INNS Control in the Tamar Valley
Giant hogweed management
Through the Tamar Valley Giant Hogweed Eradication project, with the support of over 90 landowners, we have carried out the annual survey and control of Giant hogweed along a 45mile stretch of the Tamar and lower Lyd rivers (both Devon and Cornwall banks) since 2001.
Our aim – to see the eradication of Giant hogweed from the Tamar catchment.
American skunk cabbage management
With support through the Farming in Protected Landscapes programme, in 2024 we initiated the survey and control of American skunk-cabbage in the Giant hogweed project area.
INNS management in the Tamar catchment
The impact and necessity of controlling invasive non-native species (INNS) is well-documented and addressed through various local and national plans, strategies, and legislation.
A feasibility study has been conducted to explore potential INNS management in the Tamar catchment, focusing on Japanese knotweed, Himalayan balsam, American skunk cabbage, and the ongoing Giant hogweed control program.
Despite the widespread presence of knotweed and balsam, the report advocates for control measures and provides implementation suggestions. e hope this work will significantly contribute to addressing the spread of INNS across the catchment and look forward to collaborative efforts to tackle this growing challenge.
We wish to thank those who supported and contributed to this work. This project was funded by Defra’s Local Invasives Management Fund
