Abstract
In spring of 2020 we observed leaf phenology in mature European beech (Fagus sylvatica) trees in Tivoli, Rožnik and Šišenski hrib Landscape Park in Ljubljana, Slovenia (46.05°N, 14.49°E, 310 m a.s.l.). A group of 11 trees was selected for daily monitoring of leaf development. We recorded seven phases from dormant buds, through leaf unfolding till development of mature leaves. At thesame time,photos were taken to illustrate the leaf development. First developing leaves were observed on 4 April in one tree. General leaf unfolding, as defined by International Phenological Gardens (IPG),was in different trees observed between 7 and 25 April 2020. Occurrence and duration of individualphases of leaf developmentshowed great variation within and between trees. General leaf unfolding of the tree included in long-term monitoring program of the Environmental Agency of the Republic of Slovenia (ARSO) occurred on DOY 105(14April 2020) which is 4days earlier then long-term averageof the same tree whichis ascribed to above average temperatures in winter of 2019/2020.

Title:Fenologija razvoja listov navadne bukve (Fagus sylvatica) na rastišču v Ljubljani v letu 2020
Abstract:
V Krajinskem parku Tivoli,Rožnik in Šišenski hrib v Ljubljani (46,05°S, 14,49°V, 310 m n. m.) smo spomladi leta 2020 opazovali fenologijo razvoja listov odraslih dreves navadne bukve (Fagus sylvatica). Izbrali smo skupino enajstih dreves za dnevno opazovanje,beleženje in fotografiranje razvoja listov. Razlikovali smo sedem faz od mirujočih brstov, preko različnih faz olistanja do zrelih listov. Prve razvijajoče se liste smo na enem drevesu opazili 4. aprila 2020. Fazo splošnega olistanja, kot jo določa metodologija Mednarodnih fenoloških vrtov,smo pri različnih drevesih beležili od 7. do 25. aprila 2020. Pri nastopu in trajanju različnih faz razvoja listov smo zabeležili velike razlike znotraj posameznega drevesa in med drevesi. Splošno olistanje pri drevesu, ki ga dolgotrajno opazuje Agencija RS za okolje (ARSO),je nastopilo na zaporedni dan 105(14. aprila 2020), kar je 4 dni prej kot kaže dolgoletno povprečje za isto drevo. Slednje pripisujemo nadpovprečno visokim temperaturam v zimi 2019/2020.
