It’s an odd thing to do, deciding to call a tree ‘Cathleen’ and then pinning a name tag to its trunk. But we live in odd times, so out of joint with our surroundings that sometimes it takes strange tactics to get our attention.
‘Cathleen’ is a magnificent elm tree in my home city of Sheffield. Like all trees, Cathleen is a bearer of stories, not just her own but also those of the myriad tiny creatures who depend on her for life, and of the much larger human creatures living in the quiet suburb where Cathleen has stood for at least 150 years.
Now, however, humans may be about to bring Cathleen’s story to a sudden end, felling her along with thousands of others in what has been called Sheffield’s ‘chainsaw massacre’, part of a massive, city-wide scheme to upgrade the city’s roads and pavements.
There’s no denying that many of the improvements to our streets are both welcome and overdue, but it’s only now that some of us are waking up to the fact that the work is scheduled to involve destroying up to 18,000 trees, many of which are completely healthy. More than 3,500 have already gone.
It’s horribly appropriate that elm trees like Cathleen are traditionally associated with death and the underworld. Elms were often planted in churchyards and their strong, durable wood has been a popular choice for coffins.
There’s also a darker and more recent link between elm trees and death: Dutch elm disease, which since the 1960s has destroyed more than 25 million elms in the UK alone.
Roger Deakin, in his glorious paean to trees, Wildwood, describes Suffolk in the 1970s as ‘a landscape of many elms … cumulus clouds of their canopies on every horizon, elms in the hedges and at the corners of fields, pollard elms like milestones in the green lanes’. But now only a few hundred remain in the entire country and any that live for more than about twenty years are likely to succumb to the disease.
So ‘Cathleen’, reckoned to be between 150 and 200 years old, is a rare tree indeed. It’s still unclear why she and a few dozen more survived the outbreak when others didn’t and it’s possible that her DNA may help scientists develop disease-resistant elms in the future.
You would think, wouldn’t you, that such an extraordinary specimen would be a source of pride anywhere, and particularly in a place that is renowned for having more trees per inhabitant than any other in Europe and was recently rebranded as ‘the outdoor city’.
Yet, unbelievably, Cathleen is at risk of being felled as part of the ‘Streets Ahead’ project run jointly by Sheffield City Council and Amey plc, a company described on Wikipedia as an ‘infrastructure support provider’.
I won’t rehearse here the reasons why felling healthy trees is incredibly stupid, or highlight the appalling lack of transparency there is over the plans, or the council’s inexcusable failure to get the trees assessed by independent arboriculturists. It’s all powerfully summed up by Professor Ian Rotherham on his blog here.
I want to focus on two things that strike me as especially sad about this debacle. The first is that it underscores the extent to which we as humans have become divorced from the natural world, what has rightly been called ‘our common home’.
We are so numbed by our culture of mass production and easy consumption, for example, that Amey has been willing to gamble that it can quash protest by promising to plant a new tree for every one they cut down.
It’s as if trees were washing machines or car tyres, easily replaced and with only minor variations between different models.
They are not. Under the plans, a magnificent mature lime, for example, could be replaced by a different species just seven years old. It’s like knocking down someone’s family home and promising them a new-build in a different area – they both have four walls and a roof so what’s the problem?
As Cathleen’s story demonstrates, even trees of the same species have their own, distinctive stories. This, presumably, is why campaigners are choosing to name threatened trees – as a winsome and clearly necessary way of drawing attention to their individuality.
Each tree also represents a unique habitat. Cathleen, for example, is home to a colony of rare White-letter hairstreak butterflies which almost became extinct when Dutch elm disease destroyed most of their preferred food sources.
The story of Cathleen demonstrates how ecologically illiterate most of us are, how blind to the wonders that surround us in the nonhuman world. It beggars belief that we can even contemplate destroying a tree of this stature, rather than doing all we can to protect it.
The second thing, which makes me more angry than sad, is that this is not a ‘Sheffield’ kind of thing to do. My adopted city is a wonderful place with a long and proud history of radical thought, full of poets and artists, and cyclists and runners, with two brilliant universities, and acres and acres of green space, much of it donated to us by our philanthropic forbears. Thoughtless, selfish, stupid actions like unnecessarily destroying trees do not belong here.
A number of local groups in Sheffield are campaigning hard to change the Streets Ahead policy on tree felling.

Even if you don’t live in Sheffield, you could sign the petitions and add your voice: trees are a national treasure, not just a local one.
