Taxonomy [top]

Kingdom	Phylum	Class	Order	Family
Animalia	Chordata	Mammalia	Chiroptera	Pteropodidae

Scientific Name:

Pteropus lylei K. Andersen, 1908

Common Name(s):

English	–	Lyle's Flying Fox
Spanish	–	Zorro Volador De Lyle

Assessment Information [top]

Red List Category & Criteria:	Vulnerable A4cd ver 3.1
Year Published:	2008
Date Assessed:	2008-06-30
Assessor(s):	Bumrungsri, S., Suyanto, A. & Francis, C.
Reviewer(s):	Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority), Chanson, J. & Chiozza, F. (Global Mammal Assessment Team)
Justification: Listed as Vulnerable as it is estimated that a decline of over 30% has occurred in a fifteen year time period (three generations) including the past and the present, and this decline is expected to continue due to increasing trade and hunting pressure and ongoing decline in the extent and quality of its habitat.

Habitat and Ecology [top]

Habitat and Ecology:	Nothing is known from China about the ecology of this species (Smith et al. 2008). In other areas, it is known to form large colonies in trees that can become stripped of leaves by the bats' activity. It feeds in orchards and is regarded as a serious pest in Thailand (S. Bumrungsri pers. comm.). It occurs in mangrove forest in Viet Nam (Son Nguyen Truong pers. comm.). This species travels up to 50 km between colonies (S. Bumrugsri pers. comm.).
Systems:	Terrestrial

Threats [top]

Major Threat(s):	In Thailand the species is threatened through loss of roosting habitat, as existing trees die and are not replaced, it is also subject to hunting (S. Bumrungsri pers. comm.). It is also threatened in Cambodia by hunting (P. Bates pers. comm.).
