Abstract

The AA. measured the carbon budget of 8 sites: 4 restored-revegetated sites, 2 unrestored bare soil control sites, and 2 intact vegetated controls over 2 years (2006-2008). They considered the following flux pathways: dissolved organic carbon (DOC); particulate organic carbon (POC); dissolved carbon dioxide (CO2); primary productivity; net ecosystem respiration, and methane (CH4). The study shows that unrestored, bare peat sites can have significant carbon losses. Most sites showed improved carbon budgets (decreased source and/or increased sink of carbon) after restoration; this improvement was mainly in the form of a reduction in the size of the net carbon source, but for one restored site the measured carbon budget after 4 years of restoration was greater than observed for vegetated controls. Therefore, the carbon sequestration benefit of peatland restoration is evaluated
