The National Programme is researching control methods and developing guidelines for good practice. These guides summarise standards expected for safe wilding conifer control.
The following guides are available:
Aerial spraying by helicopter boom (AFSA) can be a cost-effective way to control large areas of dense wilding conifer infestations.
Updated December 2021 to include guidance on managing water contamination risk and water sampling. There are further minor updates listed on page 3.

Cut stump is a control method that involves cutting a tree down and applying herbicide to the cut stump to prevent regrowth. It is suitable for the control of trees which are accessible from the ground and where the risk of damage to surrounding vegetation is minimal or not a concern.

The ABBA method of wilding conifer control involves chemically ring-barking trees by using a wand to apply herbicide from a helicopter. Dead trees are left standing until they naturally rot away. It is the most efficient way to control scattered wildings in difficult-access areas or within high value vegetation.
