Our river banks are under invasion, although attractive with its pretty pink flowers, Himalayan Balsam is destroying the diverse habitat of your local river. This plant is spreading quickly and excluding around 30 native species from their habitat along our rivers.

The Lincolnshire Rivers Trust is working with the Environment Agency to eradicate this non-native plant from the River Witham but we need your help.

If you spot Himalayan Balsam (or Giant Hogweed or Japanse Knotweed) when you are out and about let us know.


Himalayan Balsam

Himalayan Balsam

This pretty purplish-pink to white flowering plant was introduced as a garden plant in the early 19th century and first recorded in the wild in 1855.

Japanese Knotweed

Japanese Knotweed

This plant, originally from Japan, was considered to be a rare species, it was first introduced as an ornamental plant in parks and gardens and first recorded in GB in 1886.

Giant Hogweed

Giant Hogweeed

Native to Caucasia and Central Asia, the plant was introduced to Britain as an ornamental plant in the 19th century. First recorded in 1828 it closely resembles our native Cow Parsley.
