Alders are among the rare and overlooked tree species and the most important of the ones growing in Slovenia is black alder (Alnus glutinosa) forming peculiar mire and riparian forests. In this article we comparatively present two monodominant black alder associations: Carici elongatae-Alnetum in fens and Stellario nemorum-Alnetum in groves; due to the poor knowledge of ecology,hydrology, ethnobotanics, symbolics, and infrequence we often unduly despise and recklessly destroy.

Med redkimi in prezrtimi drevesnimi vrstami so tudi jelše in med tremi, ki rastejo pri nas, je najpomembnejša črna jelša (Alnus glutinosa), ki gradi svoje vrstne močvirne in obvodne gozdove. V sestavku smo primerjalno predstavili dve monodominantni črnojelševi združbi: Carici elongatae-Alnetum na grezu in Stellario nemorum-Alnetum v logu, ki jih zaradi nepoznavanje ekologije, hidrologije, etnobotanike, simbolike in redkosti neupravičeno preziramo ter nepremišljeno uničujemo.
