Mars Coral Reef Restoration Efforts Show Progress

Our business and the many communities we source raw materials from depend on the ocean and its reefs—for food, income and protection. Yet—up to 90% of coral reefs are predicted to be lost by 2040, threating 25% of global marine biodiversity with extinction caused by climate change, destructive fishery practices and reduced water quality. 

Since 2011, we’ve been continuously developing and refining a low-cost scalable method of coral reef ecosystem restoration called the Mars Assisted Reef Restoration System. The method is based on installing a continuous web of “Reef Stars”—hexagonal sand coated steel structures with coral fragments attached—covering barren coral rubble fields and gaps between the remaining live coral on the reef.  

Despite the devastation—we are optimistic. 

2020 Mars Assisted Reef Restoration System Progress To Date 

  • Within just two years, coral cover has increased from 10% to 60% at key restoration sites. 
  • There has been tremendous increase in the number of fish—approximately 125,000 more fish per hectare of restored reef.  
  • Many new coral species settle underneath and onto the “reef stars” supporting life both within and beyond the reefs.
