Pulau Ular has been proposed as a wildlife sanctuary by the Sabah Nature Society. It serves as a breeding site for three species of terns: Bridled Tern (Onychoprion anaethetus), Black-naped Tern (Sterna sumatrana), and Roseate Tern (Sterna dougallii). The island is also an important stopover site for migratory waterbirds between October and April.
Other important stopover sites for migratory waterbirds in Labuan include the Sungai Labu tidal flats, the Sungai Lada wetlands near SMK Rancha-Rancha, Labuan Botanical Garden, and the Nagalang and Kinabenuwa tidal flats.
The island lies just off the Tanjung Layang-Layangan Cross-bedding geosite, where Belait Formation strata extend across the tidal flat towards Pulau Ular at low tide.
