A team from Guernsey Conservation Volunteers has been helping restore sand dunes in Alderney.

The 15-strong team joined the Alderney Wildlife Trust to remove sour fig, which is thought to have been introduced after World War Two to cover wartime bunkers, but posed "a significant threat to the island's delicate dune systems", the trust said.

The volunteers removed an estimated 13m-cubed of the heavy fast-spreading invasive plant which carpets and weakens marram grass if left unchecked.
