A Bird's Eye View of Coastal Erosion

Each day I pass an egret on the way to work that lingers in the watery ditches in my town. It amuses me that this elegant bird seems to give little concern to the cars that are passing within ten feet of it. It doesn’t know that I am heading to NWF’s New Orleans field office that has one focus—to restore its wetlands habitat in the Mississippi River Delta before the wetlands disappear. Recently, I got to see the devastating wetland loss from the egret’s perspective.
The Mississippi River Delta, where the mighty Mississippi River meets the Gulf of Mexico, supports more than 400 species of birds. For millions of birds, the delta’s food-rich habitats are critical stopping places before their grueling nonstop flight across the Gulf. But human activities have disrupted the natural balance of the wetlands in the delta and they are receding at alarming rates—nearly a football field of wetlands disappears every hour.
Last week, we took local officials up in a flight provided by SouthWings.org to get an aerial view of how quickly the Gulf is encroaching inland. It was an eye-opening experience that only pictures can convey:
As far as I could see looking south and westward, the wetlands were breaking up into patchy areas. The pattern of deterioration reminded me of the gauzy Halloween material with all the holes that people were using to decorate their homes.
In some places, all you could see were the raised spoil banks from past canals that are no longer necessary as the wetlands turn to open water.
We also passed over restoration areas that were underway, but from the air it was easy to see that the disappearing wetlands exceed the healthy or restored areas. We need to do more restoration on a larger scale to catch up with the amount of wetlands we are losing. Wildlife are depending upon us to restore this once-beautiful delta.
