20.500.12556/DiRROS-20789 Spremljanje pritalne vegetacije gozdov v Sloveniji kaže na zmanjševanje števila rastlinskih vrst Monitoring of the forest ground vegetation in Slovenia shows a decline in the number of plant species Spremljanje stanja in sprememb pritalne vegetacije gozdov v Sloveniji poteka v okviru mednarodnega programa ICP Forests na dveh različnih ravneh (raven 1 in 2). Na ravni 2, ki vključuje reprezentativne ploskve za intenzivni monitoring gozdov (ploskve IM), sistematično spremljamo stanje pritalne vegetacije že od leta 2004. Ob četrti ponovitvi popisa v letih 2019/2020 smo ugotovili, da se je v obdobju od prvega popisa število vrst v zeliščni plasti na večjih vegetacijskih podploskvah v povprečju zmanjšalo za –7,1 % in na manjših za –11,2 %. Čeprav se je na večini ploskev IM število vrst zmanjšalo (najizraziteje v nižinskih gozdovih), pa se je predvsem zaradi velikopovršinskih motenj na posameznih ploskvah vrstna pestrost tudi povečala. V prihodnje bomo v okviru spremljanja sprememb pritalne vegetacije gozdov namenili večjo pozornost tudi procesom termofilizacije, evtrofikacije in biotske homogenizacije, ki jih že zaznavamo v pritalni vegetaciji slovenskih gozdov. The monitoring of the state and changes in ground vegetation in Slovenian forests are conducted within the framework of the international ICP Forests programme at two distinct levels: Level 1 and Level 2. At Level 2, which encompasses representative intensive forest monitoring plots (IM plots), the status of ground vegetation has been subjected to systematic monitoring since 2004. The fourth repetition of the survey, conducted in 2019/2020, revealed a decline in species richness in the herb layer. On average, the number of species declined by –7.1% in the larger vegetation sub-plots and by –11.2% in the smaller ones. Although the number of species has decreased in the majority of IM plots (most notably in lowland forests), species diversity has also increased in some plots, primarily as a result of large-scale disturbances. In the future, in the context of monitoring changes in the ground vegetation of forests, we will also pay more attention to the processes of thermophilisation, eutrophication and biotic homogenisation, which are already observed in the ground vegetation of Slovenian forests. spremljanje pritalne vegetacije zeliščna plast številčnost rastlinskih vrst vrstna pestrost velikopovršinske motnje intenzivni monitoring ground vegetation monitoring herb layer plant species richness species diversity large-scale disturbances intensive monitoring true false true Slovenski jezik Angleški jezik Neznano 2024-11-07 14:36:09 2024-11-07 14:36:09 2025-08-01 13:30:19 0000-00-00 00:00:00 2024 0 0 str. 245-252 št. 6 Letn. 82 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-01-01 630*52:630*1 0017-2723 214001667 RAZ_Kutnar_Lado_2024.pdf RAZ_Kutnar_Lado_2024.pdf 1 5FCC4E78A0396157DF08FA3346E1CEEC 45c1e937abecc27049f06addbe254aa06fcf8ecdaac308d4338b17487200f209 4caecda2-9d0d-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=29343 Zveza gozdarskih društev Slovenije Gozdarski vestnik 0 0 0
