Dumped at the park and elsewhere by pet owners who wanted to get rid of them, the snakes — which can grow to 20 feet and more than 250 pounds — dine on wading birds, small mammals and anything else they can squeeze to death.
Their numbers have risen steadily, with more than 300 removed from the park in 2008, up from about 250 the previous year, said Skip Snow, a biologist in charge of handling the python threat.
Marshall Meyers, chief executive officer of the Pet Industry Joint Advisory Council, said the pet industry wants to help solve the problem but opposes Nelson's bill because of its scope. Although aimed at the Burmese python, it would restrict the trade in all pythons, including the smaller, highly popular ball python, which has not been found abandoned in large numbers.
Breeders and dealers are "extremely worried," he said.
"It could have a significant impact on people in the reptile community," he said. In Florida alone, the trade in pythons generates about $10 million a year, he said.
Although trade restrictions would come too late for the Everglades, with its entrenched python population, they could prevent the problem from recurring elsewhere. Most of the southern third of the United States — from Virginia through central
