More than a dozen elm trees are having to be destroyed after becoming infected by a logpile which became a breeding ground for elm beetles.
Council tree experts became aware of a concentration of affected elms in the Westbourne Street area of Hove last week.
After an extensive search of the area they found the pile of logs on private land, which has now been destroyed.
A council spokesman said: “Unfortunately 14 trees are having to be destroyed. Our tree experts are dealing with this outbreak as a matter of urgency.”
Ward councillor Tom Bewick said: “It’s a real pity that the area around Westbourne Street will be losing some really beautiful elm trees.
“However, I would like to give credit to the council’s city parks team for locating the source of the disease quickly – found to be in a private dwelling where the infamous beetles were breeding.
“At least this environmental action will protect all the other trees and ensure that residents continue to enjoy living in one of the leafier parts of the city.”
Resident and former councillor Chris Hawtree said: “I was desperately sad to learn that elm logs left for two or three years on St Christopher’s School have fostered beetle which has killed trees on my road, and put at risk those within a one kilometre circle.
“I sit upstairs and have always looked out at them with joy. It is exhilarating to look at the long vista of elms. Magical.”
Earlier this year, two more trees in Queen’s Park, Brighton were destroyed after showing signs of infection, which include
Brighton and Hove is host to the National Elm Collection, partly because of its excellent track record in elm preservation.
Whenever residents have work carried out on elm trees it is vital that the material is deposed of correctly by competent tree surgeons or gardeners.
Also, when purchasing fire wood residents should always check with the supplier that it contains no elm wood.
