Bollin Giant Hogweed Control Programme

Giant Hogweed is a problem in the Bollin catchment, but luckily it only affects the downstream extent of the River Bollin itself, and so we have the opportunity to be able to control this invasive non-native species throughout its range. 

Giant Hogweed is not only detrimental to wildlife, as it creates massive monocultures easily out competing native flora, it is also dangerous to people as the sap from this plant can cause chemical-like burns when in contact with skin.

This year, thanks to Environment Agency funding, 11 volunteers were trained to use herbicides by water, and with all having passed the course, we have greatly increased the capacity of the project.  This means we can finally tackle one of the areas badly affected by Giant Hogweed is Heatley at Lymm, and so volunteers and partners from other organisations are concentrating their efforts in this area to try and control the historically dense populations of Giant Hogweed here. 

Farmers are contributing towards the costs of this work in order to ensure that we can continue with our control work programme in the coming years.  Giant Hogweed, and indeed all invasive non-native species, cannot be successfully eradicated in one year, and it takes a few years of control and careful monitoring before an area can be declared free of invasives.

Our control programme links in with the work other landowners, interest groups and local organisations are doing to control Giant Hogweed on their land upstream of Heatley through to where the first Giant Hogweed plant can be found in Wilmslow.  Without this co-ordination of effort the project would not be successful.
