This species has only been recorded from sandsheet areas in the Howard River catchment and the Elizabeth River catchment, south of Darwin in the Northern Territory of Australia. It might occur more widely.
Habitat and Ecology
It has been found in open savannah/Grevillea woodland, on ephemerally flooded sands with short to medium-height grasses; sedges and herbs are dominant in the understory (Young et al., 2005). The main breeding areas are characterized by shallow pools with small mounds (possibly termite) with clumps of grass growing over the tops, sparse tea tree Leptospermum spp., and Banksia. Several species of carnivorous plants, such as sundews (Drosera spp.) and bladderworts (Utricularia spp.), are common within the habitat. Most male U. daviesae were observed calling from small chambers at the base of sand mounds within flooded grassland, either on wet sand or in very shallow water.
Populations of this species have been found throughout the Howard River catchment (Young et al., 2007), suggesting that it is common through its small known range.
There is no information on threats, though it occurs in an area of limited human impact.
The information available thus far suggests U. daviesae is restricted to the sand sheets of the Howard River and the Elizabeth River, and it has not been identified outside of these catchments (Young et al., 2005). Additional surveys across a broader range of northern Australia designed to target U. daviesae would be valuable to confirm twhether or not its distribution is genuinely restricted. It is not known from any protected areas.
