Invasive non-native plant species can cause substantial environmental damage, cost millions of pounds to tackle annually and reduce biodiversity.

They can be vigorously growing plants which can:

  • out compete native vegetation
  • harbour vermin
  • collect litter
  • obstruct drainage channels or sight lines
  • increase the risk of flooding 
  • increase erosion of the riverbank.
