A group in County Tyrone says it has made progress in tackling giant hogweed, the toxic invasive plant often labelled one of the UK's most dangerous species. The work highlights the continuing effort to control a plant that poses risks to people and can spread aggressively in the landscape.

Giant hogweed originates from Asia, but it has been present in Britain and Ireland since the early 19th century. It was first brought in as an ornamental plant, before becoming established far beyond garden settings.

Because giant hogweed is toxic, clearing it is treated as a serious task. Campaigns against the plant focus on limiting its spread and reducing the danger it can create in affected areas, especially where communities may come into contact with it.

The update from County Tyrone suggests local action can make headway against the invasive species. Even so, the history of giant hogweed in Britain and Ireland shows why long-term control remains important.
