Roman River 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

American Mink have been most recently recorded on this water body in 2013 . American Mink cause a wide range of problems on a river, including playing a large part in the local extinction of many natural species such as water voles and kingfishers.

In order to eradicate mink, they must be trapped and dispatched. Trapping must be done catchment wide as mink can travel large distances. It is important that there are enough people involved in a trapping project to ensure that the traps can be checked regularly. Monitoring mink, water vole and otter presence on your river can also help us when planning eradication programmes.

 

Himalayan Balsam has been most recently recorded on this water body since 2011 in an extensive area. 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 since 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.

 

Flood protection structures and sediment management techniques are having a negative impact on the ecology of this water body. In particular, although eel populations seem to be increasing, fish populations are suffering.

Flood protection structures must remain in place but improvements to make them more 'natural' should be investigated.

Sediment is regularly dredged from the river due to increased sediment loading. The methods used for this sediment management should be reviewed to ensure that they are more sensitive to fish populations.

The middle reaches of this water body must be maintained and used to model habitat improvements for upper and lower sections.

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.
