Ash dieback is impacting rural and urban landscapes and ecosystems. Current evidence indicates that at least 50% – 75% of Scotland’s approximately 11 million mature ash trees could be lost to this disease over the next two decades.

a) Environmental impacts: Ash trees play an important role in Scottish ecosystems, and support many other species such as invertebrates, birds and lichens. Ecosystem continuity is a key concern for the long-term recovery of affected landscapes.

b) Financial impacts: Current estimates suggest that ash dieback could potentially cost Scotland in the range of £4 million - £20 million per annum as the disease progresses.

c) Other impacts: The safety of arboricultural and forestry professionals as well as the public is a central emerging issue, as ash dieback and associated secondary pathogens can lead to tree brittleness, potential branch shedding and root weakness. Priority needs to be given to ash trees showing significant health issues in higher risk locations such as near public roads, paths, railways and utilities infrastructure.

i) Action Scottish Government is taking:

Scottish Forestry convened the Ash Dieback Risk Group in January 2020. The group, which brings together expertise from local authorities and sectors such as forestry, transport, utilities and nature conservation, was formed to provide a forum for sharing experience and coordinating actions, and to help advise the Scottish Government on policy development relating to the management of ash dieback.

ii) Support the Scottish Government has offered to relevant stakeholders, including local authorities, to deal with ash dieback:

Scottish Forestry has worked with The Tree Council to produce a Scottish Toolkit for Ash Dieback Action Plans to help Scottish local authorities, public bodies and other large-scale land owners and managers to prepare their own Ash Dieback Action Plans in response to the inevitable safety and environmental issues that affected trees will create.
