River Crouch - Cray's Hill to Wickford 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

Japanese Knotweed has been most recently recorded on this water body in 2010. 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.

 

American Mink have been most recently recorded on this water body in 2008 . 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.

 

Phosphate levels within this waterbody are considered to be too high and therefore have a 'bad' classification. The point source inputs need to be identified although there is a sewage treatment works that discharges into this waterbody.

Identify point source inputs.

Ensure that sewage effluent standards are maintained.

Run off from agricultural land and urban areas have contributed to this waterbody having problems with phosphate.

Engage landowners to encourage best practises for use of phosphates.

Increase riparian buffer strips to encourage nutrients to settle out before entering the river.

Investigate the use of sustainable drainage systems (SuDS) in urban areas.
