Davies' tree frog

Davies' tree frog (Ranoidea daviesae) is a species of frog in the subfamily Pelodryadinae. It is endemic to Australia. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, subtropical or tropical dry shrubland, and rivers. It is currently threatened by habitat loss.

Description
Davies' tree frog is a medium-size species which grows to a maximum snout-to-vent length of 53 mm for males and 63 mm for females. The colour of the upper surface is somewhat variable, being mainly golden brown with darker brown patches but sometimes additionally having green patches. There is a narrow brown stripe running from the nostrils through the eye and back towards the groin, broadening towards the posterior and then becoming intermittent. Below the eye is a green band running as far as the shoulder and there is a thin white line along the edge of the upper lip. The skin on the underside has fine granulations. Davies' tree frog is very similar in appearance to the closely related New England tree frog but is larger, is less green and has a slightly bumpy rather than a smooth skin.

Distribution and habitat
Davies' tree frog is endemic to the eastern side of the Great Dividing Range in New South Wales, Australia. It has been found in a number of separate locations from north of the Hunter River to the Hastings River drainage, a distance of about 150 km. It is only known from altitudes greater than 400 m and is found near streams and rivers with well-vegetated banks. In deep gullies the surrounding area is wet sclerophyll forest and rainforest while in the tableland the streamside vegetation is mostly tea tree (Leptospermum sp.), ferns, and grass tussocks in areas of dry, open woodland or heathland.

Conservation status
Davies' tree frog has a very restricted range and an area of occurrence of less than 20000 km2. It is an uncommon frog and its habitat is threatened by forest clearance for agricultural purposes, and some of the streams in which the frog breeds have been stocked with exotic fish such as trout, carp and mosquitofish which may feed on the tadpoles. For these reasons, the IUCN has assessed this frog as being a "vulnerable species".
