The answer is: " invasive " . _______________________________________________________ "<span>The boa constrictor in the Everglades is an example of an <u> invasive </u><u /> species that is impacting local species." _______________________________________________________</span>
Since the mid-1990s, several species of non-native, giant constrictor snakes, such as Burmese pythons and boa constrictors, have surfaced in localities throughout southern Florida. Several are known or suspected to be breeding and appear to be spreading northward. Increasingly, media and other reports of sightings or encounters with these animals have emphasized the dangers they could impose on native species, ecosystems, pets, and people. The USGS Fort Collins Science Center (FORT), government resource management agencies, the University of Florida, Davidson College (NC), and The Nature Conservancy have been collaborating on research and intervention methods to cope with an urgent need to understand and control these large, widespread predators.
