Australia holds custodianship of one of the most diverse sets of island landscapes of any country. These range from the sub-Antarctic (Heard and Macquarie Island) and include oceanic islands (such as the exposed sea-mounts that form Lord Howe and Norfolk), sea stacks and temperate islands, tropical atolls (Keeling), continental islands and coral cays. Islands represent only 0.0042% of Australia’s landmass, but form 40% of its coastline (Geosciences Australia, 2013). Islands under Australian stewardship number around 8,200. These are repositories for a staggering amount of Australia’s biological diversity. For example, 30% of all Australia’s threatened fauna are island inhabitants. What is of critical importance here is that only on islands can key threatening processes, such as presence of feral animals, be cost effectively eliminated. Further, robust bio-security arrangements could prevent island incursions by the feral animals, weeds and diseases that continue to ravage biological diversity on mainland Australia. It is important also to consider that islands play a very large role in human society. For example, islands form the foundation of an estimated $13 billion/annum nature based tourism industry.
Island Arks Australia
Despite their demonstrably critical importance to the conservation of Australia’s biological diversity and regional economies; islands have never received a commensurate amount of management attention. Co-operative research centers and aligned management efforts have been formed for numerous other landscapes; coral reefs, rainforests, deserts, Antarctic and savannahs but not islands. Islands are also overlooked within protected area systems. For example, nationally, less than 30% of islands are protected within Nature Reserves (Taylor, 2010). The purpose of Island Arks Australia is to initiate and/or assist and/or develop partnerships across Australia that would improve the sustainability of island environments, communities and economies. The ‘State of Australia’s Islands’ report is a key initiative that will help island communities, managers, users and decision makers understand the current status of Australia’s island, their management challenges, and the opportunities that exist to make best use of these iconic landscapes.’
The State of Australia’s Islands
The State of Australia’s Island report is in two parts. One, a synopsis of what is known about islands on a state and territory basis. Key sections include geography, tenure and jurisdictional arrangements, geographically related marine protected areas, key conservation values, community and people, current condition, threats and information sources. Two, a selection of case studies that highlight what is possible when well-designed management interventions are undertaken in partnership with island communities. The State of Australia’s Island report will grow and change over time. The intention is that updates will be regularly made as new information becomes available, and new and better management interventions are undertaken. All islanders, island managers and visitors are welcome to be involved.
