Abstract:
In conjunction with the hydrological and water quality monitoring, a monitoring regime was designed to detect how freshwater ecology responds to changes in agricultural diffuse pollutants. The data gathered have been used to confirm the WFD ecological status of the study sub-catchments, to explore spatial and temporal variability in biological quality elements, and to identify those pollutants that are most likely to be causing failure to achieve Good ecological status. This background data provides an evidence base to both inform, and assess the impact of, mitigation measures. Macrophytes were surveyed in each subcatchment and WFD tools have been used to establish the status of this Biological Quality Element (BQE). The biological monitoring sites are closely matched to the hydrological and water quality monitoring stations, which will allow observed change in the BQE to be linked to reductions in diffuse pollution and on-farm diffuse pollution mitigation measures. The macrophyte monitoring data being made available here consists of the list of plant taxa found (with an areal cover estimate) and associated environmental data in each surveyed reach at the 11 Avon & Tamar DTC sites.

Data Quality Statement:
The macrophyte community was surveyed in line with UK Water Framework Directive protocols, as set out by the UK Water Framework Directive Technical Advisory Group.
Protocol: The River Macrophyte Biological Standard Method uses the principle that different macrophytes are associated with different amounts of nutrients (especially phosphorus); with different combinations, quantity and numbers of macrophytes are expected to be present depending on the river type and its fertility.
