Many species that are considered invasive in areas where they’ve been introduced may actually be threatened with extinction in their home ranges.
A new study published in Conservation Letters explores this conservation paradox, asking whether or not nonnative species that are endangered in their native range should be protected or controlled.
“We were interested in finding out how many of these species are threatened even in their native range,” said Lisa Tedeschi, the lead author of this study, in a press release.
Of the 230 nonnative mammals that have been introduced to new areas throughout the world, researchers found that 36 of them are threatened in their native ranges.
“We were very surprised by this high number, as we assumed that invasive species are also common in their area of origin,” Tedeschi said.
