Scientists: Fertilizers killing salt marshes

(Continued)

“If every individual could make the decision not to add nitrogen to their lawn, that would help the coastal areas a great deal,” Deegan said.

The next step for Deegan and her team will be to see if they can reverse the damage done to the Sweeney Creek marsh system.

The scientists will stop adding more nutrients and will then observe how long it takes for the marsh system to recover.

“After we stop adding the nitrogen, how long does it take the system to rebound to its natural state?” Deegan said. “This information will be important in reclaiming the health of salt marshes that are currently suffering from nutrient enrichment.”
