H. Karst. in Central Europe is at risk under climate change scenarios, particularly in mountain regions. Little is known about the impact of environmental factors on the natural regeneration of P. abies in low-elevation mountain forests.<br \/>\n<strong>Aims<\/strong> We aimed to assess impacts of distance from the riverbank, soil pH, and light availability on natural <em>P. abies<\/em> regeneration. We hypothesized that (1) natural <em>P. abies<\/em> regeneration would depend on light availability and soil pH and (2) there are understory plant species which may indicate the microsites suitable for natural regeneration of P. abies.<br \/>\n<strong>Methods<\/strong> The study was conducted in the Sto\u0142owe Mountains National Park (SW Poland, 600\u2013800 m a.s.l.). We established 160 study plots (25 m2) for natural regeneration, light availability, soil pH, and understory vegetation assessment.<br \/>\n<strong>Results<\/strong> The highest densities of natural regeneration of <em>P. abies<\/em> were observed in sites with moderate light availability (0.1\u20130.2 of open sky) and low pH (3.5\u20134.5), and located relatively far from the riverbank. Cover of 22 understory plant species were correlated with natural P. abies regeneration densities, mostly positively.<br \/>\n<strong>Conclusion<\/strong> Different stages of natural regeneration of <em>P. abies<\/em> revealed different regeneration niches. Most understory plant species (bryophytes and herbs typical of coniferous forests) do not compete with natural regeneration of <em>P. abies<\/em>.<\/p>\n<p><strong>Keywords<\/strong><br \/>\nRecruitment, Understory vegetation, Diffuse non-interceptance, Soil pH, Seedlings, Saplings<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-018-0775-x'  style='float: right; ' ><\/div>\n<p><strong>Open Access Publication<\/strong><br \/>\nDyderski, M.K., Gazda, A., Hachu\u0142ka, M. et al.
