The shallow peatlands of Exmoor have been modified by human intervention since their inception over 5000 years ago. Agricultural drainage, peat cutting and burning have altered the hydrology causing erosion, vegetation change and loss of ecosystem services. As part of the Exmoor Mires Partnership, restoration aiming to reinstate the typical high water tables of these mires has been undertaken since 1998.


Existing monitoring in Exmoor indicates that restoration methods have not yet achieved the desired return to active blanket mires and the dominance of Molinia caerulea persists after hydrological restoration. In order to address this, the Exmoor Mires Partnership intends to trial the reintroduction of Sphagnum, as a complementary process to aid habitat restoration. The proposed PhD project aims to investigate which is the most effective approach to Sphagnum reintroduction and to determine whether restoration of vegetation diversity will have a long-term impact on the carbon budget.


The PhD will text the following:

Hypothesis 1. Sphagnum re-growth can be accelerated through reintroduction techniques.

Hypothesis 2. Sphagnum reintroduction changes the dominant plant type from vascular plants to mosses and in turn, this increases plant diversity at the site.

Hypothesis 3. Methane emissions and DOC release decrease during the reintroduction process decrease as the dominant plant type changes from vascular plants to Sphagnum and other mosses.

Hypothesis 4: Overall, Sphagnum reintroduction shifts the carbon balance of the site to become closer to that in mires in natural condition.


The project will have a strong practical element working with restoration contractors to trial new techniques and will contribute to the practical knowledge on vegetation restoration processes and techniques. The project outcomes will inform the design and management of restoration projects across the UK and provide evidence supporting the emerging market of paid ecosystem services, whereby landowners may be remunerated for restoring their peat resource.
