Since 2021, Forestry and Land Scotland (FLS) have worked with the Alliance for Scotland’s Rainforest to identify landscapes where they can work co-operatively with other land managers to effectively control rhododendron at the landscape scale. FLS accounting systems do not differentiate rhododendron control from other environmental expenditure such as Invasive Non-Native Species control. Therefore, it is not possible to provide exact figures of expenditure on a) removal and b) control of Rhododendron ponticum in each year since 2020-21. However, between 2022-23 and 2024-25 £1.685 million was spent on INNS and rhododendron removal and follow-up control in priority rainforest areas. During the current financial year, £1.397 million has been made available for INNS and rhododendron control.

Scottish Forestry has agreed £1.793 million of grant support for the eradication of rhododendron since the 2020-21. The funding provided is to support works that secure the removal of rhododendron from the funding area.

In addition, a number of Nature Restoration Fund projects aimed at improving and restoring areas of Atlantic rainforest include rhododendron control and removal. NatureScot does not hold precise information on the elements of those project costs that are solely directed at rhododendron control, but the total of the awarded costs of these projects from 2020-21 to 2024-25 is £1.734 million. The total of the awarded costs for 2025-26 is £1.322 million.
