Summary

Dredging the silt from two old ponds in southern England (one in which the nationally endangered starfruit Damasonium alisma had recently been rediscovered) resulted in dramatic initial results, with many starfruit plants appearing. A subsequent rapid fall off in numbers suggests that seeds appear to germinate best on exposed sediment on drying margins and continuous low-level disturbance management is probably desirable.
