Snakes threaten Hawaii’s fragile island ecosystem

HONOLULU — Hawaii has been largely successful in preventing snakes from
entering the island paradise over the years and avoiding the grave danger they
present to tropical birds, colorful plants, and the vibrant environment that
draws millions of tourists to the state each year.
But the recent capture of escaped pet snakes — illegal in Hawaii — and the
infestation of the U.S. island of Guam by brown tree snakes, which could easily
make it here via cargo ship, have alarmed wildlife and agriculture officials.
Without any natural predators, authorities say it wouldn’t take much for
snakes to take root and multiply, potentially killing off endangered birds and
flowers that make the islands special. Hawaii, home to more endangered species
per square kilometer than anywhere else in the world, could potentially face the
same fate as Guam, where brown tree snakes overran the island following World
War II and wiped most birds from the skies.
"It has a high potential to be devastating to Hawaii," said Earl Campbell,
assistant field supervisor for the Pacific Islands Fish and Wildlife Office
within the U.S. Fish and Wildlife Service. "I would look at Guam as the template
for what could happen in a range of tropical Pacific Islands that have no
snakes."
Hawaii is so serious about keeping snakes out that the fine for possessing an
illegal animal can reach $200,000 and up to three years in prison. But snake
owners are granted amnesty if they willingly turn their pets over.
Residents who unlawfully keep snakes as pets create a giant risk when the
reptiles escape or are released into the wild. A nine-foot boa constrictor and
seven-foot albino Burmese python were captured last month.
"No pet snake is welcome because all it’s going to take is the next
earthquake, tsunami, or hurricane to blow open all those enclosures and
introduce to the islands all those pets that were being kept in a house," said
Fern Duvall, a wildlife biologist for the state Division of Forestry and
Wildlife on Maui. "It’s really a grievous problem."
Besides the pet snake threat, environmentalists also fear snakes could find
their way to Hawaii by hitchhiking on cargo ships, undetected by short-staffed
agriculture inspectors.
If snakes nested and reproduced, it would quickly be too late to stop them
and the Hawaiian islands would be changed forever, said Christy Martin,
spokeswoman for the state’s Coordinating Group on Alien Pest Species.
"It’s our moral responsibility to try to keep them out for as long as
possible. I don’t look forward to future generations saying, ‘They really
dropped the ball on that one. There used to be birds in Hawaii,"’ Martin said.
The number of snake sightings fluctuates from year to year, but they’ve been
steadily rising, said Carol Okada, manager for the Hawaii Department of
Agriculture’s Plant Quarantine Branch.
There was a yearly average of nearly 24 snake sightings reported statewide
between 1990 and 2000, according to a 2001 study titled "Risk to Hawaii from
Snakes" published in Pacific Science. Okada said there were 36 snake
reports in 2008, with data from other recent years not immediately available.
"We don’t want the trend to continue," Okada said. "In Hawaii, with all its
lush vegetation, you don’t want to be worried about snakes while you’re hiking."
A snake invasion would have far-reaching effects on the islands, permanently
changing its landscape, Duvall said.
First they’d eat bird eggs and small birds, including 34 species of
endangered forest birds found in Hawaii such as the Maui parrotbill, crested
honeycreeper, and Hawaiian crow, he said. Spiderwebs would drape trees and
darken forests without birds to kill them. Insect populations would boom. Power
outages would increase as snakes hung from electricity lines.
These consequences have already occurred on Guam, according to Campbell, who
said the snakes there established themselves across the landscape in about three
decades.
In the July captures on Oahu, the snakes appeared to be pets, agriculture
officials said. The docile boa constrictor was found by pig hunters on a dirt
road and the python was retrieved from a home after police received a tip.
The black market pet trade is largely responsible for snakes finding their
way to the islands, Martin said.
Snake enthusiasts find dealers through the internet and ship baby snakes by
mail to Hawaii in small boxes, she said. Legitimate pet stores won’t send snakes
to Hawaii, she said.
With only 50 agriculture inspectors statewide, down from 95 in 2009 because
of budget cuts and layoffs, the state has a hard time catching snakes when
they’re mailed in, she said. Efforts to prevent snakes from escaping Guam have
been more successful, and only one brown tree snake has been found in Hawaii
since an inspection program started on Guam in 1994, Campbell said.
Organizations including the Hawaiian Humane Society help rid the islands of
pet snakes by picking them up from homes with no questions asked, said
spokeswoman Jacque LeBlanc.
"In the case of the boa that was found, that boa was big enough to eat a cat
or harm a child," LeBlanc said. "They’re dangerous to people and other animals."
