Bere Marsh Farm has saplings of the species that it hopes to share with "those eager to help".

Conservationists are calling for people to use cuttings from one of UK’s rarest native timber trees to help save the species.

Cuttings of the black poplar have been cultivated at Bere Marsh Farm, near Shillingstone, Dorset.

The farm, which is owned by the Countryside Regeneration Trust (CRT), said there were only about 7,000 black poplar trees in the country.

Jenny Ashdown, from the trust, said saplings were “ready to be shared with those eager to help”.
