The author argues that Rhodesia's wildlife is in serious danger owing to poor or inadequate management in the national parks and reserves. He traces the stages leading up to the biological collapse of a habitat, which he says has already happened with the Tuli Circle National Land, and suggests that knowledge gained from game ranching and a new method of domestic stock management on privately owned lands has pointed the way for the future. Mr Savory is a consultant ecologist and his views are controversial, but the FPS believes that they merit serious consideration and should be heard.
