1029 Freshwater pearl mussel Margaritifera margaritifera
This tributary of the Afon Mawddach lies within a little-modified catchment and supports the only population of freshwater pearl mussel Margaritifera margaritifera in Wales that is regarded as viable. Recruitment is evident, with some juveniles recorded in recent years, although the population is comparatively small at an estimated 1500 individuals.
1831 Floating water-plantain Luronium natans
Floating water-plantain Luronium natans is not especially abundant or strongly flowering in the Afon Eden but it does represent a rare and significant survival, and this population, scattered along ~100 m of meander pools, is an exceptional instance of the species’ growth in naturally slow-flowing waters.
