Whilst volunteer monitoring has many benefits for both volunteers and professionals, volunteer data must be validated to understand the value and potential applications of information from volunteer monitoring programmes. Our study aimed to assess the concordance between volunteer and professional data, including state and trend assessments. We compared macroinvertebrate data collected by volunteers using a simplified identifi...

Microbiological contamination arising from faecal pollution is a widespread effect of human activity on aquatic systems, with management of the issue complicated because contamination sources are often unknown. Recent advances in molecular techniques have permitted the use of host‐specific genetic markers to apportion sources of faecal pollution. In this study, we used a tiered approach employing faecal indicator bacteria and...
