Dealing with invasive non-native plant species (INNS)
An invasive species can be any kind of living plant organism that has been introduced outside its natural range and can cause harm. Landowners have a responsibility to control any invasive weeds. Although it is not a legal obligation, they grow and reproduce quickly.
Some of the most common INNS found in Allerdale include:
Japanese Knotweed can damage concrete, tarmac and brickwork and impact on biodiversity. It spreads by underground roots - very small pieces of root can produce new plants.
If you come across Japanese Knotweed growing on public land, you can report it to us online using our general enquiry form below.
Himalayan Balsam is the largest annual plant in Britain, growing up to 2.5m high from seed in a single season. It is particularly common along watercourses and spreads rapidly.
Similar to Japanese Knotweed, this INNS is a large, thicket-forming plant, reaching up to 2m tall. It can be found on stream sides, hedge banks, woodland edges, roadsides, railway banks and waste ground.
Giant Hogweed can grow up to 5m tall, and the stem and leaves can cause severe skin irritation and blistering.
Where can I find more information?
- More information on the best known culprits, resident responsibilities, and how to treat INNS can be found on the Government website.
- The Environment Agency have written guidance notes for managing INNS
- The Non-Native Species Secretariat also provides a wealth of information that can advise on how to deal with INNS
