Geographic Range [top]
Range Description: This species is widespread in Southeast Asia. It ranges from southern Thailand into Peninsular Malaysia (including Pulau Tioman) and Singapore, from here south into Indonesia as far as Bali (including the Mentawai Archipelago, Sumatra, Nias, the Riau Archipelago and Java), Borneo (Brunei, Kalimantan, Sabah and Sarawak), and the Philippines (Basilan, Culion, Dinagat, Leyte, Luzon, Mindanao, Palawan, Polillo, Sibutu, Panay, Samar and the Sulu Archipelago). Records from the Lesser Sundas east of Bali, including Sambawa and Flores, refer to the recently-described B. hoeseli. B. cynodon is found from close to sea level to around 600 m asl. in the Philippines. The presence of this snake in Myanmar is uncertain.

Habitat and Ecology [top]
Habitat and Ecology: This highly arboreal, oviparous species is found in a wide range of habitats, from primary and secondary forest, to cultivated areas, rural gardens and urban areas (Steubing and Inger 1999). It is often found in coconut plantations (D. Iskandar pers. comm. October 2011). In forested areas, it is known to live in the canopy (D. Iskandar pers. comm. October 2011). It feeds on small vertebrates. In Bali, Indonesia, the snake is fairly common in secondary forest and gardens, particularly where it is able to inhabit trees and bushes over rivers and streams (R.P.H. Lilley pers. obs. 2011). The presence of young animals in these areas indicates that the species probably breeds successfully in secondary habitats, although alternatively snakes may be seeking refuge in the small areas of relatively undisturbed riverine habitats which remain at the edges of cultivated land (R.P.H. Lilley pers. comm. October 2011).
Systems: Terrestrial
Use and Trade [top]
Use and Trade: This species is found in small numbers in the pet trade, but no data is available. It is not a heavily traded species.
Threats [top]
Major Threat(s): Although forests are under pressure throughout its range, there are no major threats to this widespread and adaptable species.
Conservation Actions [top]
Conservation Actions: This snake has been recorded from many protected areas. Further research is needed into the taxonomy, distribution and natural history of this species. Although this species is not in need of specific conservation actions, protection of additional forests within its range, and efforts to limit deforestation, are recommended as general conservation measures across Southeast Asia, and will benefit this species.
