Gulliver, R, Gulliver, M, Sydes, C., and Long, D. 2007 The use of exclosures to produce a favourable grazing regime for the United Kingdom biodiversity action plan (BAP) orchid, Spiranthes romanzoffiana, on Colonsay, Inner Hebrides, Scotland. Book: High value grassland: providing biodiversity, a clean environment AND premium products. Proceedings of the BGS/BES/BSAS Conference No (access $32) In 1997 and 1999 two populations of Irish lady’s tresses orchid (Spiranthes romanzoffiana) (KA & KB) were detected at the back of an extensive, heavily grazed, dune system being managed under an Environmentally Sensitive Area agreement. Detailed monitoring of the populations was started in 1999. Initially there was no grazing at the site for 2.5 months in summer; but in August 2000 the regime was changed to continuous grazing by sheep and cattle. Two large exclosures around the orchid populations were established in 2001 to provide a four-month summer grazing break. Numbers in bloom varied greatly from year to year. The height of the first vegetation layer at the position of the flowering plants of S. romanzoffiana increased significantly between 2002 and 2005 and competition from other species may become a threat to the orchid. Therefore the length of the grazing break was reduced in 2006 at site KA and will be reduced in 2007 at site KB. Several aspects of the biology of the species remain to be investigated; especially the interaction with grazing animals, including the role of below-ground grazing, the detailed relationship of orchid distribution and abundance to sward structure, and the factors affecting sexual reproduction. The study provides an important example of the implementation of management decisions based on scientific monitoring.

Our discoveries about species distributed outside North America offer important evidence for repeated long-distance dispersal, often coupled with subsequent speciation-an uncommon phenomenon in Orchidaceae.
