GNEZDITVENA GOSTOTA LESNE SOVE Strix aluco V URBANIH GOZDOVIH LJUBLJANE (OSREDNJA SLOVENIJA). (Slovenian)

Results of the survey carried out in the territories of Tawny Owl Strix aluco in Ljubljana urban forests (Tivoli, Rožnik and Šišenski hrib Nature Park and Golovec Hill) were compared with the species territory density in non-urban forest of Mt. Krim. Surveys were performed with the point count method using playback in the springs of 2002 and 2016. The density established at Golovec Hill was 9.3 territories / 10 km2, while in Tivoli, Rožnik and Šišenski hrib Nature Park it reached 10.4 territories / 10 km2, which was higher than at Mt. Krim (4.1-5.8 territories / 10 km2), although densities between sites were not statistically different. Based on our surveys, the estimated population size of the urban Tawny Owl in Ljubljana would consist of 57 to 65 pairs. Our results suggest that the Tawny Owl can adapt well to the living conditions in the city urban forests and indicate the importance of the forest patches in urban areas. [ABSTRACT FROM AUTHOR]

V prispevku podajamo rezultate popisov teritorijev lesne sove Strix aluco v urbanih gozdovih Ljubljane, Krajinskega parka Tivoli, Rožnik in Šišenski hrib ter Golovca, ki smo jih primerjali z gostoto v neurbanem gozdu na Krimu v bližini Ljubljane. Popisovali smo z uporabo metode izzivanja s posnetkom samčevega oglašanja spomladi 2002 in 2016. Na Golovcu smo ugotovili gostoto 9,3 teritorija / 10 km2, v Krajinskem parku Tivoli, Rožnik in Šišenski hrib pa 10,4 teritorija / 10 km2, kar je več kot na Krimu (4,1-5,8 teritorija / 10 km2), čeprav razlike med območji niso bile statistično značilne. Na podlagi dobljenih gostot ocenjujemo, da na območju Ljubljane gnezdi med 57 in 65 parov lesnih sov. Lesna sova je glede na gnezdenje v urbanih gozdovih dokaj prilagodljiva vrsta, rezultati naših popisov pa kažejo na pomembnost zaplat gozdov v urbaniziranem okolju. [ABSTRACT FROM AUTHOR]
