(2012): Invasion of central-European habitats by the moss Campylopus introflexus. – Preslia 84: 863–886. Although invasions by vascular plants are frequently studied, little is known about invasive bryophytes. Campylopus introflexus is an invasive moss endangering natural vegetation in western Europe and currently extending its secondary area eastwards. Therefore, we studied its ecology in the Czech Republic (central Europe). We updated its distribution, described colonized habitats in term of the composition of the vegetation, investigated substrate and water demands and which hab- itats in the Czech Republic are potentially at risk of invasion by C. introflexus. The first dataset con- tained 78 vegetation plots with C. introflexus from across the whole of the area investigated and included all the habitats colonized. The second dataset contained results of previous studies of the vegetation of pine forests both with and without C. introflexus and was used to determine the fine scale features of its habitat preferences within this habitat.
