Conservation experts have vowed to continue fighting to save the UK's last remaining elm trees from a devastating disease - and they are calling on volunteers to help out.

Although the majority of the trees died out in the 1970s with the outbreak of Dutch Elm Disease, around 60,000 English Elms remain between Shoreham and Eastbourne.

It is now the only significant population in the country.

To deal with the ongoing problem of Dutch Elm Disease, the South Downs Joint Committee (SDJC) constantly monitors the endangered species with a continuous programme of disease control.

To do this it urgently needs a constant flow of members of the public willing to give up their time to help identify and deal with diseased trees.

The work of an elm warden involves regular walks through the summer months, looking at trees and reporting back any which look diseased.

Last year it was reported that budget cuts threatened the future of the endangered tree. With finances for programmes to halt the spread of the disease under threat, there are fears that the survival of the elms could now be in danger.

An independent review into the situation is underway and no results are expected for several more months.

Countryside manager Phil Belden said: "The Dutch Elm Disease programme is about more than money. We undertake a proportion of the work in East Sussex and we want to make sure that this activity is well co-ordinated and properly thought through.

"We are working with partner organisations, including Natural England and the Forestry Commission, to develop a strategy for the future, which will be informed by thorough research.

"Our work in conserving the South Downs is important and, as the Dutch Elm Disease season starts we will continue our battle against the beetle. As in previous years, we really appreciate any time local people can give."

Elm Disease is caused by a fungus and is one of the most virulent tree diseases known.

The fungus invades the water transport systems of the trees causing them to die.

Spread of the disease occurs in two ways: from tree to tree via root connections and over greater distances by the elm beetle, which feeds in the branches and then breeds beneath the bark.

The main method of control is the felling of diseased trees to prevent beetles from breeding. Sometimes, prompt removal of diseased limbs is sufficient to save the tree.

Elm wardens will be given full training at the beginning of June. For more information call 01273 698256.
