WHY IS THIS RESEARCH NEEDED?
In the last decade, many papers and policy documents have put forth guidelines that have emphasised the need to incorporate ecological patterns of connectivity in marine protected area network design. However in the context of conservation planning, connectivity has been poorly defined, and guidelines have focused on providing broad “rules of thumb”, as opposed to specific, quantitative recommendations.
Despite increased knowledge of the extent of larval dispersal in recent years, connectivity remains a major knowledge gap in designing marine protected area networks. Explicit consideration of connectivity processes in marine conservation planning has been impeded by a paucity of empirical data, and a lack of specific, quantitative objectives.
New empirical data, acquired through novel techniques such as genetic parentage analysis, have advanced our understanding of complex ecological connectivity processes, and the spatial scales across which they need to be managed. We are now in a position to advance conservation planning theory and develop new tools for spatial conservation prioritisation that move beyond ensuring representation of static biodiversity features (e.g., species and habitats), to also consider dynamic connectivity processes.
HOW WILL THIS RESEARCH HELP?
The effective design of marine protected area networks requires an understanding of connectivity processes in order to inform decisions about the size, spacing and location of reserves. This research will provide important insights and tools to guide conservation practitioners faced with making these decisions.
Our research will develop new theories of how to use information on larval dispersal and population connectivity to inform marine protected area network design. We will develop spatial optimisation and prioritisation tools capable of explicitly targeting dynamic connectivity processes, and apply these in regions where empirical connectivity data is emerging. These new tools will be then be used to test the efficacy of existing rules of thumb in achieving quantitative, ecologically informed objectives. This will provide information on the value of empirical connectivity data, and help to refine rules of thumb for the many areas where such data are lacking.
This project began in February 2013, and is ongoing. Anticipated research outputs include:
WHERE IS THE RESEARCH HAPPENING?
This research builds upon empirical and modeling work undertaken in the Keppel Islands, Australia; Kimbe Bay, Papua New Guinea; the Bohol Sea, Philippines; Brazil and the Coral Triangle.
