River Meon Catchment Invertebrate Fingerprinting Study
Wessex Chalkstreams and Rivers Trust collected invertebrate samples from 12 sites on the River Meon in both the Spring and Autumn of 2017. The Association paid for the analysis of the samples, with the results compared to historical Environment Agency data. The Study showed that the Meon was subject to a range of ecological pressures but evidence of these pressures was less pronounced than on the Test and Itchen. Invertebrates at the sample sites were predominantly Unimpacted or Slightly Impacted by the four key stressors: sediment, phosphate, organic pollution and pesticides. Freshwater shrimp (Gammarus) counts at the sample sites were typically above 1,000, double the recently agreed target of 500 for a healthy chalkstream.
