Polystichum aculeatum (L.) Roth, syn: Polystichum lobatum (Huds.) Chevall.Hard Shield-fern, DE: Gelappter SchildfarnSlo.: bodea podlesnicaDat.: Oct. 5. 2015Lat.: 46.37040 Long.: 13.73188Code: Bot_917/2015_DSC9210Habitat: riparian mixed forest, Salix eleagnos, Picea abies, Fagus sylvatica dominant trees; moderately steep mountain slope, northwest aspect; calcareous, ground; in shade, high air humidity; partly protected from direct rain by tree canopies; elevation 560 m (1.850 feet); average precipitations ~ 3.000 mm/year, average temperature 6-8 deg C, alpine phytogeographical region. Substratum: forest soil.Place: Lower Trenta valley, left bank of river Soa, between the Soa trail and the river, slightly downstream of Maselc farm house, East Julian Alps, Posoje, Slovenia EC.Comment: Polystichum aculeatum is mainly a montane fern and quite common in the Upper Soa river region. It grows in the whole Alpine belt and almost in all other European mountains. The plant is tolerant regarding nutrients and chemical properties of the soil. It only moderately prefers calcareous ground and humid environment. Its winter resistant, shiny leaves can be easily found during winter months. Characteristic trait are large and abundant brown scales on its stems, particularly at their baseRef.:(1) M.A. Fischer, W. Adler, K.
