Article Synopsis
- Patchy data on litter decomposition in wetlands limits understanding of carbon storage, prompting a global study involving over 180 wetlands across multiple countries and climates.
- The study found that freshwater wetlands and tidal marshes had more organic matter remaining after decay, indicating better potential for carbon preservation in these areas.
- Elevated temperatures positively affect the decomposition of resistant organic matter, with projections suggesting an increase in decay rates by 2050; however, the impact varies by ecosystem type and highlights the need to recognize both local and global factors influencing carbon storage.
Wetland ecosystems are critical to the regulation of the global carbon cycle, and there is a high demand for data to improve carbon sequestration and emission models and predictions. Decomposition of plant litter is an important component of ecosystem carbon cycling, yet a lack of knowledge on decay rates in wetlands is an impediment to predicting carbon preservation. Here, we aim to fill this knowledge gap by quantifying the decomposition of standardised green and rooibos tea litter over one year within freshwater and coastal wetland soils across four climates in Australia.
