Vegetation of acidophilic pine forest

V diplomski nalogi smo želeli ugotoviti spremembe vrstne sestave gozdov na popisnih ploskvah združbe Vaccinio myrtilli-Pinetum sylvestris po prenehanju s steljarjenjem zadnjih osemdeset let v Sloveniji in sukcesijski razvoj kisloljubnega rdečeborovja v prihodnosti. Ponovili smo trideset popisov po botaniku Gabrijelu Tomažiču, na katerih smo ocenili vegetacijo v drevesni, grmovni, zeliščni in mahovni plasti po srednjeevropski fitocenološki metodi. Primerjali smo vrstno sestavo na nivoju popisnih ploskev, na način da smo ugotovili prisotnost novih in ohranjenih vrst leta 2020 ter delež vrst, ki so izginile od leta 1942 do danes. Primerjali smo tudi delež listavcev in rdečega bora ter prisotnost kisloljubnih vrst leta 1942 in 2020. Na ravni asociacije smo naredili sintezo s primerjavo stalnosti vrst po plasteh in števila vrst po plasteh na popisnih ploskvah. Za število vrst smo preverili razlike po plasteh s t-testom. Analizirali smo tudi stalnost vrst v plasteh po ploskvah. Dokazali smo sukcesijski razvoj združbe Vaccinio myrtilli-Pinetum sylvestris v smer razvoja listavcev.In the diploma thesis we wanted to determine changes in the species composition of forests on the vegetation plots of the association Vaccinio myrtilli-Pinetum sylvestris after the cessation of littering in the last eighty years in Slovenia and the successive development of acididophylic Scots pine forests in the future. We repeated thirty relevés according to the botanist Gabrijel Tomažič, on which we assessed the vegetation in the tree, shrub, herb and moss layers according to the Central-European phytocoenological method. We compared the species composition at the level of relevés by determining the presence of new and preserved species in 2020 and the share of species disappearing after 1942. We also compared the share of deciduous species and Scots pine and the presence of acidophylic species in 1942 and 2020. At the level of association, we made a synthesis by comparing the constancy of species by layers and the number of species by layers on relevés. For the number of species, we checked the differences by layers with the t-test. We also analysed the constancy of species in layers by plot. We have proved the successive development of Vaccinio myrtilli-Pinetum sylvestris in the direction of deciduous forest development
