New Study: Wetlands Work Wonders in Just 12 Months

Restoring floodplain wetlands can cut carbon emissions by 39% in just one year while boosting water retention and ecosystem health—without the spike in methane often seen in peatland recovery, according to new research.

The study, led by RMIT University and published in the Journal of Environmental Management, tracked wetland sites along the Loddon River in Victoria, Australia.

Restored areas saw a 55% rise in soil moisture, a 12% increase in surface carbon stocks, and significantly better nitrogen retention, improving water quality and flood resilience.

Native plant cover surged, and slower leaf litter breakdown from native species indicated stronger carbon storage in the soil.

A separate site, restored six years earlier, showed a 53% jump in organic carbon, confirming long-term gains.

Lead author Dr Lukas Schuster said the results show wetlands could be a “secret weapon” against climate change.

The research, supported by the Australian Government’s Future Drought Fund and other partners, highlights how riparian wetland restoration can deliver rapid, lasting climate and biodiversity benefits.
