Louisiana wetlands, as many places, are the inadvertent home to some ecosystem-altering invasive species, like fast-spreading aquatic plants called water hyacinth and giant salvinia. But hippos, no. There aren’t any hippos down there.
Oh, what might have been.
I’m not sure how I didn’t discover this earlier, considering how much I’ve been writing about invasive species of late—things like zebra mussels and sea lamprey in the Great Lakes and snakes on Guam and cheat grass in the American West, to name a diverse few. But miss it I did, until recently. Now I know that some people, partly in the name of invasive-species control, once considered bringing hippopotamuses from Africa to Louisiana and setting them free.
It was the early 20th century and it was going to be a great thing, because hippos would offer a tasty new resource for a meat-hungry and fast-growing nation and, bonus, they’d help control those pesky aquatic greens that were swallowing up swaths of wetland that normally support young fish, ducks, and a lot of other desirable creatures. A win-win.
