Invasive Predators Implicated in 738 Extinctions in 500 Years
Invasive predators have contributed to hundreds of extinctions. Island species are some of the most vulnerable to impacts from invasives.
A report in the Proceedings of the National Academy of Sciences, edited by Island Conservation Board Member Daniel Simberloff, sheds light on native wildlife deaths amassed by invasive predators. The New Zealand native Stephens Island Wren is just one of many examples of a species driven to extinction by invasives.
This extermination was not an isolated event. It has played out over and over again as invasive mammalian predators—cats, rodents, dogs, and pigs—arrive in new habitats and decimate native species.
When we lose all of these island species we’re potentially losing a lot of unique species forever that are found nowhere else.

Unless action is taken now, there could be many species whose value we won’t fully comprehend until they’re gone.
