RE: The nutria (Myocastor coypus) is invading Californian wetlands, and could cause havoc for this intricate ecosystem!
This seems to always end up happening with cash crop species. Cash may ultimately be the solution to the problem as well, incentivising the trapping and disposal of Nutria may be the only way to offset their impact.
Yeah, that's true. We need to be a lot more careful when we move species into new regions! I think the US already has a good routine with dealing with them, and they have apparently put up traps in the area already.
Here in Norway we often put up bounties on invasive species, which seem to work pretty good as well.
Bounties are typically the best way, but it has to be high enough to be worth the effort. Some species rebound to that as well as their breeding cycle goes into overdrive when their number thin out. Ultimately not letting them in into new habitats in the first place would be the best solution but that's probably unrealistic.
Absolutely! But it can also be very difficult to determine which species that are problematic before we find out the hard way. I would prefer it we completely stopped releasing new species into regions where they don't belong, but it seems like people are very interested in doing this for some reason..
Yeah, that is of course true. And then it boils down to whether or not the government can afford or justify using the money on bounties for killing animals instead of improving something else, and we get a whole political discussion going. The best solution would of course if it was possible to force the ones responsible for releasing the animal into the wild to pay for the bounties, but that seems unlikely.
