麻豆约拍

Japanese knotweed evolved to grow on the slopes of Japanese volcanoes.

Its harsh home makes it a thug of a plant outside its natural range with a seemingly magical ability grow in the most unlikely places.

In the more than 100 years since a few female specimens were brought to UK shores as an ornamental garden plant it has spread across the country and is now probably the most hated plant in the UK.

But is it really the Great Invader we believe it to be? Derek Mooney intends to find out.

Telling the stories of non-native invasive species and our complicated attitudes to them and with an uncertain political future, how do we police our ecological borders?
