A recent report on the "Exotic Invasion" is claiming that despite the deep freeze of 2009, invasive species of all types still plentiful in Florida. However what is interesting to me is despite claims of the animals ability to migrate, officials are finding the animals in the same spots as before.

From the Miami Herald:

“Right now, the numbers aren’t all that different,” said park biologist Skip Snow. “We’re finding them in the same places we’ve been finding them.”

While scientists can only estimate the toll the Big Chill took on the army of exotic reptiles, fish and plants in the wilds of South Florida, field observations over the last year suggest nature knocked them down but not out. Some already are speeding down the road to recovery.

David Hallac, the park’s biological resources chief, said he expected a sharp decline in captured snakes. But last year’s total of 322 fell only about 10 percent from 2009.

One species that appears to have seen a sharp decline, and I will mention in my regular trips to Florida, the only wild invasive I have seen on a regular basis is the Green Iguana.

Once about as common as coconuts, green iguana have grown scarce all the way down to the Keys. At previously infested Bill Baggs Cape Florida State Park on Key Biscayne, the largest lizards — six-footers that might give a pit bull pause — have vanished.
But Elizabeth Golden, the park’s biologist, said she’s seeing small greens pop up. There also are plenty of black spiny tail iguanas in all sizes, another species that seems to have weathered the chill, she said, possibly protected by its underground burrows.

This gives a far different report than what we are getting from herpers.
