East Rennell Island is located at the southernmost tip of the Solomon Islands in the western Pacific Ocean. It is the third island south of Rennell Island, which is 86 kilometers long and 15 kilometers wide, making it the largest atoll in the world formed by coral accumulation. The main feature of this island is Lake Tegano, which used to be a lagoon of the atoll.

There are three main types of vegetation on Rennell Island: low juvenile forests on the peripheral karst ridges, tall forests inland, and vegetation along the shore of Lake Tegano, with pockets of mangroves. Most of Rennell Island is covered by dense forests with an average height of 20 meters. Despite the harsh natural environment with frequent cyclones, it remains a true natural laboratory for scientific research. There are 11 species of bats here, including the Rennell flying fox, as well as fruit-eating fish owls, Pacific flying foxes, and horseshoe bats.

Approximately 43 species of terrestrial and aquatic birds can be found here, with 4 species and 9 subspecies unique to Rennell Island, and 7 subspecies unique to both Rennell and Bellona Islands. Cormorants are common visitors to Lake Tegano. The pink-spotted fruit dove is a local species on Rennell and Bellona Islands, along with other local species like Rennell fantails and shrike-billbirds.
