Moving species to save them is quickly gaining traction as climate change upends habitats. But concerns persist that the novel practice could cause unintended harm the same way invasive plants and animals have wreaked havoc on native species.
But for the Tristram’s storm petrels on northeastern Hawaii’s Tern Island, which is just 6 feet above sea level, the relocation of about 40 chicks to artificial burrows more than 500 miles away on Oahu could offer new hope. The species is considered vulnerable to extinction, and the goal is for the young petrels return to their new home when old enough to breed.
A pending change to the U.S. Endangered Species Act by the Biden administration would make it easier to relocate some of the most imperiled species to places where they’ve not previously been recorded. Republicans in western states — including Montana, New Mexico and Arizona — are against the proposal saying it could wreak ecological havoc as “invasive species” get purposefully introduced.
The issue goes beyond endangered species, McLachlan said, and raises questions about what should be considered “native” now that shifting temperatures are pushing some species to higher elevations or toward the planet’s poles.
