What geographic features and wildlife are found on Upolu?

Upolu is the most populous island of Samoa, characterized by a volcanic central mountain range that reaches its highest point at Mount Fito (3,608 feet). The island features a densely forested interior, fertile coastal soils, and a wet tropical climate. A significant portion of the south-central region is protected within O Le Pupu-Pu'e National Park, which was established in 1978.12

The island's wildlife is relatively limited but includes a variety of tropical birds and native mammals. Specifically, the endangered flying fox and other smaller bat species are the only native mammals found on the island. The broader Samoan environment, which includes Upolu, supports over 50 species of birds—including the rare tooth-billed pigeon—as well as various lizards, snakes from the boa family, and a wide range of insects, spiders, and centipedes.12
