ANCHORAGE, Alaska (Reuters) - Two centuries after rats first landed on a remote Aleutian island from a shipwreck, wildlife managers in Alaska are plotting how to evict the non-native rodent from the island that bears their name.
Rat Island, like many other treeless, volcanic islands in the 1,000-mile (1,609-km) long Aleutian chain, is infested with rats that have proved devastating to wild birds that build nests in the earth or in rocky cliffs.
"They pretty much made the island worthless for a lot of wildlife," said Art Sowls, a biologist with the Alaska Maritime National Wildlife Refuge, which sprawls across the Aleutians and other Alaska islands.
Rodents have reigned at Rat Island at the western end of the Aleutians since the 1780 shipwreck of a Japanese sailing ship, wreaking havoc on millions of seabirds with no natural defenses against land predators.
