The local extinction of most of the island’s native bird and lizard species was caused by the brown tree snake being accidentally introduced to guam. The decline of native plants and animals was caused by the removal of native pollinators.
The snake was first discovered on Guam in the 1950s, but it wasn’t until the 1970s that it was officially recognized as an invasive species in Guam, according to the U.S. Fish and Wildlife Service (USFWS). It is also found in Indonesia, Malaysia, the Philippines, Thailand, Vietnam, Laos, Cambodia, Myanmar, and Thailand’s southernmost province of Phnom Penh.
