A few weeks back I cosigned a ‘statement of concern’ about the proposal for Australia’s South West Marine Region organised by Hugh Possingham. The support has been overwhelming by Australia’s marine science community (see list of supporting scientists below). I’ve reproduced the letter addressed to the Australian government – distribute far and wide if you give more than a shit about the state of our marine environment (and the economies it supports). Basically, the proposed parks are merely a settlement between government and industry where nothing of importance is really being protected. The parks are just the leftovers industry doesn’t want. No way to ensure the long-term viability of our seas.
On 5 May 2011 the Australian Government released a draft proposal for a network of marine reserves in the Commonwealth waters of the South West bioregional marine planning region.
Australia’s South West is of global significance for marine life because it is a temperate region with an exceptionally high proportion of endemic species – species found nowhere else in the world.
Important industries, such as tourism and fisheries, depend on healthy marine ecosystems and the services they provide. Networks of protected areas, with large fully protected core zones, are essential to maintain healthy ecosystems over the long-term – complemented by responsible fisheries management1.
The selection and establishment of marine reserves should rest on a strong scientific foundation. We are greatly concerned that what is currently proposed in the Draft South West Plan is not based on the three core science principles of reserve network design: comprehensiveness, adequacy and representation. These principles have been adopted by Australia for establishing our National Reserve System and are recognized internationally2.
Specifically, the draft plan fails on the most basic test of protecting a representative selection of habitats within the bioregions of the south-west. There are no highly protected areas proposed at all in three of the seven marine bioregions lying on the continental shelf3. Overall less than 3.5% of the shelf, where resource use and biodiversity values are most intense, is highly protected. Further, six of the seven highly protected areas that are proposed on the shelf are small (< 20 km in width)4 and all are separated by large distances (> 200 km)5. The ability of such small isolated areas to maintain connectivity and fulfil the goal of protecting Australia’s marine biodiversity is limited. Read the rest of this entry »
