Flanders Moss in Scotland has seen the return of key bog plants such as sphagnum (peat moss) and cottongrass — so important now that we know bogs can store the carbon we don’t want in the atmosphere.
My father-in-law sold peat moss, among other agricultural products, for his entire career. He usually got the peat from Canada, although other people source it from places like Germany and Ireland. In Moat, Ireland, our friend James Hackett relied on peat for warming the house. (Burning it was not the best thing for his health.)
Today’s story is about Scotland’s heightened focus on protecting peat bogs so they can store carbon and fight global warming.
Phoebe Weston reports at the Guardian, “Flanders Moss bog is slumped on the flat, farmed landscape of the Carse of Stirling in Scotland like a jelly fungi. It wobbles when you walk on it, and a metal pole goes down eight metres before reaching hard ground. This lowland-raised bog is a dome of peat fed mainly by rainfall and it acts like a single organism – the whole thing has to be looked after for any part to be in really good shape. If it is drained in one area it will affect the water level across the entire bog.
“For much of human history peat bogs have been thought of as wastelands. This 860-hectare [~2,200 acres] site has been hacked away and drained since the early 1800s to make space for fertile farmland below. …
“It is now recognized that peat bogs are among the greatest stores of carbon and, after decades of restoration, the holes in the peat at Flanders Moss have been patched up. Areas that used to be purple with heather are turning green as key bog plants such as sphagnum (peat moss) and cottongrass come back. The bog rises out of the land like a sponge and ‘breathes’ as changes in the weather and water level cause it to swell and contract.
“Researchers in Scotland are tracking ‘bog breathing’ using the latest satellite technology that can detect just a few millimetres of change. … Thanks to the restoration work, the water table has risen [and] is now at the surface. As the bog draws in water from the surrounding land, it helps manage flood risk. Flanders Moss bog has removed [about 2,200 acres] from the Forth catchment, reducing flooding downstream. …
“The Scottish government-funded Peatland Action project, which started in 2012, is helping revive 25,000 hectares [~61,776 acres] of degraded peatland. In 2020, the Scottish government committed [about $300 million] over 10 years to bog restoration in a bid to lock carbon in the land. …
“It takes about a month to process the satellite data for a third of Scotland, which is available through the Copernicus Open Access Hub. The technology is still in development but is likely to be cheaper than ground-based mapping. …
“Despite these restoration efforts, Flanders Moss is still a net emitter of carbon. … Stopping these emissions and preventing further degradation are the primary objectives of the restoration project.
“Bogs work on a different timeframe than humans. They form slowly … taking up to 1,000 years to grow one metre. But [David Pickett, who manages the site with his National Nature Reserve] team has jump-started recovery. ‘We’ve done most of the big work here,’ he says. ‘Now, it’s a question of waiting. The process of fixing this site will last 100 years, and the benefits of work being done now will only be seen by the next generation.’
“It’s easy to see why bogs weren’t popular. They are stores of partly decayed organic matter, which are too acidic and devoid of nutrients to support healthy trees. But this bog is colorful and has a fresh, earthy smell. As well as being a fantastic store of carbon, this ancient, watery land – healthy peat is about 90% water – is also rich in wildlife, including rare lizards, dragonflies and even snakes.
“ ‘There isn’t headline sexy stuff like puffins and seals but you go around the boardwalk and it’s a fantastic place,’ says Pickett. ‘I always used to think bogs must have been named on a Friday after a really bad week. We’re trying to change the perception of bogs but it’s a hard sell.’ ”
