Monitoring & Surveying – Arun & Rother Rivers Trust

Monitoring & Surveying

ARRT undertakes a range of river monitoring and surveys across the Arun & Western Streams catchment area, including assessing habitat and water quality, looking for invasive non-native species and identifying sources of pollution and erosion. So far we have conducted surveys of more than 50km of rivers and streams. We help run the Rother Riverfly scheme using citizen science volunteers too.

Together with the South Downs National Park Authority (SDNPA) we facilitate Riverfly monitoring of the Rother and in time plan to expand this across the ARRT catchment. This work complements a wider ARRT objective to engage and assist more volunteers to record/monitor the health of the river through ecological surveying. If you would like to get involved in protecting your local river and have a couple of hours a month to spare then you could become one of our Riverfly Monitors.

Monitors sample river invertebrates once a month (from spring to autumn) to help us keep an eye on water quality and river health as part of the national Anglers’ Riverfly Monitoring Initiative. Volunteers are required to attend a free Riverfly training day before starting their monitoring to learn how to sample and identify the river flies.

All monitoring equipment is kindly provided free by the SDNPA. To find out more please contact ARRT and complete a VOLUNTEER FORM. Further information about the Riverfly Monitoring Initiative can be found below.
