Nearly all plants and animals indigenous to Fiji are found on Taveuni, which has suffered less devastation from land clearance than other areas of Fiji. The absence of the mongoose, a major predator, has also played a part in the survival on Taveuni of land crabs, the unique Fiji fruit bat, the Taveuni silk bat, and some unique species of palm. The island is the second largest in the Pacific Ocean to be free from the mongoose. Other species found on the island include the Fiji banded iguana and both Platymantis vitiensis and P. vitianus frog species. The critically endangered Fijian monkey-faced bat is found only on Taveuni. It was discovered by scientists in 1977. The flowering plant Balaka seemannii, which is endemic to Fiji, is found on the island.

Taveuni is located at the northern end of the Koro Sea, and is entirely the product of volcanic activity. Fiji's third largest island is separated from Vanua Levu by the Somosomo Strait. The island is between 10 and 14 kilometres (6 and 9 miles) wide and 42 km (26 mi) long, is the top of a dormant, elongated shield volcano which erupted from a northeast-southwest trending rift on the ocean floor. About 150 volcanic cones dot the island, including Uluigalau, Fiji's second highest peak at 1,241 metres (4,072 feet), and Des Vœux Peak, next in height at 1,195 metres (3,921 feet). There have been at least 58 volcanic eruptions since the first human settlement around 950-750 BC, all of which affected the southern two-thirds of the island. Major eruptions from 300–500 AD caused abandonment of the southern areas until about 1100 AD. The latest eruption produced a lava flow at the southern tip of the island around 1550. The island's central ridge delineates the greatest volcanic activity surrounding volcanic vents.
