River Brain Pressures

The table below shows the current pressures that this waterbody faces and the solutions that could be put in place to solve these problems. You can learn more about some of these pressures and solutions on the Environment Agency Catchment Data Explorer or you can contact us to find out more.

PRESSURES

SOLUTIONS

Himalayan Balsam has been most recently recorded on this water body in 2013. This pretty plant, with pink flowers, is fast growing and hardy. It covers river banks and shades out native plants. In the winter, Himalayan Balsam will die down, leaving bare banks that are susceptible to erosion.

 

Himalayan Balsam can be removed easily by pulling it from the ground (including the root), snapping the basal stem and then leaving it in a pile to rot down. If you would like to get involved in pulling this invasive species, or would like to organise a work party, then please let us know through the contact us page.

 

Japanese Knotweed has been most recently recorded on this water body in 2007 and 2012. This plant not only shades out native plants, but also causes serious damage to buildings.

Japanese Knotweed can be removed by spraying or injecting its roots with pesticides, this takes time to kill the plant, but it is effective. Just digging up this plant is, unfortunately, not enough.

 

Floating Pennywort has been most recently recorded on this water body in 2012. Floating Pennywort covers the surface of the river, blocking out natural light and causing the plants below to die. The dead plants then rot down, removing the oxygen from the river. Floating Pennywort also causes trouble for boats, making the river very difficult to navigate.

Eradication of floating pennywort can only be successful through spraying. It spreads very quickly and just small live fragments can allow it to take hold again. If you see this plant species then please alert us as soon as possible.

 

This water body has developed problems with phosphate levels which contribute to its overall rating as poor. Unfortunately there is no data to suggest where these problems are originating from.

Carry out further investigation in order to determine the source of pollutants and take the action required to solve the problem.
