However, owing to the short-term nature of many previous studies, regeneration success of sessile oak could not be properly ascertained.<br \/>\n<strong>Aims<\/strong> This study examined oak seedling development over a time period of ten growing seasons in canopy openings of 0.05 to 0.2 ha in size created through group selection harvesting in a mature mixed sessile oak forest in southwestern Germany. We tried to answer the following research questions: (i) how do initial stand conditions relate to and interact with oak seedling density and seedling height growth, and (ii) what are the driving factors of regeneration success under the encountered site conditions.<br \/>\n<strong>Methods<\/strong> We evaluated the influence of solar radiation, <em>Rubus<\/em> spp. cover, initial oak seedling density, and competition from other tree species on change in density and height of oak seedlings, as well as overall regeneration success (oak seedlings \u2265 150 cm in height).<br \/>\n<strong>Results<\/strong> Regeneration success increased with initial oak seedling density and solar radiation levels and decreased with early <em>Rubus<\/em> spp. cover. Density and maximum height of oak seedlings was negatively related with competition of other woody species.<br \/>\n<strong>Conclusion<\/strong> Results of our longer-term study demonstrate that forest management activities to regenerate sessile oak naturally are only successful in stands (i) without advance regeneration of other woody species and without established, recalcitrant ground vegetation, (ii) with a sufficiently high initial oak seedling density in larger patches following mast years, and (iii) where periodic monitoring and control of competing woody individuals can be ensured. Our findings further corroborate the view that natural regeneration of sessile oak in small-scale canopy openings is possible in principle.<\/p>\n<p><strong>Keywords<\/strong><br \/>\nNatural regeneration, Forest gap, Canopy opening, Interspecific competition, <em>Rubus<\/em> spp., Seedling density, Close-to-nature forest management<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-020-00972-y'  style='float: right; ' ><\/div>\n<p><strong>Publication<\/strong><br \/>\nKuehne, C., Pyttel, P., Modrow, T. et al.
