Description:
An Estuarine intertidal irregularly flooded emergent marsh on the southern tip of Jean Lafitte National Park and Preserve.
|
Conditions: This picture was taken at 1:59 pm on June 11, 2002. Nice sunny day with unlimited visibility. Marsh is not flooded by the tide. This area is unique because of salt water influence from the south and fresh water push from the north due to a Mississippi River freshwater diversion project (Davis Pond).

Disturbances: The southern tip of Jean Lafitte NHPP is constantly eroding. The marsh (facing SW) has been eroded due to normal erosion and also hurricane activity. |
Comments: The picture shows a marsh with fresh and salt influences. The area continues to erode to the north. The area is accessible by commercial air boat guides. |
