Abstract

(1) The largest population of Himantoglossum hircinum L in the U K. is found on a links golf course near Sandwich in Kent (2) Site suitability at the present time can be recognized by the possession of a suitable macroclimate in the local 40 km square, coupled with the presence of a suitable soil in the local 1 km square (3) The site of the golf course was identified on the HORIZON GIS using the Institute of Terrestrial Ecology's Land cover map. (4) A 40 km square which will become suitable in the future if the climate changes following a 5% increase in soil moisture deficit was chosen (5) The 1 km squares containing suitable soils within the chosen 40 km square were identified using the GIS (6) An area with the same land cover characteristics as those of the Sandwich population of H. hircinum was identified using the same GIS. This area, another links golf course, is considered to be a site which could sustain a population of H. hircinum in the future.
