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.

Did You Know?

A Water Moccasin swims through the bayou.

The cottonmouth or water moccasin can warn you of its dangerous bite in many ways. It releases a musky odor and opens its mouth wide to show you its white mouth and fangs. Show respect for snakes and all wildlife and always keep a safe distance away.
