False-acacia

(Robinia pseudoacacia)

A non-native invasive plant.

False-acacia is extensively planted in the UK and spreads mainly by suckering.

Habitat

Although it is currently uncommon in the wild it is showing alarming signs of spreading in disturbed, ruderal habitats (for example on railway lines). In France and Italy the tree is freely establishing in woodlands, much as sycamore has done here.

What's the problem

Its rapid spread, suckering nature, spiny, inpenetrable habit when established, and its ability to regrow when cut down mean that it is a major cause for concern. We have the ability to control it in the wild in Britain at the moment, but it is likely to become a major established pest in the coming decades.
