A National Trust estate is facing a hay shortage as grass growth has stalled in drought conditions, with livestock forced on to winter feed months early.
Hay meadows that normally produce 150 tonnes at Wimpole Estate in Cambridgeshire have yielded nothing, the conservation charity said.
It is the third time in five years the estate has faced severe drought impacts and in response conservationists are accelerating a programme of climate adaptation.
This includes tree planting, work to increase rainwater storage, and conservation grazing to reduce wildfire risk and support habitat restoration.
The National Trust said selective breeding is also helping livestock cope better with dry conditions.
Dave Hassall, National Trust farm and countryside manager, said: “Drought affects every part of the system – crops, grassland, livestock, wildlife and costs.
“We’re already using winter feed because summer growth simply hasn’t happened.
“These pressures are being felt across all farming systems, and they show why adapting to a changing climate is essential for food production, nature and rural communities.”
The National Trust said Wimpole Estate is its largest organic in‑hand farm, with 1,200 hectares (3,000 acres) of land.
Grain yields are down by around 25%, and straw production has fallen from 200 bales to just 60.
Wildlife habitats are under pressure, with invasive species such as ragwort and thistles spreading rapidly in the dry conditions, and soil health has suffered with cracked ground.
Veteran trees are showing signs of stress, and disrupted weather patterns are creating mismatches between flowering plants and pollinating insects – with consequences for both biodiversity and food production.
Efforts are under way to help the estate adapt in the face of climate change, with 125,000 trees planted since 2021 to improve shade, soil health, moisture retention and habitat resilience.
The estate is trialling alternative forage sources such as willow and aspen, and exploring more drought‑tolerant crop varieties.
Mr Hassall said Wimpole Estate “has adapted for 2,000 years” and “that spirit continues”.
He added: “We welcome recent Government support for farmers, but long‑term resilience requires sustained investment in nature and climate adaptation.
“We cannot do this alone.”
The National Trust is calling on the Government to make climate resilience a national mission, led at Cabinet level, to invest in nature as essential infrastructure, and to support fire and rescue services.
