20.500.12556/DiRROS-21426 Pregled odmiranja hrastov (Quercus spp.) v Evropi in pri nas Namen raziskave je bil s pregledom domače in tuje literature določiti najpomembnejše abiotske in biotske dejavnike odmiranja doba (Quercus robur) in gradna (Q. petraea) v Evropi ter pri nas in jim določiti nivo v Manionovi spirali propadanja. Pregledu literature je sledila analiza podatkov Zavoda za gozdove Slovenije o poseku gradna in doba v obdobju 1995–2022 na območju Slovenije. Po pregledu literature smo ugotovili, da na odmiranje gradna in doba vpliva kompleks abiotskih in biotskih škodljivih dejavnikov. Kot poglavitni dejavnik predispozicije in hkrati tudi sprožilni dejavnik se najpogosteje omenja sušni stres, katerega vpliv postaja s spreminjanjem podnebja vedno večji, od biotskih dejavnikov pa predvsem različne vrste gliv in fitoftor ter vnos najrazličnejših tujerodnih vrst. V proučevanem obdobju sta varstveno-sanacijski posek in posek oslabelega drevja pri dobu znašala kar približno 35 % skupne količine poseka oz. približno 204.000 m 3 , pri gradnu pa približno 27 % oz. približno 1.109.000 m 3 . Prevladujoči vzrok za varstveno-sanacijski posek in posek oslabelih dreves doba so bile bolezni oz. glive, za graden pa je bil to žled. The aim of this study was to determine the most important abiotic and biotic factors that contribute to the decline of sessile (Quercus robur) and pedunculate oak (Q. petraea) in Europe and in Slovenia and to determine their role in Manion‘s decline disease spiral by reviewing the scientific literature. To further determine the situation of sessile and pedunculate oak in Slovenia we analysed the data from Slovenian Forest Service regarding the felling of both oaks in the period from 1995 to 2022. After the literature review, we concluded that the decline phenomena of sessile and pedunculate oak are caused by a complex of biotic and abiotic factors. As the main predisposing and, at the same time, inciting factor in sessile and pedunculate oak decline, the literature mentions drought, that is being enhanced with the changing climate. From biotic factors, different species of fungi, phytopthora, and introduced invasive species are mentioned. The sanitation felling of sessile oak in the analysed period accounted for approximately 35 % (204,000 m 3 ) of all felling of sessile oak, and the sanitation felling of pedunculate oak accounted for approximately 27 % (1,109,000 m 3 ) of all felling of pedunculate oak. Fungal diseases were predominant reason for sanitation felling of sessile oak and sleet for sanitation felling of pedunculate oak. odmiranje hrastov hrast dob graden sanitarni posek oak decline sessile oak pedunculate oak sanitation felling true false true Slovenski jezik Angleški jezik Neznano 2025-02-01 22:21:32 2025-02-01 22:21:33 2025-02-02 03:37:39 0000-00-00 00:00:00 2024 0 0 str. 391-409 št. 10 Letn. 82 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-01-01 630 0017-2723 224787971 RAZ_Puhek_Aljaz_2024.pdf RAZ_Puhek_Aljaz_2024.pdf 1 7B06AD522A7957F887AC4BB06C732C3A 46f8dc8311031d18652e45fe172030dee14e9f4e91fec4f4b8c2dcaf17c55abc 923c7150-e0e2-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=30551 Zveza gozdarskih društev Slovenije Gozdarski vestnik 0 0 0
