20.500.12556/RUL-100774 Optimizing silviculture in mixed uneven-aged forests to increase the recruitment of browse-sensitive tree species without intervening in ungulate population An increase in ungulate abundance in Europe in recent decades has raised concerns for the survival of browse-sensitive tree species in its early life history stages. A possible strategy for mitigating the browsing-induced mortality of natural regeneration is to optimize silviculture. We used matrix population models parameterized for three types of Abies alba - Picea abies - Fagus sylvatica forests (3,183 permanent sample plots from three study areas in Slovenia, 39,717 ha), and a non-linear optimization to: (i) schedule optimal timing and intensity of logging in the next 100 years to increase the recruitment of Abies alba without intervening in the population of ungulates; and (ii) examine the influence of different natural recruitment rates on the potential for mitigating recruitment failure through silviculture optimization. The optimal management has required species-, growth- and diameter-specific logging, including intensive logging of large-diameter Abies alba in the first decades and strict conservation of recruits. The potential for mitigating recruitment failure through optimization increased progressively with natural recruitment rate and progressively at a decreasing rate with time. Optimizing silviculture was effective for maintaining Abies alba in stands exposed to low or moderate browsing pressures. Faced with chronic ungulate herbivory, forest managers should primarily focus on the reduction of herbivory and to a lesser extent on optimizing silviculture. continuous cover forestry optimization natural regeneration recruitment Abies alba raznomerni gozdovi optimizacija naravna obnova gozda novačenje Abies alba true false false Angleški jezik Slovenski jezik Delo ni kategorizirano 2018-04-13 11:33:39 2018-04-13 11:40:03 2022-08-14 03:41:54 0000-00-00 00:00:00 0 0 0 Str. 227-236 Vol. 11 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*23:630*91 1971-7458 10.3832/ifor2567-011 5045158 2513830 iForest_ifor2567-011_Ficko.pdf iForest_ifor2567-011_Ficko.pdf 1 1E86FFF78567570A1214E1EA3427CB1B 9a67261eb6be279eff5a526487cd1653d4ee07a24cfbf7ba5797f829384c38d9 1b77d5a2-a1b5-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=110570 Biotehniška fakulteta 0 0 0
