Giant Rats

GRASSY KEY, Florida (Reuters) - Deep in the heart of the Florida

Keys, wildlife officials are laying bait laced with poison to try to

wipe out a colony of enormous African rats that could threaten crops

and other animals.

 

U.S. federal and state officials are beginning the final phase of a

two-year project to eradicate the Gambian pouched rats, which can

grow to the size of a cat and began reproducing in the remote area

about eight years ago.

 

" This is the only place in the United States where this is

occurring, " said Gary Witmer, a biologist with the U.S.

Department of Agriculture's National Wildlife Research Center in Fort

Collins, Colorado.

 

" They don't belong here and they need to be controlled. "

 

A former exotic pet breeder, living in a small house, bred the

species and allowed the critters to escape.

 

Without eradication, wildlife officials fear the rats could

eventually make their way onto the Florida mainland where they could

quickly destroy fragile ecosystems.

 

" They could cause a lot of damage, " Witmer said.

 

In Zimbabwe, for example, ravenous Gambian rats are blamed for

damaging nut and young pea crops.

 

Grassy Key is a 1,500-acre (607-hectare) spit of land, lined with

subtropical hardwood hammocks and flowering bougainvillea bushes,

about 60 miles north of Key West at Florida's southern tip. Streets

are named after limes, lemons, peaches and avocados.

 

Like other islands in the Florida Keys, Grassy Key is a contrast of

inland rustic wooden cottages just a stone's throw from multimillion-

dollar waterfront mansions.

 

" Florida's become quite the hotbed. Florida and Hawaii are vying for

which state has the most invasive species, " Witmer said.

 

That dubious honor is attributed to the region's encroaching

development, subtropical climate and free-spirited residents who like

to keep exotic species, Witmer said.

 

" VERY MESSY ANIMALS "

 

In mid-April, Florida Keys wildlife officials found another invasive

species: an 8-foot (2.4-metre) Burmese python. The first wild Burmese

snake to be discovered in the archipelago, officials say, was found

in a Key Largo state park.

 

The snake had swallowed two of an estimated 500 remaining and

endangered Key Largo wood rats, one outfitted with a radio-tracking

collar.

 

Unlike the wood rats, the Gambian rats " don't have any real friends,

that we can tell, " said Scott Hardin, the Florida Fish and Wildlife

Conservation Commission's exotic species coordinator.

 

Gambian pouched rats, targeted for eradication during the next six

weeks, are not related to the Key Largo wood rat.

 

The African rats can weigh 6 to 9 pounds (2.7-4 kg), with body shades

ranging from brown to gray. They have large ears, black, beady eyes,

hamster-like pouched facial cheeks, sharp teeth and distinctive long,

stringy and white-marked tails.

 

This week, wildlife officials began baiting 1,000 traps laid out in a

grid with narrow four-inch (10-cm) openings. Peanut butter, almond

extract and anise are the lures.

 

Most of the rats will die quickly in underground burrows after

ingesting the bait laced with toxic zinc phosphide.

 

" They're a big rodent. They're not particularly attractive. I don't

understand why anyone would want them as a pet, " Witmer

said. " They're very messy animals. "

 

The U.S. Centers for Disease Control ( CDC) in Atlanta and

the Food and Drug Administration have banned importation of

Gambian rats since 2003.

 

That was after an outbreak of monkey-pox, similar to but milder to

humans than smallpox, was linked to Gambian rat contact with prairie

dogs in the U.S. Midwest.

 

The CDC hopes to study the carcasses and fecal samples of Gambian

rats from the Grassy Keys to learn about internal parasites, but they

have shown no signs of monkey-pox.

 

" We're lucky that's the case, " Witmer said. " They sure can bite. "
