Growth and Development Dynamics of Young Holm Oak (Quercus Ilex L.) Stands after Shelterwood Cutting in Open Forest Road Conditions

چکیده
The Mediterranean forest region has been exposed to anthropogenic impacts for centuries, and the constant biotic abiotic factors, together with increasing climate change, have hindered proper management of ecosystems. This study presents results multiyear, systematic, specific practical monitoring conversion holm oak coppices using principles shelterwood system. It also growth development dynamics stand on a permanent experimental plot from 1997 2017. research was performed in Eumediterranean vegetation zone coniferous (Forest Management, Buzet branch, Pula Forestry Office, Magran Cuf unit, compartment 83a). all properties manna ash forests (Orno-Quercetum ilicis H-ić/1956/1958). basic elements structure were monitored: diameter at breast height (DBH), tree height, horizontal crown projection, ground shading (light) appearance abundance woody vegetation, special emphasis young generations seed. paper describes threats limiting growth, survival seed (strong shooting tendencies coppiced bay laurel trees, excessive presence shrubs). Forest requires effective, timely repeated tending thin stands (already under canopy), while protecting trees wild game. statistical method interpolation determined trends development; trend equation coefficient determination (R2) is very high. indicates direction renewal stands. Shelterwood cutting, regular through seven-year regeneration period, resulted high quality oak, first its kind broader area. indigenous as fundamental climatogenic species species, multiple roles such protection erosion, resilience factors fires, tourism landscape functions, other general therefore deserve intensive ongoing research. Holm play part conserving genetic biological diversity, potential persistence ecosystems, improving structure, stability ecosystems long-term increase commercial value Croatian Mediterranean.

Conservation of genetic diversity in artificially regenerated holm oak (Quercus ilex L.) populations
Reforestation with autochthonous species should take into account the preservation of the variability and the geographical structure of genetic diversity in forest species. In order to provide empirical data, genetic composition of an artificial population of holm oak (Quercus ilex L.) and its natural seed-origin population in Andalusia were analysed with six microsatellite loci. The genetic di...
متن کاملGrowth, Development and Yield in Pure and Mixed Forest Stands
Objective: Ecosystems with mixed species compared to the ones with pure compositions provide a broader range of options in the fields of biodiversity, conservation, protection and restoration. Nearly all forest plantations are established as monocultures, but research has shown that there are potential advantages to be gained by using carefully designed species mixtures in place of monocultures...
متن کاملDrought tolerance and transplanting performance of holm oak (Quercus ilex) seedlings after drought hardening in the nursery.
Drought stress is the main cause of mortality of holm oak (Quercus ilex L.) seedlings in forest plantations. We therefore assessed if drought hardening, applied in the nursery at the end of the growing season, enhanced the drought tolerance and transplanting performance of holm oak seedlings. Seedlings were subjected to three drought hardening intensities (low, moderate and severe) for 2.5 and ...
