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 second of NRN's 2024 invertebrate surveys (see events list for the next dates).
