‘It has destroyed years of work’: Cornish beauty spot loses 80% of its trees to Storm Goretti

The tidal island of St Michael’s Mount in the far south-west of Britain is usually a place of peace and quiet.But it has become a hive of noisy activity as gardeners equipped with chainsaws and wood chippers get to grips with the devastating damage caused by Storm Goretti.The latest count shows that 119 large trees were felled, including holm oaks, hollies, sycamores and Monterey pines the size of four-storey homes. About 80% of the island’s tree cover has been lost.“When I got out here the next morning, it was still dark but I could see the tree line had changed,” said the head gardener, Darren Little. “As dawn broke, the scale became clear – it’s devastating. In a few hours it destroyed years of work and changed the profile of the island.”St Michael’s Mount lost sycamores, holm oaks, hollies and Monterey pines to Storm Goretti.

Elms have also done well. “I think they whip with the wind,” said Little.But a holm oak planted to mark the birth of Prince Harry in 1984 has been uprooted. It is not possible to crane such trees back into place and hope they recover because the soil is too shallow – another reason why the island was so badly hit.The island’s trees are rooted in shallow soil, making them vulnerable to extreme winds.

The Cornish name for the island – Karrek Loos yn Koos (grey rock in a wood) – suggests the outcrop was once surrounded by forest.However, the climate crisis is leading to stronger storms, wetter winters and drier summers in the UK. “We’ll have to bear that in mind when we rethink and redevelop,” Little said.Back on the mainland, woods and copses important for wildlife have been damaged. A belt of pines near Penzance known as Bog Plantation has been razed. Birdwatchers flocked to this area last January when a booted eagle, a rare visitor to the UK, dropped in.Henry Mathews of St Aubyn Estates said there was a ‘feeling of great sadness’ on St Michael’s Mount.

It’s impossible to replace that.”Other spots hit include Penlee Park in Penzance, the setting for an art gallery that is home to paintings by members of the Newlyn School , and the Growing Links community garden near Penzance.Despite the devastation, the people of Cornwall vowed they would replant and restore their landscapes.At Tremenheere Sculpture Gardens, which has views across to St Michael’s Mount, magnificent trees including a woodland walk of mature beeches have been lost.But Polly Bolitho, who works at the gardens, said they were looking forward. “Even in this moment of loss, this garden always evolves,” she added. “It’s in the spaces between light and dark that new ideas begin. From storm to story, we look ahead to the next chapter.”
