Our Stretch Target


What will I use the extra money for?

We will use additional money to set up community groups to take on a regular monitoring and capturing programme to ensure that there is a legacy to the project and that the work can continue. 


We are the Norfolk Rivers Trust and we need to raise £1000 so that we can trap non native species that threaten our native species and the health of our rare chalk rivers. 

The Norfolk Rivers Trust was established in 2011 with the objective of conserving and restoring Norfolk rivers and wetland habitats.

The Trust based on the Stody estate in Norfolk is run by a committee of trustees and officers with a broad range of expertise in river habitat conservation, land management and conservation, charitable trust, legal and business administration, compliance and accountancy. The Trusts mission is to enhance the value of the aquatic landscape through encouraging natural processes, with benefits for wildlife and people. You can find out more about the Norfolk Rivers Trust on the website at 

Invasive species pose one of the most serious threats to biodiversity worldwide second to habitat loss. It has been estimated that the damage caused by non native species accounts for 5% of the world economy, in Britain alone £2 billion a year.  Non native species in our rivers is a problem that threatens to undo all the good work that has been happening. Species such as Red Signal Crayfish are an aggressive alien species that can kill our native White Clawed Crayfish and destroy river banks. There has also recently been sighted a Mitten Crab for the first time in the river Glaven which if numbers increase would do significantly more damage than Red Signals. Himalayan Balsam and Floating Pennywort smoothers the river bed and changes the habitat that our native fish species need to lay eggs and migrate.

This is a small part of the story and research is being pulled together to get a better picture of these aliens and the extent to which they have spread. What is desperately needed is focused intervention and practical work to remove these species and stop the damage before it is too late. 

The Norfolk Rivers Trust is still a fairly new charity and we are completely dependant on funding. No funding means no Trust. And no Trust means our rare Norfolk chalk rivers will degrade. We regularly try to get money from the government, charitable trusts and national funding initiatives but this is by no means easy as we compete with everyone else and are completely dependant on the wishes of our funders. crowdfunding will enable us to see how people on the street see our work and what it means to them. 

This money will be used to purchase and install traps and equipment to keep invasive species out of the rivers. 

As a reward we will offer a thankyou on our website and prizes ranging from wildlife pictures, a signed copy of Silt Road, half a days walk along a river, electrofishing, and for big backers a boat trip fishing for bass. 

You can find out more about the team on the website but we have 4 officers with backgrounds in river restoration, ecology and fisheries. This team will be well placed and more than qualified to deliver this project. 

If you have any questions about the funding please contact the project owner or ring the office at 01263 862657
