Green plant growing underwater. Caption: Hydrilla is an invasive species on a path of destruction.

The hydrilla, a non-native invasive plant species, is overtaking Florida's Wakulla Springs, threatening many species that call the waterway home. The hydrilla has such a stranglehold on the springs that its aggressive growth cycle has made it impossible to totally eradicate. Instead efforts are being made to control the plant's growth in an effort to stop its encroachment into Florida's northern panhandle. Segment of video from Wild Chronicles Series.
