Resumen:
This standard provides guidance on methods for monitoring freshwater pearl mussel (Margaritifera margaritifera) populations, and the environmental characteristics important for maintaining populations in favourable condition. Throughout this document, use of the word Margaritifera refers only to the species Margaritifera margaritifera (Linnaeus, 1758). The standard is based on methods developed and used successfully by Margaritifera experts in Europe, and describes approaches that individual countries have adopted and found to be useful for survey, data analysis and condition assessment. The applications of the standard include reporting under the Habitats Directive (Article17: http://bd.eionet.europa.eu/article17/reference portal), undertaking environmental impact assessment, and restoring pearl mussel populations. While it is recommended that the causes for pearl mussel decline should be urgently investigated, standard methods for restoring populations are beyond the scope of this document.
