This paper provides phytosociological tables that describe scrub and forest communities with Alnus viridis in the Slovenian Alps. We described three new associations: Rhododendro hirsuti-Alnetum viridis (a green alder community on calcareous bedrock in the Eastern and Southeastern Alps), Huperzio selagi-Alnetum viridis (a green alder community in the silicate rocks under Mt. Komen in the eastern Savinja Alps) and Alno viridis- Sorbetum aucupariae (a successional stage of mountain ash and green alder on potential beech sites in the foothills of the southern Julian Alps; similar stages are known also elsewhere in the Alps), and presented additional three associations (Polysticho lonchitis-Fagetum, Rhodothamno-Laricetum and Rhododendro hirsuti-Pinetum mugo) whose stands comprise green alder. V članku s fitocenološkimi tabelami opisujemo grmiščne in gozdne združbe, v katerih v slovenskih Alpah uspeva vrsta Alnus viridis. Opisali smo tri nove asociacije: Rhododendro hirsuti-Alnetum viridis (združba zelene jelše na karbonatni podlagi v vzhodnih in jugovzhodnih Alpah), Huperzio selagi-Alnetum viridis (združba zelene jelše v silikatnem skalovju pod goro Komen v vzhodnih Savinjskih Alpah) ter Alno viridis-Sorbetum aucupariae (sukcesijski stadij jerebike in zelene jelše na potencialno bukovih rastiščih v prigorju južnih Julijskih Alp, podobne stadije poznajo tudi drugod v Alpah) ter predstavili še tri druge asociacije (Polysticho lonchitis-Fagetum, Rhodothamno-Laricetum in Rhododendro hirsuti-Pinetum mugo), v čigar sestojih uspeva zelena jelša.
