Ecology and status of Erica vagans in County Fermanagh, Ireland
1974
NELSON, E.C. | COKER, P.D.
The colony of Erica vagans in County Fermanagh, Northern Ireland was surveyed and soil and species-association analyses were carried out. The species is found in a base-rich flush, were it survives due to reduced competition from calcifuge species and is associated with other species that tolerate the relatively calcareous environment. The colony is uniquely uniform in flower colour and does not appear to be able to reproduce sexually at this time. The species probably arrived in Ireland in postglacial times and has since becomegeneticallydistinct.fi. vagans does not appear to be a recent introduction, though man may have been involved in determining its present distribution and that of the other so-called “Hiberno-Lusitanian”Ericaceae. While considerable doubt remains concerning the origin and age of the colony, the species cannot be regarded as native.
