Work has started on a £35,000 scheme to remove more than 200 trees stricken by ash dieback in the Ribble Valley.

The diseased trees will be felled at the Crosshill and Salthill Quarry nature reserves in Clitheroe, and the Whalley Moor Community Woodland.

Around 165 dead or dangerous trees will be felled at Crosshill, 35 at Whalley and one at Salthill.

Ash dieback arrived in the UK about 20 years ago and is becoming prevalent in public sites, and it looks set to have a more devastating impact than Dutch elm disease, which killed 25 million trees in the 1970s and 80s.

The fungal disease leaves Ash trees at risk of collapse or shedding branches in public areas, such as paths and playgrounds.

Cllr Stuart Hirst, chair of Ribble Valley Council’s community services committee, said: “We have been managing the impact of ash dieback for a few years on numerous sites across the borough and removing dangerous and dying trees where needed.

“But we have identified three priority areas in Clitheroe and Whalley, where a significant number of ash trees are dead, dying or in a dangerous condition, and urgent action is necessary in order to protect the public and property.

“Works at Salthill are largely complete, with only one tree left to be removed, which will require specialist equipment and sensitive handling of a power cable.

“Works at Crosshill and Whalley Moor will start this week by specialist tree contractors to minimise the impact on footpaths, biodiversity and infrastructure.

“We have liaised with the Lancashire Wildlife Trust, which manages Crosshill and Salthill, and the Friends of Whalley Moor Woodland, who are aware of the need for and extent of the works.

“We are asking members of the public to bear with us during this difficult and sensitive work, which we hope to conclude as soon as possible.”

Once the trees have been felled, Ribble Valley Council will devise a replanting programme in consultation with community and environmental groups.

Parts of the felled trees will be left in-situ to rot, creating a habitat for animals, insects and fauna.
