Biological Monitoring

Sampling Freshwater Invertebrates

For over 25 years, OART has been undertaking biological monitoring on the waterways of the catchment. Using freshwater invertebrates as a means to understanding river health is an important part of our monitoring programme. From understanding site specific conditions to assessing long term population trends this monitoring shows us where problems are occurring along with showing whether projects are meeting their aims and objectives.

Led by our freshwater invertebrate expert we have a team of volunteers who collect and sort samples which are analysed and photographed using our digital microscopes. Scores are calculated to indicate water quality and invertebrate diversity providing a clear indication of the health of the river.

We also train communities in monitoring methods and identification skills to enable people to keep an eye on their own area whilst adding to our database.

We are always looking for support to carry on our water testing so visit our Get Involved pages to see how you can help.
