Pelophylax lessonae

The Pool Frog (Pelophylax lessonae) is a European frog. It is one of only four amphibian species recognized by the UK government as protected under its Biodiversity Action Plan. The reasons for declining populations are decreased pond habitat from human encroachment and also air pollution leading to over-nitrification of pond waters. Its specific name was chosen by the Italian herpetologist Lorenzo Camerano in order to honour his master Michele Lessona.
