Pebmarsh Brook 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

Signal Crayfish have been most recently recorded on this water body in 2003 and 2007. Signal 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 Signal Crayfish, regular monitoring is needed to ensure a strategic approach when a solution has been identified.

 

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 programmes.

 

There is currently no data but it is very lilely that there will be some non native invasive species present in this brook.

Investigate the presentce of non native invasive species.
