Environmental Factors

 
Image of bayou with surface covered by thickly growing vegetation

Bayou Coquille was once a distributary of the Mississippi River. It's now a sleepy little bayou, often covered with aquatic plants. Will environmental factors like flood control and climate change turn it into a swamp, a marsh, or a coastline?

Any environment is a living thing that changes daily with the weather, the birth or death of plants and animals, and a thousand other factors. South Louisiana is no exception: rising sea levels, subsiding (sinking) land, human interactions, and new species all have an effect on the land and its inhabitants.

Alligators have two eyelids! The second inner eyelid is clear and used like goggles while the alligator is under water. These amazing reptiles have been around since before the dinosaurs, and they are designed for life in the water.
