Nepenthes sibuyanensis, a pitcher plant species, is also endemic as its scientific name suggests. There are 131 species of birds and ten species of fruit bats, and many dwelling mammals, reptiles, and rodents yet to be fully catalogued. Three birds subspecies are endemic to Sibuyan: the Philippine hanging parrot (Loriculus philippensis bournsi), the Philippine Pygmy-woodpecker (Dendrocopos maculatus menagei), and the Orange-bellied Flowerpecker (Dicaeum trigonostigma sibuyanicum), all of which were recorded there in the early 1990s. Five species of threatened mammals, one fruit bat and four rodents, are endemic to Sibuyan, and the endangered fruit bat Nyctimene rabori occurs there. An unspoiled ecosystem Sibuyan Island has been said to be one of the most unspoiled ecosystems in the Philippines and the world. The water of the Cantingas River as well as most of the other smaller rivers and rivulets on the island was tested to be one of the best water quality for human consumption worldwide. The drinking water of Sibuyanons come direct and untreated from rivers, springs and holes drilled at mountain slopes or from the ground. Mining activities Mining operations in Sibuyan have started since 2005, when a barangay of San Fernando endorsed mining projects in their area, believing that this will create jobs for residents, although exploration of the area began as early as 1972.

The Sibuyanons Against Mining advocacy group, with the Sibuyan Island Sentinels League for Environment Inc. (Sibuyan ISLE), has been fighting for the conservation and protection of the island against mining activities considering its vast impact on the ecology, culture and society of the island. 2023 Altai Philippines Mining Corporation protest In December 2022, the government issued a mineral ore export permit to the Altai Philippines Mining Corporation (APMC), allowing the company to bulk test 50,000 metric tons of ore. On January 2023, Sibuyan residents set up a barricade to protest APMC operations, saying the extraction of nickel ore will disrupt the island’s intact ecosystems. On February 3, 2023, according to the environmental advocacy organization Alyansa Tigil Mina (ATM), protesters formed a human barricade intended to stop APMC trucks carrying nickel ore from leaving the San Fernando port, but the trucks forced their way through the
