The distribution of butterfly species (Papilionoidea) using the transect method was studied the area of mountain Srednji vrh (1853 m) in the western Kamnikean Alps. During eight sampling sessions conducted between May and August 2024, we confirmed the presence of 51 butterfly species across 14 transects, with additional 3 species observed only outside the transects. We compared butterfly species diversity in relation to habitat type, elevation, exposition, and the average density of flowering plants per square meter. Our findings indicate that the area is mostly inhabited by generalist species, as well a few higher altitude species and one protected species. Among habitat types, the highest diversity of butterfly species was observed along forest paths, while significantly fewer species were recorded in intensive meadows. Differences in species diversity between north- and south-facing transects were not statistically significant. Differences in the amount of flowering plants are more noticeable in butterfly abundance than in butterfly species, with positive correlations observed in both cases, though these correlations were not statistically significant. Species diversity peaked at mid-elevations and declined with increased altitude. Extensive meadows supported high number of butterfly species, highlighting the importance of implementing conservation measures to protect them.
