Scientific Name:	Boiga ranawanei
Species Authority:	Samarawickrama, Samarawickrama, Wijesena & Orlov, 2005

Assessment Information [top]

Red List Category & Criteria:	Data Deficient ver 3.1
Year Published:	2007
Assessor/s:	Samarawickrama, P.
Reviewer/s:	Cox, N. and Stuart, S.N. (Global Reptile Assessment Coordinating Team)
Justification: Listed as Data Deficient since it has only recently been described, and there is still very little information on its extent of occurrence, status, threats and ecological requirements.

Geographic Range [top]

Range Description:	This recently described snake is believed to range widely in Sri Lanka, although it is currently known only from Gannoruwa Forest and Morankanda in Kandy District, Central Province (Samarawickrama et al. 2005, P. Samarawickrama pers. comm.). In the area of the Gannoruwa Forest, specimens have been collected close to Bulawatha and Warathanna villages (Samarawickrama et al. 2005). The species has been recorded at elevations of 520 to 640 m asl.

Population [top]

Population:	Very few specimens are known, and presumably the species is naturally rare.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Animals have been collected in patches of natural forest, coffee plantations and home gardens (Samarawickrama et al. 2005, P. Samarawickrama pers. comm.).
Systems:	Terrestrial

Threats [top]

Major Threat(s):	The species is considered to be threatened by habitat disturbance resulting from the seasonal pruning of coffee plantations. It also is reported to be threatened by pesticide contamination within home gardens, and from purposefully set fires (P. Samarawickrama pers. comm.). It appears that as with many snakes, animals are generally killed when they are encountered.

Conservation Actions [top]

Conservation Actions:	The species has not been recorded from any protected area. Further research is needed into the species ecological requirements, its behaviour and the threats. There is a need to initiate awareness programmes for school students and communities about this species. Protection of areas of suitable habitat are needed, as is restoration of degraded areas (P. Samarawickrama pers. comm.).
