Abstract
Namen magistrskega dela je bil preučiti uspešnost sanacije in značilnosti obnove vetrolomnih površin. V raziskavo so bile vključene vetrolomne površine na Črnivcu in Bohorju, nastale v poletnih neurjih leta 2008. Postavili smo enaindvajset vzorčnih ploskev (10 m x 10 m) na naravno obnovljene površine in prav toliko na umetno obnovljene površine, ki so bile večinoma posajene z gorskim javorjem (Acer pseudoplatanus L.). V letih 2012 in 2014 smo izpeljali analize značilnosti sadik umetne obnove in dominantnih dreves naravne obnove. Izveden je bil tudi popis gostote in zastiranja naravnega mladja ter zastiranja zelišč in grmovnic. Zabeležili smo 17 različnih drevesnih vrst. Gostota naravnega mladja na naravno obnovljenih površinah je znašala 29.524 osebkov/ha in 7.460 osebkov/ha pri umetni obnovi. Gostota mladja se je med meritvama v povprečju povečala za 555 osebkov/ha na leto pri umetni obnovi in za 1746 osebkov/ha pri naravni obnovi. Klimaksnih drevesnih vrst je bilo glede na gostoto na naravno obnovljenih površinah 74 % in 31 % pri umetni obnovi. Zelišča in grmovnice so povprečno zastirale 99 % površine in so negativno vplivala na gostoto mladja. Od leta 2012 do 2014 je propadlo 15,9 % sadik in 9,6 % dominantnih dreves. Večjo verjetnost preživetja so imela drevesa, ki so v preteklosti imela večji premer koreninskega vratu in bolj sproščeno krošnjo. Sadike so bile v povprečju višje kot dominantna drevesa. Relativni višinski prirastki dominantnih dreves so bili večji kot pri sadikah. Šok po presaditvi je pri sadikah izzvenel po treh letih.

Title:Development of planted and natural regeneration on windthrow areas of Črnivec and Bohor
Abstract:
The purpose of the masters theise was to examine the effectiveness of the rehabiliton and remediation charasteristics windthrow area. The study includeed wind breakage surface on Črnivc and Bohor incurred during summer storms in 2008. We have twentyone sample plots (10 m x 10 m) on natural resurfacing and just as much an artificial resurfacing, wich were mostl planted with sycamore maple (Acer pseudoplantanus L.). In 2012 and 2014 we analyzed the chararateristics of seedlings and dominant trees. It was carried out a census of density and coverage natural seedlings and coverage herbs and shrubs. We recorded seventeen (17) different tree spices. The density of natural seedlings in natural renovated areas was 29.524 specimens per ha and 7.460 specimens per ha in the artificial reconstructions. The density of seedlings during measurements an average increase of 555 specimens / ha per year, in the natural regeneration. Climax tree spices in view of the density of the naturally reconstructed areas was 74 % and 31 % or artificial reconstruction. Herbs and shrubs were obscured on average 99% surface and have negative impact on densityof seedlings. From 2012 to 2014 it collapsed 15,9 % seedlings and 9,6 % dominant trees. Greater likehood of survival had trees, wich in the past had a larger root collar diameter and more relaxed crown. Seedlings were on average higher than the dominant trees. The relative height incerements dominant trees were larger that seedlings. Shock post- transplant seedlings resolved after three years.
