Giant Hogweed removal

Giant Hogweed (Heracleum mantegazzianum) has been reported at Duton Hill. This invasive non-native species can produce 20,000 seeds from a single plant and is therefore capable of spreading rapidly. It also poses a risk to human health. This is currently a small project to tackle - help us tackle this area before the small problem turns into a big one!

Giant hogweed looks similar to native hogweed, but is much larger and can shade out native vegetation and leave bare ground exposed over winter. It should not be tackled without specialist help as the sap can cause severe photosensitivity and blistering of the skin, sometimes lasting for several years.

This project was started in 2014 by the Environment Agency. The giant hogweed was destroyed and its extent has now reduced. If you come across any Giant Hogweed in your area then please let us know!
