Raising water tables by blocking drainage channels (or grips, or groughs) helps to keep the peat wet and reduces erosion by wind & water. To safeguard the peat long-term, it needs to have vegetation cover and restoring the sphagnum mosses that formed the peat in the first place is a good way to go. Techniques to reintroduce sphagnum mosses are developing. If these mosses are kept wet after establishment, they will start to form more peat, and capture, then store carbon from the atmosphere.
It is a good thing to be doing especially if in the future, the value of the restoration work is recognised and creates a source of income to offset the costs of the restoration work.
