our natural environment. Why are tropica...

For ecologist John Terborgh, Manu National Park in the rainforest of Peru is a second home; he has spent half of each of the past twenty-five years there conducting research. Like all parks, Manu is assumed to provide inviolate protection to nature. Yet even there, in one of the most remote corners of the planet, Terborgh has been witness to the relentless onslaught of civilization.Seeing the steady destruction of irreplaceable habitat has been a startling and disturbing experience...

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies.Trophic Cascades is the first comprehensive presentation of the science on this ...

Most scientists and researchers working in tropical areas are convinced that parks and protected areas are the only real hope for saving land and biodiversity in those regions. Rather than giving up on parks that are foundering, ways must be found to strengthen them, and Making Parks Work offers a vital contribution to that effort. Focusing on the "good news" -- success stories from the front lines and what lessons can be taken from those stories -- the book gathers experiences an...
