Lyle's flying fox may be threatened when the trees die, if they have not been replaced by new plantings. Another threat the bats face is hunting in Thailand and Cambodia and persecution by farmers across their range trying to protect their orchards. The International Union for Conservation of Nature estimates that populations have declined by more than 30% within the last fifteen years and has rated the conservation status of this flying fox as "vulnerable". Lyle's flying fox Lyle's flying fox ("Pteropus lylei") is a species of flying fox in the family Pteropodidae. It is found in Cambodia, Thailand and Vietnam, with an
Australian flying fox die-offs flying fox ("Pteropus poliocephalus") and the black flying fox ("P. alecto"). Where mixed-species colonies are affected the black flying fox suffers substantially higher mortality than the grey-headed flying fox. However, summer temperatures are more extreme within the range of the grey-headed flying fox than within the range of the black flying-fox, and therefore the actual total number of casualties is much higher among grey-headed flying foxes than black flying foxes. Mortality is especially high among dependent young and lactating females, but any demographic category can be affected. Observations in flying fox colonies during extreme heat events have revealed that flying
