In the summer of 2018, CBA worked with Eglin Air Force Base, Corvias, and over 100 volunteers to create a reef breakwater and living shoreline to reduce erosion along Post’l Point. Nearly a year later, native marsh grasses and other vegetation are beginning to stabilize the land behind the breakwaters.
The photo below was taken in January 2019, during a very low winter tide. During higher tides, the limestone rocks reduce the wave energy hitting the shoreline, changing the aquatic environment marsh grasses can use to grow.
The second photo was taken just last week. As you can see, the native smooth cordgrass (Spartina alterniflora) has not only been able to take root, but is now growing above the waterline. In addition to providing critical habitat, the grass roots will stabilize sediment, which further reduces erosion and can actually build out the shoreline itself.
