The 'Bogfather' nickname has been bestowed upon Dr Peter Jones, a Welsh scientist dedicated to peatland restoration for over three decades. His tireless work is now at the forefront of tackling climate change in Wales, offering a multifaceted solution that combats flooding, prevents wildfires and reverses biodiversity loss.
Peatlands cover just 4% of Wales's surface but store an astonishing 30% of its land-based carbon. Sadly, around 90% of these vital ecosystems are degraded, releasing greenhouse gases into the atmosphere rather than locking them in. Dr Jones highlights that healthy peatland plays a crucial role in slowing water flow, preventing flooding and acting as natural firebreaks – both phenomena set to worsen with a warming climate.
Dr Jones's fascination with these unique environments began at eight years old during a visit to Cors Caron national nature reserve. His passion for 'some of the UK's last truly natural and endlessly interesting' places remains undimmed in his 60s. He explains that peat soil forms from partially decomposed plant remains, trapping materials like pollen, dust and even volcanic ash as it slowly grows.
Historically, peatlands were undervalued, leading to widespread drainage for agriculture and tree planting. They also played a vital cultural role in past centuries, providing fuel for rural communities. Damaged peatlands are highly susceptible to erosion, forming 'peat cliffs' where the surrounding peat has worn away under wind and rain. Dr Jones notes that healthy peatlands are identifiable by specific plants like sphagnum moss, which can hold 20 times its own weight in water.
Working with farmers and landowners, Dr Jones and his team implement restoration techniques such as blocking drains and ditches and re-establishing bog vegetation. These efforts aim to bring back the 'whole range of animals' that rely on healthy peatland, including many scarce or threatened invertebrates. If managed correctly, peat can accumulate at a rate of one millimetre per year, slowly rebuilding these invaluable carbon sinks. Among the diverse species found in restored habitats, Dr Jones cites the fly orchid, which has a unique pollination strategy involving mimicry of female digger wasps.
