Are We Managing Invasive Species Wrong?

New research suggests that sometimes trying to completely eliminate a problematic non-native species may cause more harm than good.
European green crabs arrived on the eastern shores of North America in the early 1800s, likely as ship ballast stowaways or affixed to boat hulls. They found their way to the continent’s western shores by the 1980s, and they’ve caused trouble in every new ecosystem they invade.

Wherever green crabs (
Carcinus maenas) land, scientists have documented them decimating food webs by devouring benthic invertebrates that provide nourishment for shorebirds, fishes and other species. Over the years, they have eaten their way onto a list of the world’s top 100 most unwanted species. ....

While surveying the Hawaiian island of Kauai in search of invasive plants in 2017, botanist Kelsey Brock spotted something unusal: a few nonnative species of figs seemed to be settling in.
As people traverse the planet for trade or travel, they bring a slew of species with them, many of which establish a foothold in a new place and may eventually replace the local native species. But because of a quirk of fig biology, my colleagues and I wondered how these figs could be reproducing to form new populations on Kauai. ....
