121. Značilnosti opravljanja sečnje in spravila v zasebnih gozdovih v SlovenijiŠpela Ščap, Darja Stare, Nike Krajnc, Matevž Triplat, 2021, original scientific article Abstract: V raziskavi, opravljeni leta 2019, je bilo zajetih 544 naključno izbranih gospodinjstev, ki imajo v lasti gozd. Več kot polovica anketi%ranih ima v lasti gozdno posest, veliko od 1 do 4,99 ha. Za 62 % anketiranih je glavni namen gospodarjenja z gozdom uporaba lesa za lastne potrebe. V obdobju 2015%2019 je sečnjo in spravilo opravljalo 71 % anketiranih, ki so v tem času skupaj posekali nekaj manj kot 50.000 m3 lesa (24 m3 /ha ali 141 m3 na gospodinjstvo). Intenziteta sečnje je bila najvišja pri zasebnih lastnikih z malimi gozdnimi posestmi (do 0,99 ha), in sicer v povprečju 41,4 m3 /ha. Analiza je pokazala, da obstajajo statistično značilne razlike med velikostjo gozdne posesti in intenziteto sečnje. V anketi je bilo ugotovljeno, da so za 41 % sečnje in spravila poskrbeli poklicni izvajalci del. Z raziskavo smo potrdili značilen vpliv velikosti zasebne gozdne posesti na način izvedbe sečnje in spravila. Rezultati so pokazali, da je največji delež zasebnih lastnikov, ki vsa dela opravijo s pomočjo najetih izvajalcev, v velikostnem razredu gozdne posesti od 5 do 9,99 ha. Z raziskavo nismo potrdili statistično značilnih razlik v intenziteti sečnje med spoloma zasebnih lastnikov gozdov

122. Private forest owner characteristics affect European spruce bark beetle management under an extreme weather event and host tree densityMaarten De Groot, Jurij Diaci, Kaja Kandare, Nike Krajnc, Rok Pisek, Špela Ščap, Darja Stare, Nikica Ogris, 2021, original scientific article Abstract: In the last few decades, an increasing number and intensity of bark beetle outbreaks have plagued the forests of Europe and North America. Bark beetle management is directly related to forest owner characteristics, although this relationship is not well understood. The purpose of the study was to investigate the influence of forest owner characteristics on the amount and timing of sanitary felling under different disturbance regimes and quantities of Norway spruce. We combined different databases on sanitary felling, the timing of sanitary felling, and forest owner characteristics for Slovenia from 2014 to 2018 and analyzed the amount and timing of sanitary felling in relation to forest owner characteristics. We found that the timing in winter and the amount of sanitary felling were positively associated with the distance of the owner%s residence to the forest parcel. Larger parcels were more affected by bark beetles but did not have later timing of cutting in the summer period as was hypothesized. The timing of sanitary felling decreased with property size, while with the probability of sanitary felling, the effect of property depended on the ice storm and the amount of spruce. The size of the settlement, the permanent address of the private owner, and timing of sanitary felling were positively associated but also depended on the amount of spruce. Gender and age did not have an important influence on the amount and timing of sanitary felling. Forest owners are an important factor in effective bark beetle management. This study highlights the private forest ownership characteristics that should be emphasized in order to fight bark beetle outbreaks in the event of large-scale disturbances. Governments should support forest owners who are at greater risk of bark beetle outbreaks and less efficient in managing outbreaks. Furthermore, landowner characteristics should be included when forecasting bark beetle outbreaks.
