Diatom populations of five microhabitats of a poor (Sphagnum) fen in Bijambare Protected Landscape area were studied. The fen is situated at an altitude 930 m a.s.l., on a slope of Mt. Zvijezda near Sarajevo. The major part of the fen is covered with Sphagnum recurvum and Sphagnum subsecundum, while at the outer borders communities are dominated by Carex spp. Samples were taken in May, July and October 2007 and May 2008, in vegetationally different microhabitats by squeezing water from mosses and taking material from pools. The diatom flora was studied under LM and SEM. The part of the fen that is characterized by Sphagnum species has a very poor diatom assemblage dominated by acidobiontic and acidophilous species such as Eunotia exigua, E. glacialis, E. paludosa and Pinnularia rhombarea. In the border area of the fen, diatom assemblages become richer with Nitzschia acidoclinata, Eolimna minima and Eunotia bilunaris as dominating species. According to published data, 45 taxa are recorded here for the first time for Bosnia and Herzegovina such as: Chamaepinnularia mediocris, Navicula digitulus, Navicula medioconvexa and Placoneis hambergii. Sellaphora bosniaca and Sellaphora hafnerae are described here as a new species.
