River Dee Special Area of Conservation (SAC) Comparative Macrophyte Surveys (2008)

The Countryside Council for Wales (CCW) commissioned ECUS Ltd. to undertake macrophyte survey work on the River Dee Special Area of Conservation (SAC) to inform a larger project aiming to determine the main variability components for macrophyte communities in rivers. The objective of the larger project, a partnership between CCW, Natural England, the Environment Agency (EA), Scottish Environmental Protection Agency (SEPA) and Scotland and Northern Ireland Forum For Environmental Research (SNIFFER), is to develop and test a statistically robust, standardised field sampling method for river macrophytes, to be used by the agencies for assessment of ecological and conservation status of rivers.

Lineage: There are a variety of macrophyte survey methods currently used within the UK, which have been developed over the years for differing purposes and therefore have different emphasises built into their design. One standard method, developed by the NCC for classification of vegetation communities of British Rivers, was updated to become the JNCC Standard Common Standards Monitoring (CSM) methodology and is currently used to by the UK conservation agencies to determine the condition status of Riverine SSSI (Site of Special Scientific Interest) and SACs (Special Area of Conservation). The CSM methodology is based on the survey of 500 m stretches, recording macrophyte species present using a 3 point cover score. It was originally designed primarily as a means of surveying river reaches in order to record the maximum number of species present. Another commonly used survey method is the Mean Trophic Rank (MTR) methodology, developed by the Environment Agency to assess the impact of sewage treatment works on the trophic status of the rivers into which they discharge, as required by the EC Urban Waste Water Treatment Directive. The survey methodology, which uses a 100 m survey section and records macrophyte species using a 9 point cover scale, has been adopted in a slightly modified version as the new LEAFPACS methodology developed by the Environmental Protection Agencies (EA and SEPA) for the purposes of monitoring ecological status of rivers as required by the EU Water Framework Directive (WFD).
