Summary

The endemic subspecies of perennial knawel Scleranthus perennis ssp. prostratus is found only in the Breckland area of eastern England. Here it was restricted to north Suffolk, having been extirpated from all know Norfolk sites. In the mid 1990s an attempt was made to reintroduce it to one of its old Norfolk sites. Through a combination of transplanting locally cultivated plants, seed sowing, grazing, and occasional soil disturbance management. By 2005 perennial knawel had become well established and the introduction appears to have been very successful.
