The Hornwort and Liverwort Atlas of Romania

Signs used:Bolded names – species included in the Bern Convention and in the Law 13/1993;Underlined names – species included in Annex II of the Habitats Directive 92/43/EEC;* - Identified as new species for Romania in the last 10 years.Species protected by legislationThe main legal mechanisms for the protection of bryophyte species in Romania are the Law13/1993 by which Romania joins the Bern Convention on the Conservation of European Wildlife andNatural Habitats, OU 236/2000, OU 57/2007 and OM 1964/2008, which includes two liverworts andeight mosses from Romania: Frullania parvistipula, Mannia triandra, Buxbaumia viridis, Dichelymacapillaceum, Dicranum viride, Encalypta mutica, Hamatocaulis vernicosus, Meesia longiseta,Orthotrichum rogeri, and Pyramidula tetragona.THE RED LIST OF HORNWORTS AND LIVERWORTS TO ROMANIAFollowing the field studies and the examination of scientific literature during over 10 years ofscientific activity, a large amount of chorological data was gathered, that was used in the assessment ofthe degree at which Romanian liverworts are endangered, according to Hallingbäck & al. (1998) and theIUCN 2001 - version 3.1. criteria, adapted for Romania.In the assessment of the degree at which Romanian hornworts and liverworts are endangered,several factors were taken into account, namely:a. the distribution of the species,b. the degree of occupation in the distribution area,c. fragmentation of the distribution area,d. number of localities,e. the degree of degradation of the occupied habitats by:i. desiccation,ii. land clearing,iii. pollution,iv. other anthropic modifications,f. the dependence of habitats with reduced distribution (bogs).g. conservation status in EuropeFollowing this evaluation two hornwort species (2 CR – critically endangered) and 69 liverwortspecies (35 CR – critically endangered, 20 EN – endangered, 14 VU – vulnerable) were identified asthreatened.1.
