20.500.12556/DiRROS-21116 Analiza mladja na Pahernikovi posesti Analysis of regeneration on Pahernik's property Kakovostno naravno pomlajevanje je ključno za sonaravno gospodarjenje, a ker gozdna inventura ne zagotavlja dovolj informacij, smo v letu 2023 izpeljali dodatno vzorčenje mladovja na mreži stalnih vzorčnih ploskev na Pahernikovi posesti. Ugotovili smo sprejemljive povprečne gostote mladja pod 130 cm višine s 15.924 osebki ha-1, mejno zadovoljive gostote mladovja nad 130 cm višine in s premerom < 5 cm z 994 osebki ha-1 in nizke gostote za mladovja med 5 in 10 cm premera z 276 osebki ha-1. Vse mladovje je v poprečju zastiralo 24 % površine tal, pritalna vegetacija pa 11 %. Razlike v gostotah in zastiranju mladovja med nadmorskimi višinami in prostorsko ločenimi deli posesti niso bile izrazite. V mladovju je prevladovala smreka (38 %), sledili sta jelka (32 %) in bukev (26 %). Visok delež jelke je bil na račun visokih gostot v višinskem razredu do 20 cm. V višjih razredih je bilo jelke vse manj, objedenost po rastlinojedi divjadi je bila intenzivnejša. Povprečno objedanje mladja do 1,3 m je znašalo 33 %, jelke pa 39 %. Izpeljana inventarizacija in analiza mladovja nakazujeta možnosti izboljševanja gozdne inventure. High-quality natural regeneration is the key to close-to-nature management, but forest inventories often fail to provide sufficient information. In 2023, we conducted additional sampling of regeneration in a network of permanent sampling plots on the Pahernik property. We found acceptable average densities for seedlings below 130 cm height, with 15,924 individuals ha-1, less satisfactory densities for saplings above 130 cm height and < 5 cm diameter, with 994 individuals ha-1, and low densities for saplings between 5 and 10 cm diameter, with 276 individuals ha-1. On average, regeneration covered 24% of the forest floor, while ground vegetation covered 11%. There were no major differences in regeneration density and cover between elevations and spatially separated parts of the property. The regeneration was dominated by Norway spruce (38%), followed by silver fir (32%) and beech (26%). The high proportion of silver fir was due to its high densities in the height class up to 20 cm. In the higher classes, silver fir was less represented and increasingly browsed by ungulates. The average browsing rate of regeneration up to 1.3 m was 33%, and specifically for silver fir, 39%. This study indicates possibilities for improving the forest inventory. gostota in zmes drevesnih vrst veliki rastlinojedi parkljarji poškodbe mladovja smrekovo-jelovo-bukovi gozdovi jelovja gozdna inventura density and mixture of tree species large herbivorous ungulates regeneration damage spruce-fir-beech forests fir forests forest inventory true false true Slovenski jezik Angleški jezik Neznano 2024-12-30 11:15:51 2024-12-30 11:15:52 2025-01-27 03:34:23 0000-00-00 00:00:00 2024 0 0 str. 39-51 Vol. 135 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-01-01 630*52:630*23:630*45:630*92(497.4Pahernikova posest)=163.6 2335-3112 10.20315/ASetL.135.4 220666371 RAZ_Rihter_Tomaz_2024.pdf RAZ_Rihter_Tomaz_2024.pdf 1 1BA327D1AE4F594F112F7683561087ED 0e64ca8a891335b5e9fec450479ee417f48bc363495eae6d1f9cbc5dda7019a2 075244e2-dbdc-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=30311 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
