Summary:

The work describes the research on the settlement of the benthic macro invertebrates within different morphological conditions of the mountain stream channel. Along the paper the community structure of benthos was investigated within the point bars area of the Jałowiecki stream in the Makowski Beskid Mountains. To describe the habitat structure, influenced by varied granulometric and hydrologic conditions the research points of the different habitats types of benthic invertebrate were selected. Type 1; located on the top of riffles, type 2; located close To the proximal part of the bar, type 3; located on the opposite river bank within the area of the point bars and type 4; located in the shadow of mega clusters.
