Bibliography: leaves 108-113. This dissertation givens and analytical overview of the research and recovery actions for the Orange-bellied Parrot and the Kangaroo Island Glossy Black-Cockatoo and evaluates the successful practices and those which have failed. This research shows that new recovery action initiatives can still be found and that not all recommendations in recovery plans are followed, which impairs the efficiency of the recovery efforts. It concludes that a successful recovery effort of these two bird species lies in continued research, a serious compliance with the recommendations made by recovery plans and by further environmental education in society.
