Tree Disease

Information and advice about Tree Diseases to be aware off and Dangerous Tree guidance.

Chalara Dieback

Chalara dieback is a disease that is affecting Ash trees across Europe and now parts of Eastern England, with the nearest case being located in Horncastle, Lincolnshire. Originating in Denmark, Chalara dieback is thought to have been spread by either air-born spores or cross contamination with imported trees from Europe. The Council’s advice to the public is to be aware that this is now affecting Ash trees within the region and any suspected cases should be reported directly to the Forestry Commission.

For further information and advice on Chalara dieback, please see the Forestry Commission’s Website

Severe Weather and Protected Trees

At certain times of the year, the weather can cause serious damage to trees in the form of wind, snow and frost damage. In some cases, the damage can pose a significant health and safety threat to the general public, livestock or property. When this occurs, the Council does not expect the customer to formally apply for permission to make the tree(s) safe, but it does expect that anyone who finds it necessary to undertake works to protected trees can demonstrate why these works needed to be undertaken outside the planning process.

The customer should make the tree(s) safe even if it requires full removal. However, the Council requires the person who undertook the works to complete a Protected Tree Works Exemption Notice.

For emergency works undertaken to protected trees without formal permission, please complete and return a Protected Trees Works Exemption Notice.
