Exclusion zone in New Forest after discovery of sudden oak death

Tree chiefs have called in the Government and created an exclusion zone after discovering outbreaks of sudden oak death on rhododendrons.

Bushes in the Tall Trees Trail of the New Forest were recently found to be diseased with Phytophthora ramorum - known in the US as sudden oak death.

Mike Seddon, deputy surveyor for the New Forest, said: "We are now working with Defra to determine the exact scale and extent of the outbreak."

Seddon said teams would destroy infected plants, and to prevent the disease spreading visitors were being told to stay on footpaths and keep dogs on leads.

Experts would survey an area within 3km of the outbreak to look for other infected plants, said Seddon.

Seddon said despite the sudden oak death nickname, Phytophthora ramorum posed little risk to the New Forest's oak trees.

"Phytophthora ramorum got its nickname because it killed significant numbers of tanoaks and native American oaks in America, which are not a true oak species.

"However Britain's two native oak species, sessile and pedunculate oak, have proved much less susceptible than their American cousins.

"British native oaks only become infected if they are standing very close to heavily infected shrubs such as Rhododendron ponticum.

"There is, however, evidence that other species like beech and ash are susceptible. Our approach therefore is to find out exactly the extent and severity of the outbreak.

"We then destroy the infected shrubs and plants to minimise the risk of the infection spreading into the New Forest's trees."

Phytophthora ramorum was first found in Great Britain in 2002, and since then a number of outbreaks have been detected in England, Scotland and Wales.
