Managers of the Great Barrier Reef's (GBR) 900 islands face difficult decisions when it comes to investing in conservation management. Where should they invest limited funds to achieve the best outcomes? This project aims to address this problem by developing a decision making framework for investing cost-effectively in management actions across the GBR islands.

The broad goal is to work collaboratively with DERM and GBRMPA to develop an explicit decision-making framework for investing cost-effectively in management actions across the islands of the Great Barrier Reef. More specifically, the goal is to maximise a conservation outcome, defined by specific objectives for diverse natural features (eg. native plant and animal species, vegetation assemblages, breeding aggregations), in the face of spatially heterogeneous and dynamic threats, within a budget constraint, by applying a suite of actions that cost different amounts, and that contribute differently to objectives, under considerable uncertainty and the prospects of climate change. The problem - complex, dynamic and multifaceted - describes the reality of much conservation decision-making, and defines the problem faced by managers of the GBR's 900 islands.
