The Great Barrier Reef Marine Park (GBRMP) is the largest marine
protected area in the world. It is managed by the Great Barrier Reef
Marine Park Authority (GBRMPA) to provide for protection, wise use,
understandin,g and enjoyment in perpetuity through its care and
development. Knowledge of natural processes and the effects of humans
are critical to informed decision making and policy development. However,
the ability of science to resolve the cause and consequences of management
issues and guide management responses varies with the nature and scale of
the problem. It is important that scientists and managers alike recognize
that science is integral to good management, but frequently limited in its
contribution.
I examine three issues that have confronted the GBRMPA and explore the
role of science in their management: anchor damage, crown-of-thorns
starfish, and mass bleaching. These case studies illustrate that 1) scale
and interconnectivity preclude comprehensive knowledge of many components
of the GBR ecosystem; 2) the threats and issues that face such an
intricate system are themselves complex, and 3) not all issues are
amenable to management intervention. In addition, it is essential to
recognize that management is a socio-political process, so that management
of human interactions with the environment, and not the manipulation of
the environment itself, characterizes most management strategies. Science
rarely has all the answers, but its value will be maximized through an
understanding of the decision-making environment and a commitment to
interactivity and communication.
