MNV has carried out many surveys of peat deposits in the UK and has used the results from these surveys to restore and improve the quality of the peat.
We carry out peat depth and condition surveys based on systematic grid patterns over the area and using peat corers and probes. The survey results are used to develop peat depth maps which are analysed with maps of slope, altitude, NVC and superficial deposits.
Using the results of the surveys we can identify areas of blanket bog and the hydrological controls which have formed the peat. We can quantify volumes of peat to be abstracted during the construction of a pipeline and recommend ways of restoring the peatland after construction.
The benefits of restored peat lands are their ability to store vast amounts of carbon, to create unique habitats for species such as ground nesting birds and also to attenuate runoff in headwater catchments an reduce downstream flooding.
MNV has carried out work to restore peatlands including the blocking of ditches with peat, timber and plastic pile dams. In addition we have re-profiled peat hags and protected exposed areas of peat with geotextiles.
Many peat deposits have been impacted in the past by commercial forestry. We have carried out work following the felling of the trees to flip the tree stumps, use the tree brash to block ditches, mulched the tree debris and ground tree stumps to ground level.
