Snake in the Grass: An Everglades Invasion
19.05.12
There are places in the Everglades where the landscape seems alive, rippling with movement, raucous with sound. Reptiles, amphibians, mammals and birds fill the grasses, trees, sloughs, and sky above. The vast majority -- egrets and cranes, frogs and toads, alligators and crocodiles and hundreds of other species -- are native, natural components of the ecosystems.
But there are more than a few that are invaders, non-natives that arrived in one mode or another. Though the majority of these are relatively innocent, with little direct impact on the surrounding environment or their newfound neighbors, one in particular is having an impact far more extensive than a rippling in the grass.
As a report out this week testifies, the constricting python is a potent predator, a quick-growing mass of muscle that is a threat to anything that moves in the Everglades. Its reach is far and its appetite large, with scientists telling us that populations of small mammals -- raccoons, opossums, even bobcats -- are being wiped out of some parts of the national park by these slithering predators. But its prey also can be much, much larger.
