River Wid - Margaretting to River Can 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 2012 . 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.

 

American Mink have been most recently recorded on this water body in 2009 . 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

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.

The invasive signal crayfish are present in this waterbody. The signal crayfish could potentially cause problems for invertebrates in the future.

There is currently no known method of dealing with signal crayfish, the only next step would be to monitor and manage the population.
