Statement of Use
This report sets out procedural guidance on how to carry out Mean Trophic Rank (MTR)
macrophyte surveys to assess the trophic status of rivers, and on the use of the method for the
purposes of the EC Urban Waste Water Treatment Directive. The methodology can also be used
for other applications. The guidance supersedes and replaces earlier, internal guidance issued to
Environment Agency staff. It is intended as 'best practice' standard methodology for all MTR
surveys and is applicable throughout the UK.
