What do the Bugs in our Brooks tell us about our Water Quality?

Following NRN’s 2 year water survey of 10 sites around Eynsham, local expert Dr. Maarten van Hardenbroek will help us survey the ponds and streams for invertebrates and help us understand  what they tell us about how clean our water is.

Will we find, for example, the extremely rare and beautiful crystal moss animal (Lophopus crystallinus, a rare freshwater bryozoan, pictured above), which was recorded in Eynsham’s Chil Brook in the 1970s and only exists in a few other sites in the UK? 

This workshop marks the start of NRN's quarterly invertebrate surveys (see events calendar for the next dates) 

We are very grateful to Oxfordshire County Council for supporting this event with their contribution to the cost of equipment.
