Picea omorika is an endangered conifer endemic to Serbia and Bosnia-Herzegovina. This research reports the first case of its naturalisation in Italy, specifically in a restricted area of the upper Brembana Valley (Orobic Alps, Lombardy), where an uneven-aged population, of approximately 50–60 individuals, grows within a wood pasture at 1,760–1,790 m a.s.l., inside the Orobie Bergamasche Regional Park. Dendrochronological analysis indicates that this population likely originated from a single tree planted for ornamental purposes near a mountain hut in the 1960s. Over the past 30 years, the species has propagated in the study area under cold, suboceanic climatic conditions and on moderately moist, nutrient-poor, slightly acidic soils, as inferred from climatic data and Ellenberg ecological indicator values. Grime’s competitor, stress tolerator, ruderal (CSR) functional strategy analysis classified P. omorika as a strictly stress-tolerant species (C = 0.0%, S = 100.0%, R = 0.0%) with low invasive potential. Phytosociological analysis indicates that the P. omorika community is part of a secondary succession that is progressing from pastures of Nardion strictae towards high-montane coniferous forests of Piceion excelsae . This research contributes to a better definition of the ecological niche of P. omorika .
