Abstract: Juniperus communis L. is increasingly threatened in many parts of Europe, including the Baltic region. Our present study was aimed at evaluation of genetic diversity of J. communis populations of Lithu - ania. Fourteen selected populations differed in geography and habitats (coastal brown dunes covered with natural Scots pine forests, further referred as B; J. communis shrubs, F; transition mires and quaking bogs, D; subcontinental moss Scots pine forests, G; xero-thermophile fringes, E). Molecular variance was ana - lyzed among populations (140 individuals, in total), employing 14 Inter Simple Sequence Repeat (ISSR) markers. Percentage of polymorphic loci differed between populations belonging to the different habitat type, being the highest for population representing habitat F (68.2%) and the lowest for populations D (42.9%). The data demonstrate the possibility to underestimate or overestimate this parameter if some habitat populations are bypassed. Means per population of Nei‘s gene diversity and Shannon‘s informa - tion indexes, were 0.158 and 0.239, respectively. Significant correlation between genetic and geographic distance of populations of J. communis was documented by Mantel test. Bayesian analysis of ISSR data has separated populations of Southern Lithuania from Northern part. Juniperus communis populations represent - ing different habitats showed moderate interpopulation variance at ISSR loci. In ISSR-based dendrograms, individuals were correctly allocated to populations, even in case of populations growing in 0.5 km vicinity (habitats D and G). Among all populations the most distinct one was representing habitat of J. communis shrubs (F) protected by EUNIS
