Short summary
Short summary
Greenhouse gas emissions were measured and compared from natural coastal wetlands and their converted agricultural lands across annual seasonal cycles in tropical Australia. Ponded pastures emitted ~ 200-fold-higher methane than any other tested land use type, suggesting the highest greenhouse gas mitigation potential and financial incentives by the restoration of ponded pastures to natural coastal wetlands.

Short summary
Invasive feral pigs are globally widespread and cause massive damage to wetlands by trampling, grubbing, and digging the soil. We investigated whether these impacts would lead to increased greenhouse gas emissions. Emissions of methane and nitrous oxide, two potent greenhouse gases, were higher in sites disturbed by pigs compared to undisturbed sites. Thus, managing feral pigs could reduce soil greenhouse gas emissions.
