This is a book about ecosystems: the ways in which we perceive them, conceptualize them, protect them, and manipulate them. Ecosystems have been given considerable attention in recent literature, and with good reason. Our growing comprehension of irreplaceable and imperiled ecosystem services has made it clear that we are in the midst of an ecological crisis.§In response, various organizations, agencies, and individuals have dedicated themselves to the preservation, restoration, and maintenance of ecological systems. The United States is a world leader in this regard, building upon the legacy of giants like Thoreau, Muir, and Leopold.§And yet, even as we scramble to rehabilitate and sustain ecosystems, the debate on their nature continues. In one corner are proponents of holism those that see ecosystems as definable units with recognizable and regenerative stable states.
