This hair-like filamentous alga can form large benthic (on the bottom) and surface mats. In some areas, such as the Rainbow River, it is quickly covering and smothering native submersed plants.
Lyngbya can be transferred from one system to another via any interaction of fauna (e.g. birds, turtles, alligators, raccoons, insects, people, etc.). This can involve cells attached to the surface of the organisms, or via viable cells (or cysts) incorporated into fecal material. Cells or cysts can also be transported by wind events, which can transport droplets of water or particulate material over large distances, and by boat hulls and bilge water.1
