Non Native Invasive Flora out compete our native plants, can damage riverbanks and landscapes, can increase flood risk and reduce habitat availability for native wildlife. They can sometimes also be a danger to members of the public and damage infastructure.


MVCP have been managing the Giant Hogweed and Invasive Flora Control Programme in the Medway Catchment now for over 14 years!

The project has expanded from treating hotspot areas to treating the entire catchment and we currently cover almost 200km of riverside land, including the River Cray in Bexley.


The project is funded by the Environment Agency, DEFRA, Maidstone Borough Council, Tonbridge and Malling Borough Council, Yalding Parish Council and via landowner contributions. Via this support we treat around 10,000 Giant Hogweed plants a year. As well as this species MVCP also address other invasive non native flora where required. In recent years we have been treating and monitoring Floating Pennywort on the Medway and Water Fern on the Beult and adjacent to the Medway. We also address some riparian areas of Japanese knotweed.

With the help of volunteers we also pull up thousands of Himalayan balsam plants each year helping to reduce areas in risk of flood due to plant abundance. At the moment we are also hoping to work with CABI on Himalayan balsam Bio-Control.


We rely on landowner consent and permission, so if you live by the river and have a problem with invasive non native flora please get in touch. We might not always be able to include your land or treat the plants in questions, but if it's Giant Hogweed or another of the target species we address we'd welcome hearing from you and can offer advice, support and often direct control.


If you'd like to volunteer to survey for invasive plants or to help pull areas of Himalayan balsam, please get in touch. For more information on MVCP's project download the PDF newsletters, I.D factsheets and Annual Reports at the bottom of this page.
