The search is on for a flock of sheep to provide an environmentally friendly lawn-cutting service in East Yorkshire.
The Environment Agency wants to see sheep grazing on the land
The Environment Agency came up with the idea of using sheep to graze on 10 acres of land at Barmby Barrage, near Goole, in a bid to save time and money.
It currently costs about £2,000 and takes up to 180 hours to cut the grass at the tidal barrage on the River Ouse.
The agency said it hoped leasing the land to a local sheep farmer rent free would be mutually beneficial.
Dennis Garner, the Environment Agency's site controller at the barrage, said the size of the land meant it took a lot of time and energy to maintain.
"It's the perfect solution all round really," he said. "We get the grass cut for free, the farmer gets the grazing land for free."
Barmby Tidal Barrage was built in 1974 by the then Yorkshire River Authority where the River Derwent joins the River Ouse to exclude the tide from the lower part of the River Derwent and safeguard water for domestic supplies.
