Riverfly

Riverfly Monitoring Initiative survey data for sites in the UK and Ireland contains total scores and individual group scores for each survey date. Data are collected by trained volunteers to a nationally recognised standard and compared to a trigger level. If scores fall below that trigger level, this is reported to the environmental regulator for investigation. Volunteers upload their survey data to the Cartographer platform and records are verified by local coordinators. Verified data is automatically pulled into this ArcGIS Online feature layer daily.

Along with other freshwater invertebrates, they are a vital part of the freshwater ecosystem and food chain. RMI focuses on three key groups: • Mayflies (Ephemeroptera) • Caddisflies / Sedges (Trichoptera) • Stoneflies (Plecoptera) Their limited mobility, long life cycles, year-round presence, and sensitivity to environmental changes make them excellent indicators of water quality, pollution, siltation, and low flows.
