Lower River Stour 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

Giant Hogweed has been most recently recorded on this water body in 2015. This plant has been in the news a lot more recently due to the horrific burns that its sap can give the skin. This invasive plant is so large that it is able to shade out other native plants.

Giant Hogweed MUST be removed by a professional ONLY. The plant is sprayed off and then removed in a safe manner. If this plant has already been removed from this waterbody then please let us know, if it is spreading further then get in touch.

 

Turkish Crayfish have been most recently recorded on this water body in 2007, 2009, 2011 and 2015. Turkish Crayfish cause changes to the natural bankside habitat and also out-compete our native crayfish. They are fierce predators and can completely change fish and invertebrate communities so that they are no longer in their natural state.

There is currently no known solution to the invasion of Turkish Crayfish, regular monitoring is needed to ensure a strategic approach when a solution has been identified.

 

A range of measures have previously been put in place for this waterbody, to improve the bankside vegetation, remove hard bank reinforcements, increase channel diversity and remove structures. These measures have not been taken forward.

Take forward previously outlined measures in order to increase habitat and reduce barriers to flow and fish.

Multiple physical structures cause barriers to fish, this includes a section of water impoundment.

Take forward solutions stated under physical modification.

Multiple physical structures and a lack of in channel vegetation have caused un-natural flows. This could be having a negative impact on the biology of the waterbody.

Take forward solutions stated under physical modification.

This waterbody 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. This waterbody also has problems with its invertebrate populations; this may be linked to the high phosphate levels.

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