NatureScot Research Report 1141 - Freshwater pearl mussel survey of a river in the Trossachs
Freshwater pearl mussels were noted in the past few years in areas where they were not previously recorded and activities in the river could be damaging them. Scotland has an important population of these rare mussels, but they are very sensitive creatures to water quality, wildlife crime and physical crushing. We commissioned several surveys and produced a series of management recommendations because we found large numbers of freshwater pearl mussels all along the river and in places we would not have expected to find them. We hope to conduct further surveys in local rivers and use this information to change the way we manage the land around them in order to protect the freshwater pearl mussels.
