We are committed to protecting our woodlands from pest and diseases, and making them more resilient.

Our tree health strategy

The key objective of the strategy is to preserve the health and vitality of trees and woodlands in Wales. It also aims to take proactive measures to reduce the impact of pests and diseases on trees and woodlands in Wales.  

We have produced an animation to show why healthy trees are essential to the people of Wales (external link).

Chalara Dieback of Ash – Response for Wales (2016)

Chalara dieback of ash is well-established across Wales and will continue to spread. Our main objectives are to:

  • help conserve the benefits of ash woodlands
  • guide and encourage landowners, citizens and industry to engage in surveillance, monitoring and action in response to Chalara dieback of ash
  • build economic and environmental resilience to this and other pests and diseases.

Ash Dieback is a serious disease of ash trees caused by a fungus. The disease causes leaf loss and crown dieback in affected trees, and it can lead to tree death.

Phytophthora ramorum

The Phytophthora ramorum in Wales - disease management strategy deals with the management of the fungus-like organism Phytophthora ramorum with emphasis on the impacts of the pathogen on Japanese, Hybrid and European larch. It is part of a series of strategies for tree health in Wales and it sets out:  

  • the background to the disease, the current level of infection and its impact in Wales
  • the options considered and rationale for establishing a Phytophthora ramorum strategy in Wales
  • the strategy itself, the regulatory mechanisms and the areas where additional funding may be required.
