This document discusses climate change adaptation and multilevel governance in the Great Barrier Reef. It outlines that the Great Barrier Reef is at major threat from climate change and describes adaptation strategies undertaken at different levels of government. These include information and research, policies, plans and programs, legislation, tools and guidelines, and networks. Adaptation can be purposeful in response to climate change impacts, marine park management, legislation, natural resource management, and planning. Adaptation is triggered by experiences of climate change impacts, marine park management strategies, legislation, and natural resource management issues. Adaptation in the Great Barrier Reef involves interplay between the federal, state, and local levels of government through both horizontal and vertical interactions.
