In an epic HeliHack, volunteers braved steep slopes and challenging terrain to remove a record-breaking number of invasive trees in Boosmansbos.
South Africa (02 June 2025) – There’s something magical about Boosmansbos. A wild, tangled wilderness nestled in the Langeberg mountains, it feels ancient, untouched, unbothered, and deeply wise. But even the most remote corners of our world aren’t immune to human impact. Invasive pines, though beautiful in their own right, have been quietly threatening this World Heritage Site, choking water supplies, crowding out native life, and turning delicate ecosystems into fire tinderboxes.
That’s where the HeliHack heroes come in.
In early May 2025, a bold team of volunteers, conservationists and helicopter crews took to the skies and the steepest slopes for a record-breaking mission unlike anything before. Over just three days, they cleared more than 15,000 invasive pine trees from the rugged cliffs above the Duivenhoks River. That’s 1,080 hectares of precious land given back to the wilderness and water security strengthened for over 15,000 people in Heidelberg, Witsand, Slangrivier, and the surrounding farms.
Boosmansbos, managed by CapeNature, plays a vital role in keeping streams flowing, fires at bay, and biodiversity thriving. But it’s no easy feat when your enemy has roots as deep as decades-old pine trees clinging to cliff faces. That’s why HeliHack matters. With 12.8 helicopter hours flown, 21 volunteers on the ground, and precision only a mountain goat (or a chopper) could manage, this was no ordinary clearing operation. It was a dance between nature, human ingenuity, and love for the land.
And the rewards? They go far beyond the numbers. With each pine removed, the resilience of this ecosystem grows. The rivers breathe a little easier. The indigenous fynbos stretches toward the sun. And somewhere in the undergrowth, a miracle happened: the elusive Boosmansbos long-tailed forest shrew, missing for 46 years, was rediscovered. Proof, once again, that when we protect wild spaces, the wild finds a way to thank us.
“We’re securing water, protecting biodiversity, and building resilience for the future.” – Dr Ashley Naidoo, CapeNature CEO
This HeliHack wasn’t just a win for the wilderness, it was a love letter to collaboration. Because saving nature isn’t a solo sport. It’s teamwork between government, scientists, hikers, helicopter pilots, and everyday heroes who care enough to act.
As Provincial Minister Anton Bredell put it, “These operations solve today’s issues and help prepare the Province for the future.” A future where nature isn’t an afterthought — it’s the foundation.
So next time you sip a glass of water, breathe in the fynbos-scented breeze, or hike through Boosmansbos, remember: there are people, taking to the skies and deep in the forest, fighting to keep it all alive. And they’re doing a beautiful job!
