At my age birthdays are a mixed blessing. On the one hand they’re a cause for celebration (Yes, I’ve made it through another 12 months!). But they’re also a time for reflection on how your body has fared over the last year, which bits of it have started hurting, begun to misfire or even stopped working altogether. Spare a thought, then, for the Old Man of Calke, who’s still hanging on after 1,200 years.

The Old Man is one of many magnificent trees to be found in parkland at the Calke Abbey estate in the south of Derbyshire. Calke Park extends to around 600 acres (240 hectares), and is managed for the nation by the National Trust. Around one third is designated as a National Nature Reserve and Site of Special Scientific Interest.

After the Covid restrictions earlier in the year, our visit to Calke Park in October 2020 provided a welcome opportunity to get close to nature again, strolling past picturesque ponds and along shaded woodland paths. There’s lots to see during a walk around the park, but without doubt the ancient and veteran trees are the stars of the show.

Calke is home to over 650 veteran trees, of which 350 are regarded as ancient trees. What’s the difference? I hear you asking. The Woodland Trust explains that “an ancient tree is one that has passed beyond maturity and is old, or aged, in comparison with other trees of the same species…A veteran tree is a survivor that has developed some of the features found on an ancient tree, not necessarily as a consequence of time, but of its life or environment. Ancient veterans are ancient trees, not all veterans are old enough to be ancient.” Clear as mud? Baffled? Absolutely!

The technical definitions may be more confusing than enlightening, but at an estimated age of around 1,200 years the Old Man of Calke must surely qualify as an ancient veteran. To put it into context, the Old Man was a sapling when the Vikings were rampaging across the country, and already had some 250 years under his belt when King Harold took one in the eye during the Norman invasion of England in 1066.

The Old Man is an English Oak, and although not very tall, it boasts a girth of over 10 metres. The trunk is gnarled, split and holed in places, giving the tree a somewhat battered and time-worn appearance. Despite this it is a massively imposing presence in the Calke parkland and seems to wear its great age lightly.

Thanks to the National Trust’s careful management, the Old Man of Calke will hopefully survive long enough to give several more generations of visitors to the Park the thrill of getting up close and personal with a tree that was in its prime when William the Conqueror first set foot on these shores.
