The Department for the Environment has unveiled a new action plan to tackle the outbreak of ash dieback, but admits it cannot eradicate the disease.
More than 100,000 newly planted and nursery trees with ash dieback have already been destroyed, but mature trees will not be burned because they are important for other wildlife and may help identify resistant strains.
Some 129 sites are now confirmed as being infected after an unprecedented nationwide survey involving around 500 people. Fifteen of these are in nurseries, 50 in recently planted sites and 64 in the wider countryside.
Cases have now been reported in Sussex, Berkshire, Lincolnshire, Yorkshire, Bedfordshire, Northumberland, Norfolk, Suffolk, Kent and Essex. Several National Trust sites, including Ashridge in Hertfordshire, have put up signs as an extra precaution to prevent the disease spreading.
Under the latest measures, affected new and young trees will be destroyed immediately and the search for the Chalara fraxinea fungus that causes ash dieback fungus will widen to include towns and cities.
Defra officials have worked with the Forestry Commission and other agencies to find the best way to contain the spread of the disease. The public, along with foresters, land managers and environmental groups, will be told how to spot ash dieback and what to do if they find it. Experts are also searching for trees that have a genetic resistance to the disease that could provide stock for a new breeding programme.
Environment Secretary, Owen Paterson, admits it is impossible to wipe it out now that it has been found in mature trees but insists the ash can still be saved.
“If we can slow its spread and minimise its impact, we will gain time to find those trees with genetic resistance to the disease and to restructure our woodlands to make them more resilient,” he said. “We now have a window of opportunity for action because the disease only spreads in the summer.
“Wildlife and countryside groups will play a major role in minimising the impact of the disease and so will the general public, especially when it comes to spotting other areas where the disease has taken hold.”
RSPB Conservation Director, Martin Harper, said: “The plan is a vital part of stopping the spread of this disease. However, it is essential we do not divert resources away from other vital environmental services. Money must be found from central government coffers or we will simply be robbing Peter to pay Paul.”
Over 100,000 trees have already been destroyed to try to prevent the spread of ash dieback, but experts now believe the disease could be far more widespread than initially thought.
Ian Boyd, Chief Scientist with the Department for Environment, Food and Rural Affairs, has warned ministers that the disease is likely to spread across the UK by around 20 miles a year, infecting most of the country’s 90m ash trees within a decade. Mr Boyd was speaking at a meeting of the Government’s crisis committee Cobra on Friday and warned them that trees cannot be vaccinated.
Ash trees infected with the Chalara fraxinea fungus that causes ash dieback were first detected in the UK in a nursery in Buckinghamshire eight months ago. It is now infesting trees in Scotland, East Anglia and possibly Kent. The disease was confirmed in the wild last week and the Government introduced a ban on ash seedlings from infected areas from Monday.
The Woodland Trust has welcomed the ban and called on ministers to set up an emergency summit bringing together representatives from all areas of forestry, plant health and conservation to address the wider issues surrounding threats to our native trees and woods.
Meanwhile, the University of East Anglia has developed a mobile phone app for iPhone and Android which you can download from Ashtag.org. It will help you identify ash dieback and report any sitings you might find using your phone’s camera and GPS.
