20.500.12556/RUL-114124 Conversion of Pinus nigra plantations with natural regeneration in the Slovenian Karst the importance of intermediate, gradually formed canopy gaps Since the mid-19th century, Pinus nigra plantations have played a key role in the restoration of degraded European landscapes. Nowadays, these plantations are aging and prone to natural disturbances, insect infestations, and diseases. For their successful gradual conversion, knowledge of optimal gap spatiotemporal dynamics is crucial. We studied herb and natural regeneration patterns along with site factors on 477 subplots within 44 plots distributed over four stand types: closed stand (14% diffuse light), open stand (21%), gap edge (23%), and gap (57%). Despite the abundant Quercus petraea, Q. cerris, and Q. pubescens mast year, no one-year seedlings were recorded, which is likely due to the summer drought. Short seedlings (h < 20 cm) of Quercus sp., Fraxinus ornus and Ostrya carpinifolia were more successful within closed stands. Short Quercus seedlings were positively associated with soil depth and negatively associated with soil nutrients, distance to seed trees, and Sesleria autumnalis coverage. Taller Quercus seedlings required more light than both of its strongest competitors and were positively related to humid soils and less rocky sites. Ungulate overbrowsing significantly impeded natural regeneration. The results indicate a satisfactory Quercus density for conversion and the importance of advanced regeneration, which should be gradually, but persistently, released by progressively widening gaps. gap partitioning microsite partitioning topsoil moisture microrelief ground vegetation overbrowsing conversion Pinus nigra natural regeneration velikost vrzeli mikrorastišča vlaga tal talna vegetacija objedanje rastlinojede divjadi gozdovi true false true Angleški jezik Slovenski jezik Članek v reviji 2020-02-18 11:02:31 2020-02-18 11:02:32 2022-08-26 03:49:15 0000-00-00 00:00:00 2019 0 0 13 str. iss. 12, art. 1136 Vol. 10 2019 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 630*22 1999-4907 10.3390/f10121136 5605030 3872166 RAZ_Diaci_Jurij_2019.pdf RAZ_Diaci_Jurij_2019.pdf 1 5A7969F8D858FF8C7B2EFA201614420F 54252da6ec193d0c707b05e302e13fd7b6640a7b0b22af9ee1118e9d31f2c7f1 6902703f-4b6e-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151281 https://www.mdpi.com/1999-4907/10/12/1136 0 63de962e-4b6e-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151280 Biotehniška fakulteta 0 0 0
