Invasive Plants

An invasive plant is an introduced species ( not native to a specific location) that has the ability to thrive and spread aggressively causing damage to the environment, human economy and/or human health. A naturally aggressive plant may be especially invasive when it is introduced to a new habitat. Invasive non-native species are now widely recognised as the second biggest threat to biodiversity worldwide.

Japanese Knotweed

Japanese knotweed is an invasive plant species that is rated among the 100 worst invasive alien species in the world.

Himalayan Balsam
