20.500.12556/DiRROS-30317 Sekundarna sukcesija v kisloljubnih gozdovih rdečega bora na Golovcu (Slovenija) v obdobju 1942–2024 Secondary succession in the acidophilous Scots pine forests on Golovec hill (Slovenia) in the period 1942–2024 Raziskava obravnava spremembe kisloljubnih gozdov rdečega bora na Golovcu v obdobju 1942–2024 na podlagi ponovitve fitocenoloških popisov prof. Gabrijela Tomažiča in dodatnih sodobnih popisov. Rezultati kažejo izrazit upad vrstne pestrosti, zlasti v zeliščni in grmovni plasti, ter umikanje rdečega bora, ki ga nadomeščajo bukev, graden, kostanj in smreka. Zastiranje mahov se je močno zmanjšalo, medtem ko sta orlova praprot in borovnica postali še dominantnejši. Fitoindikacija kaže na zmanjšano svetlobo v sestojih, več hranil in manjšo zakisanost tal kot posledico opustitve steljarjenja in kopičenja listnega opada. Analiza kaže, da poteka sekundarna sukcesija iz nekdanjih pionirskih borovih sestojev prek bolj ali manj dolgotrajnih stadijev mešanih gozdov gradna in domačega kostanja v smeri kisloljubnih bukovih gozdov, ki so se na ugodnejših rastiščih že uveljavili. Golovec tako danes zaznamujejo predvsem prehodni in različno napredovali sukcesijski stadiji mešanih gozdov. The study examines changes in acidophilous Scots pine forests on Golovec Hill between 1942 and 2024, based on repeated phytosociological surveys conducted by Prof. Gabrijel Tomažič and additional contemporary relevés. The results show a marked decline in species diversity, particularly in the herb and shrub layers, as well as a retreat of Scots pine, which is being replaced by beech, sessile oak, sweet chestnut, and Norway spruce. Moss cover has decreased sharply, while bracken and bilberry have become even more dominant. Phytoindication reveals reduced light availability in stands, increased nutrient levels, and lower soil acidity as a result of the abandonment of litter raking and the accumulation of deciduous leaf litter. The analysis indicates that secondary succession is progressing from former pioneer pine stands through more or less long-lasting stages of mixed oak–chestnut forests toward acidophilous beech forests, which have already established themselves on more favourable sites. Golovec is now characterized primarily by transitional and variably advanced successional stages of mixed forests. sekundarna sukcesija kisloljubni gozdovi vrstna pestrost fitocenologija rdeči bor Pinus sylvestris bukev Fagus sylvatica kostanj Castanea sativa Golovec secondary succession acidophilous forests species diversity phytosociology Scots pine Pinus sylvestris beech Fagus sylvatica sweet chestnut Castanea sativa Golovec true false true Slovenski jezik Angleški jezik Znanstveno delo 2026-06-19 12:37:53 2026-06-19 12:37:53 2026-06-20 03:51:45 0000-00-00 00:00:00 2026 0 0 str. 63-82 Vol. 139 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2026-06-19 630*18(497.4)”1942-2024”(045)=163.6 2335-3112 10.20315/ASetL.139.5 282258179 ASetL-139_5_2.pdf ASetL-139_5_2.pdf 1 8F75317053BC96CBF161C6E6E21383B7 3197e47cb5dc4009f06414e1a22c87563085069512bca11c4b5fe000607dcb38 3c1c9c32-6bba-11f1-be3d-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45975 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
