Why are wetlands disappearing in Louisiana?

Why are wetlands disappearing in Louisiana?

While Louisiana has 40% of the country’s wetlands, over 90% of the total coastal marsh loss in the continental U.S.’s occurs in the state. Natural causes include hurricanes, saltwater intrusion, subsidence, wave erosion and sea level rise, but human activities are most responsible for accelerated coastal land loss.

What happened to Louisiana’s wetlands?

The State’s wetlands extend as much as 130 kilometers inland and along the coast for about 300 kilometers. Not all the wetlands are receding; in fact some wetlands are stable, and others are growing. But, at the present net rate of wetlands loss, Louisiana will have lost this crucial habitat in about 200 years.

What is being done to protect Louisiana’s wetlands?

Louisiana’s Master Plan aims to rebuild and sustain the coast through a series of restoration projects. One critical component of restoring Louisiana’s coast is creating diversions, which allow the Mississippi River to deposit its sediment in the delta and surrounding marshes as it did for over 7,000 years.

What is being done to stop coastal erosion in Louisiana?

Reconnecting the Mississippi River to its wetlands to help restore southeast Louisiana’s first line of defense against powerful storms and rising sea levels. Planning for a smaller, more sustainable delta, including a gradual shift in population and industry to create more protected and resilient communities.

How does salt water intrusion cause land loss?

Saltwater from oceans can move inland, encroaching on freshwater systems and habitats. This can be a major driver of erosion and coastal habitat destruction. Rising sea levels are also increasing saltwater inundation into groundwater aquifers and estuaries.

Is Louisiana sinking into the ocean?

Louisiana is sinking into the sea — a geological process called ”subsiding” — at a rate of nine millimeters (just over a third of an inch) per year, according to a new report and map published by Geological Society of America. The researchers combined data records from 274 sites across the Louisiana coastline.

Is New Orleans really sinking?

New Orleans, Louisiana is sinking at a rate of 2 inches per year. Both human and environmental factors are to blame for New Orleans’ sinking land. A 2016 NASA study found that certain parts of New Orleans are sinking at a rate of 2 inches per year, putting them on track to be underwater by 2100.

Why is La sinking?

The causes are mostly the thermal expansion of warming ocean water and the addition of fresh water from melting ice sheets and glaciers. But even as the sea takes up more space, the elevation of the land is also changing relative to the sea.
