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 subject. It brings together some of the world's leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.
