Is There a Humane Way to Deal With Invasive Animals? May 29, 2014

I read an article today ( about how the Chesapeake Bay Nutria Eradication Program is working well, and that the people involved in the program may actually succeed in removing all these large, invasive rodents from the Bay. It also mentions the success people have had with eradicating the invasive mute swan from the region. As someone who worked on invasive species issues for many years, albeit mostly related to plants, I applaud the efforts of these folks and am excited for their success story.

However, the animal lover in me cringes a little bit when I read articles like this, especially when they describe how the nutria are trapped and killed. The traps are similar to what people use to trap beavers for their pelts… the animal is snared by the leg and drowned. I’ve never agreed with how beavers are trapped, so I cannot agree with their use here, even if nutria are highly destructive to the wetland and marsh habitats they live in. There has to be a move humane way to do this.


Many animal rights activists oppose the culling of invasive animals on the grounds that the practice is inhumane. When looking at the issue from the 40,000 feet view, I disagree with them. Invasive species cause significant damage to habitats, in turn negatively affecting and sometimes killing other, native wildlife. Most invasives are here because of foolish or unintended consequences of human actions, so I feel that it is our duty to do something about them. But it’s how we do something about them that I may have an issue with. I used to be very opposed to herbicides, no matter what. I thought of them as a poison with which we contaminate the earth. Yet as I learned more through my job, I came to realize that sometimes herbicides are the only solution to eliminating certain invasive plant species. Herbicides shouldn’t ever be the only line of defense, and hopefully aren’t the first choice in many situations, but they do have their place.

So it is with invasive animal control. Think of the Burmese pythons that are taking over the Everglades. These are long, strong, animal eating machines. Should we just let them slither their way across the state of Florida? No, I don’t think so. The same goes for nutria, mute swans, feral hogs, snakehead fish, Asian carp, and a whole host of other invasive animal species in the U.S. Yet how we control these animals says a lot about how we treat animals in general. If someone has no problem drowning a beaver for its pelt, then of course they have no problem drowning a nuisance species by the same method. Changing this process will take considerable education.

How can we deal with the invasive species problem in a humane way? Better minds than mine will need to think about that. But I hope that someone is thinking about that. I certainly want the Chesapeake Bay to become a healthier, more productive ecology in the future, but I hope that can be achieved with less brutality in the future.
