Jersey group plan to protect stone age site
Work is being done by the Societe Jersiaise to protect a stone age site at Noirmont headland in Jersey.
The historical group believe the mound dates back about 4,000 years and say it is an important part of the island's archaeological history.
They are concerned the roots of oak trees that surround the site could be damaging the ancient foundations.
John Clarke from the Societe Jersiaise said the trees would have to be removed.
He said: "The trees grow and first grew about 1946 and I think they would have been cleared away about 1970 but we now have 40ft trees with invasive roots.
"Most of them are evergreen and they leave the ground underneath completely bare to other forms of erosion."
