The removal of a top carnivore from an ecosystem can have an impact on the relative abundance of herbivore species . . . In the absence of predators, usually one or two herbivore species come to dominate the community. The consequence is often a direct alteration of herbaceous vegetation near to the base of the food web. Top carnivores have an important role to play in the structuring of communities and ultimately of ecosystems. Thus, the preservation of carnivores becomes an important consideration in the discipline of conservation biology” Dr. John F. Eisenberg
