Redd Spotting

Redds are the nests of wild brown trout, which are 'cut' between November and March.  Recording them allows us to see whether these important native fish are declining, and also if the entire river is healthy, since brown trout are only present in good water quality.  They are visible as distinct mounds of clear gravel, usually between 1 and 3 feet long. 



Approximately every two weeks, between November and March, ARK's trained redd surveyors walk their stretch of river and mark the location of each new redd on a map or recording sheet.  After the end of each redd season a report is written and all of the redds are plotted onto a map of the whole of the Upper Kennet.  This identifies the best stretches of river, and which areas may need restoration.



We hope to expand surveying downstream to gather data from a wider area of the Kennet - look out for details of further Redd spotting training opportunities on our events page or email Anna Forbes to express your interest.
