Združba se pojavlja na strmih do zelo strmih pobočjih, v gričevnatem in submontanskem pasu ter na toplih legah tudi v montanskem v submediteranskem delu Slovenije. Najdemo jo na nadmorskih višinah med 200 in 1200 m. Rastišča so dobro namočena, od 1300 do 1600 mm, srednja letna temperatura zraka je od 10 od 20° C. Na karbonatni podlagi se razvijejo rendzine različnih razvojnih stopenj. Diagnostična kombinacija rastlinskih vrst Združba črnega gabra in jesenske vilovine je sekundarna združba, ki se pojavlja predvsem na potencialnih rastiščih združbe puhastega hrasta in črnega gabra, najdemo pa jo tudi na potencialnih rastiščih združbe bukve in jesenske vilovine ter kraškega gabra in puhastega hrasta. Na strmih pobočjih poteka razvoj gozda relativno počasi. Združba črnega gabra in jesenske vilovine je nizki gozd ali grmišče. Višina črnega gabra sega od 3 do 10 m. Drevesna plast ponekod manjka in je v teh primerih dobro razvita grmovna plast. Zeliščna plast je večinoma bujna, medtem ko je mahovna pogosto slabo razvita. Gospodarska vrednost teh sestojev je majhna. Les je uporaben predvsem za kurjavo, saj so posamezna drevesa le redko uporabna za gradbeni les. Njihova glavna vloga pa je varovalna: varuje plitva kraška tla, zadržuje meteorno vodo, je prepreka vetrovom in omogoča progresivni razvoj gozda. Združbo črnega gabra in jesenske vilovine uvrščamo v zvezo Ostryo-Carpinion orientalis. |
The Seslerio autumnalis–Ostryetum occurs on steep to very steep slopes, in the colline-submontane belt and on warm sites, and in the montane belt as well. It is distributed in the submediterranean region of Slovenia. It grows at altitudes ranging from 200 to 1,200 meters. It grows well on wet sites with 1,300 to 1,600 mm of rainfall annually and an annual average temperature from 10o C to 20o C. The parent material is calcareous where rendzic Leptosols develops. Diagnostic combination of plant species The Seslerio–Ostryetum is a secondary association that occurs particularly on the potential sites of the Ostryo–Quercetum pubescens. It is also found on the potential sites of the Seslerio–Fagetum and Ostryo–Carpinetum orientalis. On steep slopes, the development of forests takes place relatively slowly. The communities of the Seslerio–Ostryetum are low forest or shrubbery. The height of Ostrya carpinifolia is three to ten meters high. The tree layer is missing in some places, and in these spots the shrub layer is well developed. The herb layer is usually lush while the moss layer is often poorly developed. The economic value of these stands is low. The wood is used for fuel, and individual trees are seldom used for construction timber. Their main role is protective since they protect the shallow karst soil, retain rainwater, create barriers against the wind, and ensure the progressive development of the forests. The Seslerio autumnalis–Ostryetum carpinifoliae is classified in the alliance Ostryo–Carpinion orientalis. |
