Sibuyan Island has extremely high endemism largely due to its remoteness. More than half of the Island is covered with forest. Preliminary reports include that the forest density in Sibuyan is 1,551 trees per hectare making it the densest forest ever recorded in the Philippines.{{citation needed|date=August 2024}} There exists a full range of forest gradient in the Philippines consisting of mangrove, lowland, montane, mossy forests, heathland, and grassland—from the shoreline up to the summit of Mt. Guiting-Guiting,

There are approximately 700 vascular plant species, including 54 species that are endemic to the island.  These include ''[[Nepenthes sibuyanensis]]''; ''[[Nepenthes argentii]]''; ''[[Heterospathe sibuyanensis]] Becc''. (Bil-is), ''[[Agalmyla sibuyanensis]]'' (Sibuyan lipstick plant); ''[[Myrmephytum beccarii]]'' Elmer (Sibuyan ant plant); ''[[Begonia gitingensis]]'' Elmer (Guiting-guiting begonia).

A total of 130 species of birds have been recorded in the park, of which 102 are either known or presumed to be breeding residents.
