Abstract: | Many methods for using diatoms for routine monitoring of water quality have been developed in Europe and, in some countries,
these are being used to enforce environmental legislation. In order to facilitate their wider use, particularly with respect
to European Union legislation, steps are being taken to harmonize methodology. In this paper, the principles and practice
of sampling are described in relation to the main habitat types encountered in Europe. Although details of methods and sampling
programmes have to be tailored to particular circumstances and the overall objectives of the monitoring, a number of generalizations
can be made. Where available, rocks and other hard surfaces are the preferred substrates and methods for sampling these are
described. If such substrata are not available, then introduced ('artificial') substrata have many applications. Various types
of introduced substrata can be used successfully, so long as some basic precautions are described. Other types of substrata
such as macrophytes and macroalgae may also be useful under certain circumstances, although there is less consensus in the
literature on the most appropriate methods, and of the validity of comparisons between indices computed from epiphytic and
epilithic communities. When designing surveys, it is recommended that as far as possible, extremes of non-water quality factors
(e.g. shade, current speed, etc) are avoided, unless these are characteristic of the system under investigation. Detailed
guidelines for sampling epilithon are described. Along with the recommendations for sampling other substrata, it is hoped
that these provide a framework that can be adapted to most river types in Europe.
