Abstract

Diplomska naloga obravnava stanje dobovih gozdov v gozdnogospodarski enoti Ravensko. Poleg geografske razširjenosti in ogroženosti hrastov (Quercus spp.)v Sloveniji, je bil predmet raziskave diplomske naloge dob (Quercus rubor L.). Zaradi rezultatov že objavljenih raziskav obsežnega propadanja hrastov, je jedro naloge določanje dejavnikov, ki vplivajo na vitalnost doba. V diplomski nalogi so obravnavani in predstavljeni biotski dejavniki. Raziskovalni del naloge vsebuje analizo nabranih plodov doba in določanje poškodb, ki jih pozročil hrastov semenar (Curculio glandium Marsham) in (Andricus queruscalicis Burgdorf). Sledila je ocena poškodovanosti drevja v vegetacijski sezoni v letih 2006, 2007 in 2008 na lokacijah Hraščica in Ivanjci. Priročnik za ugotavljanje povzročiteljev poškodb (delovna različica) je bil izhodišče pri oceni zdravja sestojev. Ugotavljanje vitalnosti drevesnih vrst je možno po navodilih Priročnika le na trajnih raziskovalnih ploskvah ter skozi daljša časovna obdobja. Rezultati naše raziskave so pokazali na povečano prisotnost defoliatorjev v hrastovih sestojih ter poškodbzaradi hrastove pepelovke (Erysiphe alphitoides Griffon & Maubl.) v letu 2007.

Secondary title:	Health condition of lowland penduculate oak (Quercus robur L.) forests in forest - economy unit Ravensko
Secondary abstract:	The diploma deals with the condition of oak forests in the forestry unit Ravensko. The geographic distribution and endangerment of oaks (Quercus spp.) in Slovenia were stated. Our special interest was in the English oak (Quercus rubor L.). Researches of the extensive oak decay have already been made. Basedon the results of those researches, decision was taken to determine the factors that affect the vitality of oak. In the diploma the biotic factors were presented. The experimental part of diploma contains analysis of collected oak acorns and present damage by (Curculio glandium Marsham) and (Andricus queruscalicis Burgdorf). Tree damage in the vegetation season of the year 2006, 2007 and 2008 at the location of Hrašica and Ivanjci was evaluated. In the description of the forest health, Manual for the Assessment of Damage Sources (work version) was used. The assessment of tree species vitality is possible only in the accordance with the instructions of the Manual for the continual research on the permanent research plots and in longer periods. The results of our research indicated the increased presence of defoliators and the damages caused by oak powdery mildew (Erysiphe alphitoides Griffon & Maubl.) in the year 2007.
