Summary

The endemic subspecies of perennial knawel Scleranthus perennis prostratus is found only in the Breckland area of eastern England. Due to marked recent declines, an attempt was made to reintroduce it to a former site in the county of Suffolk. Eighty seedlings were planted in a ploughed plot and well-watered in. Some plants were initially scuffed out by rabbits Oryctolagus cuniculus, but steadily numbers increased over the subsequent two years to 240 plants. However, over the next three years numbers fell to only six individuals. It is thought that too much grazing and digging up of the plants by rabbits occurred in these latter years.
