Scotland’s Whitelee wind farm cleared 900 hectares of commercial forest, beginning a 2,547-hectare moorland restoration for black grouse and wading birds
Above the plateau south of Glasgow, 215 wind turbines rotate continuously over an area that is slowly transforming into something new. Below them, where rows of commercial conifers once choked the land, bog cotton is sprouting, sundews are spreading over the peat, and wading birds are flying in to reclaim the land that had been drained and planted for decades.
This is Whitelee — the UK’s largest onshore wind farm — and over the past 15 years, a handful of ecologists and contractors have been laboring year by year to restore its moorland.
A forest falls, a moorland rises
Until the arrival of the wind turbines, Whitelee would have hardly looked anything like it does now. Commercial plantations of dense coniferous trees, typical of the uplands of Scotland in the mid-twentieth century, stood upon the plateau; they concealed below the bog which is several thousand years old. Such timber plantations were effective, but in terms of ecology, they had been virtually mute for many years because of drainage ditches dug into the bog.
Earlier recognition of their innovation had come in the form of RSPB Scotland’s nomination for a Sustainable Development Award in the 2016 Nature of Scotland Awards.
As the wind farm was constructed by ScottishPower Renewables, about 2,224 acres of the commercial forest was cleared for it. Tree clearance for wind turbines is not usually considered as an environmental victory. However, at Whitelee, it created an opening.
The contrast between the two is quite real. The conifer monoculture was doing nothing; it provided low light, acid needles, and compacted soil, but once the trees were removed, the peatland beneath it got a chance to breathe again.
The juxtaposition between the two is very real. The conifer monoculture provided low light, acidic needles, and compacted soil, but after those trees were cut down, the peatland underneath had the opportunity to breathe once more. Bog plant life reclaimed the bog, and birds made use of the open area where they hadn’t seen it in decades. This clearing marked the beginning of a 6,294-acre moorland restoration project, the most ambitious one undertaken in the UK by any wind farm.
The ecologists who spent 15 years rewetting a bog
Restoring nature to this scale is certainly not a one-off job. Everyone has to return each year to understand what the area needs and do their best to meet it.
Glenn Norris is an ecologist from ScottishPower Renewables. Glenn is a very important person in all of this. For the past 15 years, Glenn has been working with Strath Caulaidh Ltd to survey the land, try out various techniques, remove those that did not work, and refine the ones that did. It takes a lot of time to rehabilitate a peatland, and it’s supposed to.
Two methods arose from this trial-and-error approach. The first technique of ground smoothing deals with the undulations created by tree felling operations; leveling these ridges and furrows ensures reduced drainage capacity to allow wetland conditions to be recreated. The second method is wave damming, which uses diggers to press the peat on both sides of drainage ditches. These methods have arisen from observations made on the response of the landscape of Whitelee. As put forth by Norris: “We are not just addressing carbon emissions at Whitelee through our renewable energy technology but are also exploiting the carbon store of the peatland itself: there are dual advantages.”
What the restored acres mean on the ground
Numbers don’t lie. 2,752 acres of peat bog land out of the 6,294 acres required for restoration are already back on track—equivalent to the size of a Falkirk town.
Go there today and you will see the wild cranberries growing across the ground, carnivorous plants trapping insects in wet areas, and wading birds operating on the marshy edges of the newly rewetted pools. Black grouses—which have withdrawn from the degraded peat bogs—have made their way back into the area. The vegetation composition that indicates a healthy bog is being rebuilt, even if it is doing so at a slow pace.
However, in essence, something else has been going on, something unseen yet equally important. A peat bog in good condition serves as a carbon sink, and, at the Whitelee bog restoration site, the bog could even capture carbon equal to 3.6 million metric tons of CO2. The contrary happens in degraded peat bogs, which emit instead of store greenhouse gases, making up 15% of Scotland’s total greenhouse emissions.
Above all, 215 wind turbines produce enough power for 350,000 homes. At the same time, the entire site can be visited by anyone, as it is open to the public, being the habitat of walkers and bird watchers, among others.
Methods invented in Whitelee are now industry standards in Scotland
Methods such as ground leveling and wave blocking did not just remain restricted to Whitelee. They have already been formalized by NatureScot in its technical compendium on peatland restoration.
Earlier recognition of their innovation had come in the form of RSPB Scotland’s nomination for a Sustainable Development Award in the 2016 Nature of Scotland Awards. It had recognized the methods not just as an expensive but as an innovative effort.
Agriculture Minister in the Scottish Government Jim Fairlie put it very clearly: “Rehabilitating degraded peatland is probably the cheapest method of reducing carbon emissions and helping combat climate change. There are many benefits, such as reduced flood risk, water quality improvements, and biodiversity.” Even the impact of the project has stretched beyond Scotland, as other renewable energy companies in the UK have started to use this method on their wind farms, inspired by Whitelee Wind Farm.
What Whitelee proves about wind energy and wild land
The easy assumption is that industrial infrastructure and ecological restoration pull in opposite directions. Whitelee complicates that assumption in useful ways.
Cutting down trees for turbines was always bound to have little to do with conservation. However, seeing the cleared land as an opportunity, rather than a result, has been enough to transform the land into something else. The wind farm was not merely coexisting with restoration; it was making it possible.
The final image of the restored landscape—with increased populations of black grouse and wading birds, vegetation forming across the plateau—is partially a vision. The direction, however, is set.
What Whitelee ultimately asks you to consider is whether trade-offs we assume are fixed might sometimes be negotiable. A wind farm is now a wildlife sanctuary. An ecologist’s 15-year patience is now an industry standard. The bog that was drained and planted over is, slowly becoming itself again. That’s worth sitting with.
