Reintroduction of perennial knawel Scleranthus perennis along a conservation path at Santon Downham, Suffolk, England

  • Published source details Leonard Y. (2006) Reintroduction of perennial knawel Scleranthus perennis along a conservation path at Santon Downham, Suffolk, England. Conservation Evidence, 3, 11-12.


The endemic subspecies of perennial knawel Scleranthus perennis ssp. 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 'conservation path' in the county of Suffolk. Plants were introduced and seeds sown in what appeared suitable areas. Members of the public visiting the site have provide sufficient soil disturbance to ensure the ground is suitably bare for establishment of new seedlings with little additional management required except occasional removal of encroaching heather Calluna vulgaris. To date, the reintroduction has been successful.
