Tweed Forum Invasives Project

Giant Hogweed before management at Coldstream, 2004

The Tweed Invasives Project was launched in 2002 and is a catchment scale control programme of invasive, non native plants, primarily focusing on Giant Hogweed and Japanese Knotweed. The Project is coordinated and delivered by the Tweed Forum in partnership with statutory bodies and, importantly, local farmers, landowners, fishing interests and community groups. While acting as a single point of contact for the public to report sightings, the Project also offers advice, training and practical support for the control of invasives throughout the 3,000 square miles of the Tweed Catchment.

Over the past 9 years, the Project has made huge progress towards the long-term, sustainable control of invasives, changing the lower reaches of the catchment from an area dominated with invasive plants back to a more natural ecosystem, with native riparian and woodland flora. The Tweed Invasives Project is now widely recognised as the blue print for the sustainable, long-term control of invasives and a model for partnership working.
