INNS control in the Tamar Valley
In advance of Invasive Species Week 2022, the Tamar Valley National Landscape and its partners in the Tamar Invasives Group, with the support of the South West Lakes Trust, held an event at the Tamar Valley Centre. We looked at lessons learnt from the Tamar Valley Giant Hogweed Eradication project and also focussed on Japanese knotweed and Himalayan balsam in the National Landscape and wider catchment.
The Tamar Valley National Landscape and our partners in the Tamar Invasives Group, are grateful for the financial support we have received over the years to make this work possible, including a Water Environment Grant 2021 and contributions from South West Water.
Current Activities
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.
With support from the Local Invasives Management Fund, we are currently looking at the feasibility of extending our management programme to other INNS plants, with a particular focus on riparian areas.
