In the December 1997 issue of British Wildlife (9:110), E E Green reported on the successful use of the hemi-parasitic Yellow Rattle, Rhinanthus minor, to suppress dominant grasses in a herb-rich meadow site in Berkshire. The generality of these results is confirmed by experiments carried out in an alluvial flood meadow at North Duffield Ings, North Yorkshire, and further sites in northern Italy, by Debbie Davies and colleagues from York (Biological Conservation 82:87-92).
