Mangrove Ecosystem

REM Mangroves dissipate wave energy and trap sediments

In mature mangroves, it is difficult to locate any remnant of the REM Encasement Device due to shoreline accretion and overgrowth by the tree. The top portion of the encasement in this photo, at the time of planting, measured approximately 1 meter in length above the planting elevation; however, now only a few inches of the encasement that extends above the resulting shoreline accretion can be seen.

Note the size of the mangrove aerial roots which are able to dissipate wave energy and continue to trap sediments. The shoreline has been stabilized and is now protected by the mangroves, removing the need to harden the shoreline with bulkhead or riprap. Mature trees, such as this one, also provide nursery grounds for invertebrates and fish, and critical habitat for a birds and terrestrial animals.

These mangroves reforested with Riley Encased Methodology have continujed to stabilize the shoreline during many Trropical Storms and Hurricanes, which included Hurricanes Jeanne, Frances and Wilma (category 2 and 3 storms) and will continue to provide shoreline protection during future storms.
