20.500.12556/RUL-149784 Analiza mladja na Pahernikovi posesti Analysis of regeneration on Pahernik's property V diplomski nalogi smo preučili pomlajevanje na Pahernikovi posesti, s poudarkom na pojavu in razvoju mladja do prsnega premera 10 cm. Analizirali smo gostoto, razvojne faze, vpliv objedanja, zmes drevesnih vrst in vpliv temeljnice. Na 363 podploskvah smo popisali mladje na celotni posesti, ki se razprostira med 350 m in 1543 m nadmorske višine. Ugotovili smo precej nizko gostoto mladja na podploskvah A (276 osebkov/ha), B (994 osebkov/ha) in C (15.924 osebkov/ha), pri čemer se razlike med nadmorskimi višinami in prostorsko ločenimi deli posesti niso pokazale kot izrazite. V mladju je prevladovala smreka (38 %), sledili sta jelka (32 %) in bukev (26 %). Mladje je zastiralo 24 % površine tal, pritalna vegetacija pa 11 %. Rastlinojeda divjad je vplivala na nazadovanje jelke, še posebej v razredu do 1,3 m višine s stopnjevanjem po višinskih stopnjah, kar kaže na naraščajočo problematiko. Poprečno objedanje mladja do 1,3 m je znašalo 33 %, jelke pa 39 %. Gostota mladja se je zmanjševala z večjo velikostjo podploskev, saj se je tam popisovalo večja in starejša drevesca. Delež drevesnih vrst v pomladku se je v primerjavi s prejšnjo inventuro ugodno spremenil v smeri zmanjševanja deleža smreke. Analiza vpliva temeljnice ni pokazala statistično povezane gostote mladja in višine temeljnice. Sklepamo, da je bila izvedena nega mladja smiselna, saj je delež sproščenih ciljnih osebkov zadovoljiv. Kakovostne informacije o mladju so ključne za načrtovanje ukrepov, spremljanje stanja in trajnostno gospodarjenje z gozdovi. In the thesis, we studied regeneration on the Pahernik property, focusing on the occurrence and development of young trees up to 10 cm in diameter at breast height. We analysed density, developmental stages, effects of ungulate browsing, tree species mixture, and effects of basal area. Young trees were recorded in 363 subplots across the entire property, which ranges from 350 m to 1543 m above sea level. We found rather low tree regeneration densities in subplots A (276 individuals/ha), B (994 individuals/ha) and C (15,924 individuals/ha), with no marked differences between altitudes and spatially separated parts of the property. Norway spruce was the dominant species (38%), followed by silver fir (32%) and European beech (26%). Tree regeneration covered 24% of the soil surface and ground vegetation 11%. Herbivorous game has influenced the decline of the fir, especially in the height class up to 1.3 m, with a progression in height levels, indicating a growing problem of overbrowsing. The average browsing of regeneration up to 1.3 m was 33% and of silver fir 39%. The density of young trees decreased with increasing sub-plot size, as larger and older trees were inventoried there. The tree species mixture of the regeneration has changed favourably compared to the previous inventory, with a decreasing proportion of Norway spruce. We didn’t confirm correlation between the density of regeneration and the height of the basal area. We conclude that the tending of the regeneration was reasonable, as the proportion of released target trees is satisfactory. Good information on regeneration process is essential for action planning, monitoring and sustainable forest management.
