Summary:

Amphibian survey conducted in 2010-2012 in two mid-field ponds in the village of Stare Czarnowo, in the north-western part of Poland. The aim of the study was to evaluate the species composition and abundance of adult and juvenile amphibians and their breeding sites. It was found that in both ponds dominated brown frogs: especially Rana arvalis and green frogs: Pelophylax esculentus, Pelophylax lessonae. We meet them not only during the mating season, but throughout the study period also in adjacent agricultural fields and coastline. Less numerous in this area occurred: Hyla arboreta and Bombina bombina. The rarest representative of batrachofauna was Pelobates fuscus, which appeared only in one pond in 2012. In both ponds were recorded occurrence of a representative of the tailed amphibians: Lissotriton vulgaris. Numerous occurrence of amphibians in these mid-field ponds is a good sign, because batrachofauna is an excellent bioindicator aquatic environment.
