MMPEAT is a new consultancy and centre of knowledge for peatland research and restoration.

We aim to provide high quality, scientifically proven expertise to the peatland industry and conservation bodies. Whether you're a peatland restorer considering different re-vegetation strategies, a peat extractor weighing up Sphagnum farming, a conservation agency or an ecological consultancy looking for a scientific partner, we would like to work with you.

Over the last 10 years we've worked with a number of peatland restorers and industry bodies to monitor the success of different re-vegetation techniques, the relationship between different Sphagnum species to soil biogeochemistry and the long-term success of restoration.

Our team has a long-standing involvement with moorland and bog restoration and draws together a breadth of knowledge encompassing internationally recognised experts specialising in:

Projects

PEATBOG

The PEATBOG project (Pollution, Precipitation and Temperature Impacts on Peatland Biodiversity and Biogeochemistry) investigated the impact of nitrogen pollution and climate change on the health of peatlands, it was funded by the European Research Association BiodivERsA programme.

Through field and laboratory experiments and a European Survey, PEATBOG aimed to understand how nitrogen pollution and changing climate, individually and combined, affect the biodiversity and ecosystem properties of peatlands. 

Restoration of degraded bogs

The blanket bogs of the southern Pennines are among the most degraded in the UK, where regional industrial pollution along with poor management of grazing and burning has resulted in large areas of eroding bare peat surfaces (> 9 km2).

Initial restoration efforts have focused on stabilising the peat surface, using heather brash, lime, fertiliser and grass seed (‘treated’ surfaces). Cotton grass and other species usually begin to naturally recolonise this improved area, but where this process is slow or species-poor, plug plants are used. The overall restoration procedure has been successful in restoring cover to large areas of bare peat. The project has now moved on to the widespread re-establishment of Sphagnum mosses using Sphagnum beads. We are monitoring the success of this methodology.

Our work has been funded through a number of projects with Moors for the Future and we also work with Natural England on cutover bogs in the North-West of England.

DEFRA/NERC Terrestrial Umbrella

We have investigated the effects of pollution (acid rain, re-active nitrogen compounds and ozone) on semi-natural vegetation.

Research is rooted in work on Welsh moorlands where long running nitrogen experiments since 1989 have highlighted the sensitivity to nitrogen pollution of different plant species and ecological processes (eg. raised nitrogen leaching, base cation depletion, increased winter injury, loss of lichens and bryophytes, Ref 1). Research has been supported by funding from the UK Department of Environment and NERC thematic programmes ‘Environmental Diagnostics’ and ‘Global Atmospheric Nitrogen Enrichment’ (1998-2004) and by Manchester Met.
