Evidence-based conservation advocacy can work

Colin ‘Captain Hook’ Barnett

Just before knock-off time last Friday, I received some inspiring news. It’s not often in conservation science that the news is good, so even small wins are deliciously welcome.

Unless you’ve been out bush for the last few days or completely ignored the news services, you would have heard that Western Australia has decided not to go ahead with its moronic shark-culling programme. It all came down to the Western Australia Environmental Protection Authority‘s recommendation to the state government that it should not proceed with the cull because of ‘uncertainties’ in its effectiveness and impacts. While the government could conceivably ignore this recommendation and go ahead with the cull anyway, the right-wing Premier of Western Australia, Colin ‘Captain Hook’ Barnett, stated that while he was “disappointed”, the government was unlikely to appeal the decision, at least this year.

Putting the obvious commentary on his response aside for the moment, this is a rare example where overwhelming evidence actually persuaded a semi-autonomous government agency from going ahead with clearly stupid environmental policies. I can claim a small part in this endeavour, having co-written the synopsis of the scientific consensus statement and co-signed the submission to the Environmental Protection Authority. However, it was mainly down to the hard work and dedication of Professor Jessica Meeuwig of the University of Western Australia that the Western Australia government had little choice to but to heed our condemnation. Without her, I can pretty much guarantee that the shark slaughter would be continuing this year.

As they say in France, “chapeau” to Jessica. Read the rest of this entry »





Colour-blind sharks

3 02 2011

A few weeks ago I was interviewed on Channel 10 (Adelaide) about some new research coming out of the University of Western Australia regarding shark colour vision.

I’ve received permission from Channel 1o to reproduce the news snippet here. The first bloke interviewed is Associate Professor Nathan Hart, the study‘s lead author. I’m the bald one appearing in the middle at at the end.

It certainly was an interesting story, although two claims were made that probably needed better contextualisation.

First, the authors claim that because of this taxon’s colour blindness, they probably notice pigment transitions more when using visual cues to identify potential prey. What this means is that bright colours set against duller backgrounds might provide that contrast enough to attract sharks. The upshot from the interview is that brightly coloured and patterned togs (bathers) might make sharks think you are potentially a tasty treat. Read the rest of this entry »
