The Moor frog very much resembles the pervasive European common frog. Distinguishing features include the males' bubbling call and their bluish colour at mating time.
Moor frogs populate various types of habitat featuring high ground water levels, e.g. swamp forest, wet meadows, silted-up sectors of larger water bodies and raised bogs. For reproduction purposes, they generally frequent shallow waters that warm up quickly. These water bodies, however, must hold enough water to warrant sufficient time for the tadpoles to develop completely.
The main threat faced by these frogs is the loss of habitat due to the drainage of bogs and wet meadows. Reaping machines also result in high losses during the mowing of wet meadows; extensive grazing, thus, is extremely beneficial for the moor frog. Hence, conservation measures must concentrate on creating shallow water bodies, securing - or restoring - higher ground water levels and a sensible use of terrestrial habitats.
