‘Conservation grazing’ has been previously successful in improving heathland habitats and biodiversity in areas like Sorel Point and Devil’s Hole, according to the team.
Bracken currently covers extensive areas of the north coast, hindering the growth of other plant species and reducing habitats for insects and birds.

Because the invasive plant is difficult to control by hand, the team want to introduce a flock of sheep to graze and trample on it to open up the scrub landscape.
There will still be access to the area as long as dogs are on leads. An alternative route will be available for those who want to bypass the sheep.
Natural Environment Manager Tim Liddiard said: “The aim is to revitalise biodiversity in the area, replacing seas of bracken with coastal grasslands, heather and gorse which are much richer.
“This will create an ecosystem that will support diverse plants and offer improved habitats for animals and birds, while also having benefits on a visual scale.”
He explained that until the 20th century, cattle, ponies and sheep would have grazed on the northern headlands and that gorse and bracken would have been collected for fuel and bedding respectively.
Today such practices no longer take place, meaning that bracken and scrub have encroached, causing some coastal and heathland species to become extinct locally.

“We want to restore the area using the same traditional methods of controlling vegetation,” he said.
On Saturday, parishioners had their say on the idea at a public drop-in at St Ouen Parish Hall.
Mr Liddiard said: “The response was really positive, with lots of different interest groups present with different needs and expectations.”
