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 inventoryKakovostno 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 %.
