Hi James
The question of what to do with Polar Bears in Iceland has been discussed frequently here, with repatriation as one of the options. True, it would be a great publicity stunt (let's face it, it's not a conservation issue - hundreds of Polar Bears are shot legally every year across the Arctic, mainly in Canada - so the odd animal in Iceland is fairly insignificant). But it is easier to raise awareness with the help of an iconic animal like a Polar Bear (there was certainly no clamour to repatriate the vulnerable Cerulean Warbler when that showed up in 1997!).
So how do you repatriate a Polar Bear? I'm not sure, but I bet it's not as easy as it looks on Animal Planet. You'd need a team of people who know what they are doing to be ready to mobilise at short notice as you ideally don't want to leave a Polar Bear wandering around on its own for too long - Iceland might be the most sparsely populated country in Europe but it's very crowded compared with East Greenland.
I doubt tranquilising one is straightforward as you'd have to ensure it's reasonably far from water so it doesn't make a break for the safety of the sea or a lake and drown, a not unlikely scenario seeing as most records are coastal. If you do successfully knock it out, then what next? Polar Bears that reach Iceland have usually been swimming a long way and are often in bad shape. Is there anybody in Iceland qualified to nurse a starving and injured (they often have badly damaged front paws from swimming) bear back to health while it awaits repatriation? I sincerely doubt it.
But with money some of these problems could probably be surmounted and it might be possible to raise this money internationally - Iceland certainly doesn't have cash for this kind of thing. But as it is of zero conservation value, wouldn't such resources be better put into reclaiming wetlands, preserving moorlands and ensuring that no more mudflats disappear to land reclaimation schemes? Iceland is important for its vast wader and wildfowl populations, the odd Polar Bear is really neither here nor there.
When the bears turned up in 2008, one of the world's leading Polar Bear biologists was asked his opinion on a rescue. His answer was that any rescue attempt would be a ridiculous waste of money. Sadly, I'm inclined to agree.
