SANTA CRUZ ISLAND, Calif. Norm Macdonald rises each
morning with the sun, grabs his .223-caliber rifle and slips into
the passenger seat of a tiny, doorless helicopter for another day
of shooting pigs.
As the chopper skims over rugged terrain, Macdonald scans dozens
of simple fence traps he's set up for the thousands of wild swine
that have overrun this Southern California island.
When there are pigs in the traps and there always are
Macdonald leans out and pumps two bullets into each animal: One for
the heart and one for the head.
Each pig's death brings conservationists one step closer to
their goal of saving the tiny Santa Cruz fox, an endangered species
found only on this 96-square-mile island off Santa Barbara. Experts
believe it's the best way to mend the island's delicate ecological
web, which was torn when domesticated pigs escaped from
now-abandoned ranches as early as the 1850s.
The killings have angered animal rights groups and forced the
National Park Service and The Nature Conservancy, which co-own the
island, to explain why groups dedicated to protecting animals are
instead paying $5 million to kill them.
"It's not just about killing pigs, it's about saving a native
species," says Lotus Vermeer, the conservancy's project director
for Santa Cruz Island. "What we're choosing to do here is save
Macdonald and his eight-man hunting team from the New
Zealand-based Prohunt Inc. have started fast killing in the past
two weeks more than 800 of the island's estimated 3,000 pigs. They
expect the entire process to take more than two years, eventually
incorporating trained dogs, infrared sensing devices and radio
More than 150 years of ecological chaos brought Macdonald here
and if biologists are right, the island's future depends on his
"I think it's going to take a couple of years at the end to
make sure we got them all. The first 90 percent goes really
quickly," Macdonald says.
In 1853, the first ranch pigs broke into the wild and, within a
few years, their population swelled to hundreds. Voracious
scavengers, the pigs dug into hillsides as they foraged for bulbs
and grubs, and snuffed for acorns under majestic oaks, tearing up
That triggered erosion, destroyed Chumash Indian archaeological
sites that are at least 8,000 years old and encouraged the growth
of nonnative plants that choked out scrubby oaks and grasses.
Fennel, an invasive species, now grows so prolifically that on a
hot day the air carries the plant's licorice scent.
The National Park Service has in the past eradicated nonnative
sheep, rats, rabbits and mules on other of the Channel Islands.
In the early 1990s, the fox began to disappear from Santa Cruz
Island at an alarming rate.
Biologists concluded that golden eagles, attracted by the easy
prey of piglets, had colonized the island and also were feasting
on fox. For years, the dominant and fish-eating bald eagles had
kept the golden eagles away, but they were wiped out by DDT dumped
off the coast beginning in 1947.
The fox population plummeted more than 90 percent, from more
than 1,000 to fewer than 100 animals today. Last year, the federal
government listed the fox as an endangered species.
The public park service and the private Nature Conservancy
believe that only aggressive human intervention will save the fox.
Eradicating the pigs, their logic goes, will force golden eagles
to search elsewhere for food, letting the fragile fox population
rebound. To help that process along, biologists have relocated 29
golden eagles to the Sierra Nevada and also introduced 34 bald
eagle chicks and bred 34 fox pups on the island.
Russell Galipeau, superintendent of the Channel Islands National
Park, acknowledges that killing one species to save another puts
his agency in an awkward position. The pig eradication, he says,
fits his agency's mission of restoring the island to its natural
state while saving native species and protecting archaeological
Federal and state law prohibits relocating the pigs, which may
have pseudorabies and cholera, to the mainland. For the same
reason, the carcasses of the dead pigs will be left on the island
to rot. Sterilization and contraception aren't practical because
the plan would fail if biologists miss only a few pigs the
fast-breeding pigs can rebound from a 70 percent population
reduction in just one year, according to Galipeau.
"I'm trying to protect the natural system not what humans
handed us, but what nature handed us," he says. "Sometimes you
have to do the same amount of disruption that damaged a place in
order to restore it."
Critics have argued that, after so long on the island, the pigs
belong as much as the foxes.
One group, the Channel Islands Animal Protection Association,
was formed in the mid-1990s after the National Park Service
poisoned nonnative rats that were damaging vegetation on nearby on
In the current case, the association believes the golden eagles
were attracted not by pigs but by the rotting carcasses of feral
sheep from an earlier eradication program in the 1980s. They
believe the golden eagles discovered the 4-pound foxes not the
pigs and stayed.
"Not only was this story made up, but the pigs are now an
established member of the ecosystem," says association spokeswoman
Scarlet Newton. "The public is being totally deceived."
Vermeer says those claims are unfounded. "We have an immediate
need on Santa Cruz Island," she says. "It's a small price to pay
for preserving an island's unique ecosystem."
