Map reveals locations of toxic giant hogweed in Warrington

Giant hogweed is highly dangerous, with its sap damaging skin on contact, and it can leave people with scars as a result.

Dozens of reports of the plant have been made in Warrington over recent years, and with more people venturing out for walks as the weather improves, the chance of bumping into it has escalated.

But you can prevent this from happening thanks to this handy map devised by WhatShed.

Originating from southern Russia and Georgia, the plant can reach more than 10ft in height, and despite appearing harmless on first sight, it causes a serious risk to humans.

The Royal Horticultural Society states: “Although an impressive sight when fully grown, giant hogweed is invasive and potentially harmful.

“Chemicals in the sap can cause photodermatitis or photosensitivity, where the skin becomes very sensitive to sunlight and may suffer blistering, pigmentation and long-lasting scars.

“Their occurrence is monitored, and it appears that they are reported to be continuing to spread and can be found in every part of the British Isles.”

As can be seen from the map, the plant is growing across central and southern Warrington, with other reports occurring in Sankey Bridges and Croft.

When previously asked about giant hogweed in the town, Warrington Borough Council said: “It is the landowner's responsibility to control these plants.

“But please make sure to read about how best to control them through sources such as the Royal Horticultural Society, as they can cause skin irritation if you come into contact with them.

“If giant hogweed is identified on private land, for example a neighbouring property, a construction site or agricultural fields, the landowner should be contacted in the first instance for them to remove it.

“Where giant hogweed is identified on council land, a programme of herbicide treatment is implemented in line with the Environment Agency’s guidance to eradicate the plant.”
