Ash dieback disease found in Nottingham

Ash Dieback

40,000-50,000 trees in Nottingham could be affected by Ash dieback disease in the next 3-5 years after the disease was found along the Colwick Loop Road. The County Council is seeking to obtain  £500,000 from the transport and highways committee to tackle the problem.

Ash dieback or Chalara,  as it is also known, causes leaf loss, crown dieback and bark lesions in infected trees. Once a tree is infected the disease is usually fatal, this can be directly, or indirectly as the tree is weakened making it vulnerable to other pests or pathogens, in particular Armillaria fungi, or honey fungus.

It is expected that 80 per cent of trees on the A612 will be felled, around 5,000 in order to hopefully combat the spread in some way. The disease is airborne and carried by spores and can travel tens of miles by wind. It can also be spread over longer distances through the movement of diseased ash plants. Movement of logs from infected trees might also be a pathway for the disease, although this is considered to be a low risk.

The agent which causes Chalara dieback of ash is treated as a quarantine organism under national emergency measures and any suspected sighting must be reported.
