I am a masters student from Queen Mary, University of London and am currently starting my Thesis on the effect of Signal Crayfish on riverbank erosion (due to their burrowing activities). I have developed a Crayfish Impact Assessment Form which I am hoping to conduct on as many reaches with crayfish burrows as possible. I have been to several sites on the Thames catchment suggested to me by the Environment Agency, however did not have much luck in finding any burrows.

I thought this would be the best place to come to try and find people who know of river reaches with abundant signal crayfish burrows. If anyone knows of any rivers in the UK(specific locations would be amazing) with burrows in the banks I would be so so grateful.

Any information would be great,
Thank you!!
