From The Yorkshire Times.
The Yorkshire Invasive Species Forum, a partnership between Yorkshire Wildlife Trust and the Calder & Colne Rivers Trust, has been working to control invasive plant species in the region, including giant hogweed, which has seen widespread media coverage following injuries inflicted on members of the public who come into close contact with the plant.
As giant hogweed and other invasive plants begin to flower and treatment is in full flow, Yorkshire Wildlife Trust is alerting the public to the dangers of these non-native plants and asking for sightings to be reported.
Invasive species are those that have been introduced outside their normal habitat range, often due to human action. This is particularly true of two of the best known invasives: Japanese knotweed and giant hogweed, which were both introduced as ornamental plants during the 19th century.
