Near Threatened Taylor's Bug-Eyed Frog

Scientific Name Theloderma stellatum

Photo Taken At Fresno Chaffee Zoo, Fresno, California

IUCN Red List Status Least Concern

Population

The size of this species' population is not well known, however it has been detected in a number of surveys (e.g. Taylor 1962, Wassersug et al. 1981, Stuart and Emmett 2006, Poyarkov et al. 2015). It is likely that ongoing forest loss associated with expanding agriculture throughout Southeast Asia (Sodhi et al. 2009) is causing some population declines. There are captive populations under this species' name in Europe and North America (T. Ziegler and J. Holden pers. comm. March 2012), however, it is possible that some of these are actually Theloderma vietnamense. Further surveys are needed to determine its population ... Read More

Threats

Habitat loss and degradation due to rapidly expanding agriculture is an ongoing threat to biodiversity throughout Southeast Asia (Sodhi et al. 2009). High rates of deforestation for logging, and agricultural encroachment on forest are ongoing in much of Thailand and Cambodia (Sodhi et al. 2009). Other causes of habitat loss in Cambodia are the illegal removal of certain tree species for the harvest and refinement of safrole oil, as well as increasing human settlement, both of which are ongoing within protected areas (Ohler et al. 2002, Bradfield and Daltry 2009). This species is very likely threatened to some degree by ... Read More

Geographic Range

This species is currently known from west of the Mekong River in western and central Thailand and south-western to central Cambodia (Taylor 1962, Wassersug et al. 1981, Stuart and Emmett 2006, Poyarkov et al. 2015). These may not represent the actual limits of the species' range as similar habitat to that in the species' known localities extends into a small section of adjacent Peninsular Myanmar. Further surveys there may uncover its presence, and they have been included in the range map associated with this assessment. The species' estimated extent of occurrence (EOO) is 361,602 km2, which represents four threat-defined locations. ... Read More

Habitat

This species is associated with lowland and seasonally flooded to montane evergreen forest and has mostly been observed on the trunks of trees (Taylor 1962, Wassersug et al. 1981, Inger et al. 1999, Stuart and Emmett 2006, Stuart et al. 2006, Luu et al. 2014). Eggs and larvae of the species have been observed during September in Thailand (Wasserburg 1981). This species is a phytotelm breeder; it attaches its eggs to the trunk of a tree directly above a water-filled hole, inside of which the larvae develop (Taylor 1962, Wassersug 1981). Habitat throughout much of this species' range is undergoing ... Read More
