Constructed wetlands do a good job in their early years of capturing carbon in the environment that contributes to climate change – but that ability does diminish with time as the wetlands mature, a new study suggests.
Constructed wetlands do a good job in their early years of capturing carbon in the environment that contributes to climate change – but that ability does diminish with time as the wetlands mature, a new study suggests.
Researchers examined soil core samples taken from two constructed freshwater wetlands and compared them to data from previous studies of the same wetlands over 29 years to determine how well human-made wetlands sequester — or capture and store — carbon as they age.
Findings showed both wetlands captured similar amounts of carbon over the decades, but neither has shown a net gain or loss since year 15.
