Ash Dieback Is Now Widespread in Cumbria
Carlisle Tree Surgeons arranges ash dieback management across Carlisle, the Eden Valley and the surrounding towns, carried out by NPTC-qualified, fully insured tree surgery teams.
Hymenoscyphus fraxineus — ash dieback — is present across Cumbria and the rest of the UK. Ash is one of the commonest trees in the hedgerows, field boundaries and riverside woods around Carlisle, and most ash trees will decline over the coming years. Infected trees become brittle, making them dangerous to climb and dismantle once decay sets in.
For landowners with ash near roads, footpaths, car parks or buildings, that means a duty to assess and manage the risk. We help you do it in a planned, budgeted way rather than as a series of emergencies.

Plan Now, Fell Less Later
Not every infected ash needs removing straight away. Trees are graded by canopy loss, and those away from targets can be monitored while resources go to the ones that pose a real risk.
Where felling is required, our teams use MEWPs and rigging techniques suited to brittle timber, and we advise on replanting so the landscape recovers. Larger fellings on farmland or in woodland may need a Forestry Commission felling licence, which we can tell you about when we quote.

Ash Dieback Management: Common Questions
How can I tell if my ash tree has dieback?
Look for diamond-shaped lesions on the bark, wilting black leaves in summer and bare, dead twigs at the tips of the crown. Heavily infected trees often sprout clusters of new shoots along the trunk.
Does every infected ash need felling?
No. A small proportion of ash show tolerance to the disease. Trees away from roads, paths and buildings can often be left and monitored.
