Bøger af Günther Bloch

Now available in paperback, this compelling book is full of behavioural insights and wolf tales that will engage those interested in the state of wild wolves throughout North America.In the winter of 2008¿09, a new wolf family from the Pipestone Valley suddenly appeared in the Bow Valley of Banff National Park, taking up residence alongside a family that had ruled there for over a decade. Within a year, these new wolves had eliminated the Bow Valley wolves and established a dominance that would last for five years in the heart of Canadäs most famous national park.The book chronicles not only the rise of the Pipestones and how they established and maintained dominance in the valley, but also how an increase in mass tourism in Banff led to a decrease in prey density for the Pipestones, which in turn led to the wolves changing their hunting strategies and expanding their summer range. Bloch explains how the Pipestones faced an inevitable fall from the top as pressure from eager wolf watchers increased exponentially in the park at the same time the wolves¿ prey base was shrinking rapidly. Combining these influences with other factors like rail mortality and old age, Bloch and Marriott knew the end was near for the Pipestones.The authors conclude with insights into how wolf and wildlife management in Banff National Park can improve. They outline steps Parks Canada should be taking to deal with the human management problems that are really at the core of the wildlife issues in the park. They also discuss whether we can continue to maintain a balance between ecological integrity and mass tourism in Canadäs flagship park and whether it is already too late. Have we passed the point of no return? And will our Banff wolves live forever after in a wildlife ghetto devoid of true wilderness characteristics?
