November 14, 2016 (Source: FIU) - When it comes to storing carbon, scientists have put a price tag on the value of mangroves in Everglades National Park and it’s in the billions. Based on a scientific cost estimate, the stored carbon is worth between $2 billion and $3.4 billion, the researchers found. It is a relatively small price when considering the cost to society if the carbon currently stored in these mangroves were ever released into the atmosphere, according to the researchers at FIU who co-authored the study.
"Although the Everglades National Park is a protected national treasure, the National Parks Service doesn’t have much control over freshwater flowing into the park," said Mahadev Bhat, co-author of the study and professor in FIU's Department of Earth and Environment. “If there isn’t enough freshwater flowing through the Everglades, we may eventually lose some of the mangroves. And once you let stored carbon out, that same carbon can lead to increased global warming and cost society a lot more.”
In addition to removing excess carbon dioxide from the air, mangroves provide a variety of other benefits, including flood control, storm protection and maintaining water quality. The billion-dollar price tag reflects the cost to preserve the park’s mangroves and their ability to hold organic carbon intact by restoring freshwater flow to the areas that need it the most.
