Over the past eighteen months, the Army Corps of Engineers’ Deep Dredge of PortMiami has continuously released dirty water throughout Biscayne Bay and onto our surrounding reefs. The dredging will continue through at least August 2015. Over the course of the Dredge project we have observed levels of suspended silt far beyond what is environmentally acceptable or healthy in a coral reef environment. Silt that is directly causing coral mortality in areas far beyond where the Army Corps predicted.
One of Coral Morphologic’s biggest ongoing concerns during the Deep Dredge has been the well-being of a hybrid fused-staghorn coral (Acropora prolifera) colonizing the Fisher Island side of Government Cut. This coral is what kickstarted our interest in documenting the extent of coral colonization within Miami’s coastal waterways, and was the subject of Colin’s 2011 TEDxMIA talk ‘A Hybrid Future: The Corals of Miami‘. The concerns we expressed to the State of Florida about this coral is ultimately what led them to provide us with permits to rescue corals from the dredging far offshore… but not for the hybrid itself (or any other corals on Fisher Island).
