Those looking out across the moor in West Yorkshire these days will see clough valleys studded with pale green tree tubes, each housing two-year-old saplings – a whopping 65,000 new trees that have been planted this year.

In 20 years, it is expected these trees will have grown into montane woodlands full of oak, birch, hazel, rowan and holly, creating wildlife-friendly corridors through the cloughs across the moor, boosting biodiversity and helping to mitigate the effects of climate change.

They represent the first stage in Landscapes for Water, a joint project for the National Trust and Yorkshire Water – the region’s two biggest landowners - that will plant an estimated 300,000 trees over 5,500 hectares of the South Pennines in the next four years.
