Assessing anuran biodiversity in Baranja region (Croatia) using local volunteers trained in amphibian audio monitoring and road kill determination

We aimed to compare success in assessing frog diversity using trained volunteers, with the data from specimens conserved in Croatian Natural History Museum, and the data gathered for BSc thesis. Total of 20 transects, 5km and 10 sampling stops each, were examined audio-visually by 17 volunteers from March 2006 to September 2007. Each transect was examined trice. Volunteers used were the ones with best exam results in the group of 35 attending 12h of lectures and 6h of workshops. For the purpose of this data analysis, one fi nding is defi ned as recorded presence of the species on one sampling stop, regardless of the actual number of individuals encountered. Total of 10 species were noted. There were 353 fi ndings recorded in 11 visited 10km UTM squares. The most diverse were CR26, CR27 and CR36. The most widespread species was Hyla arborea, while Bufo bufo, Pelobates fuscus, Rana temporaria were the least prevalent. Considering the fact that only 3 species are archived in CNH Museum, sampled in 1 UTM square, and only 7 species covering 2 UTM-s are recorded in the BSc thesis, the volunteers gained recent data useful for nature conservation planning, with minimal funds in a short period of time.
