On 23 March 2015 the final load was dropped in Phase 3 of the Habitat Restoration Project. The entire island of South Georgia, all 100,000 hectares of rodent-infested land, had been treated with the bait which would remove the invasive rats and mice. In a matter of days South Georgia could be rodent-free for the first time in almost two centuries. Its birds would finally be free of the predator that had devastated their nests and chicks, and threatened entire species with extinction.Over time, prions, petrels, pintails and pipits will re-colonise their abandoned nesting sites, increasing the seabird population on the island by an estimated 100 million.
