Ground-ivy (Glechoma hederacea L., Lamiaceae) habitats in NE Slovenia

Ground-ivy ( Glechoma hederacea L.) is a widespread stoloniferous plant that grows in several ecologically diverse habitats: the open, at forest edge, and understorey. The vegetation of ground-ivy habitats was studied NE Slovenia terms floristic richness diversity, biological spectrum, phytogeography syntaxonomy. We identified five clusters distinct with occurrence ground-ivy, differentiated according to environmental conditions flora composition: eutrophic edges, trampled habitats, forests, which are divided into two groups different soil moisture, meadows. were assessed using Ellenberg indicator values, thus confirming ecological differentiation habitats. coexists 169 species from 49 families. highest Shannon diversity found meadows (100 species), while lowest (12 species). Plant coexisting belong 10 geoelements circumboreal, sub-cosmopolitan, Euro-Caucasian Eurasian represented all most life form hemicryptohytes up 88 % per relevé. syntaxon Molino-Arrhenatheretea dominates meadows, shrub edges Rhamno-Prunetea , Querco-Fagatea predominates forests. Ruderal Stellarietea mediae occurred except understorey where light limiting factor. A non-negligible proportion belongs Galio-Urticetea community characteristic an optimal habitat for ground-ivy.
