Chalara in Non-woodland Situations - TH0148

Purpose: To develop policy and practical recommendations for the Authority, in response to Chalara in non-woodland settings.

Part 1: Scale of non-woodland ash distribution.
To establish, where possible, the number and distribution of non-woodland ash trees present in the landscape.

Part 2: Problems caused by ash dieback
To examine the environmental, legal and practical problems that will result from Chalara and attempt to find solutions where possible. Experience has shown that the problems are likely to fall into broad categories, which shall be used as a framework for this part of the work.
- Habitats
- Practical management of non-woodland ash
- Tree safety
- The impact on local authorities with regard to the implementation of tree, planning and safety legislation
- Other threats and concerns

Part 3: External knowledge
A review of the impacts of ash dieback in non-woodland situations in Europe.

Part 4: The costs of Chalara
A review of the potential costs that shall be incurred as a result of this disease through detailed interviews with local authorities who are already dealing with Chalara and with the main transport agencies (Highways Agency and Network Rail) plus infrastructure companies (National Grid and the utility companies), to produce projected costs to our infrastructure that will arise from Chalara in non-woodland situations. We will also explore the strategies that they are considering to reduce the financial impact of the disease.

Part 5: Policy solutions
An understanding of the relationship between the policy framework and the impacts of Chalara as well as an appraisal of opportunities and challenges for proactive and pre-emptive policy responses to the incidence of Chalara in non-woodland trees.
