Geology

The eastern islands of the archipelago are part of the Luzon Volcanic Arc. Three volcanoes from two of the islands have erupted in historical times - Camiguin de Babuyanes on Camiguin Island, Babuyan Claro Volcano and Smith Volcano on Babuyan Island.
Another small volcanic island located just NE of Camiguin Island, Didicas Volcano on Didicas Island, became a permanent island only after emerging and rising to over above sea level in 1952.

Flora and fauna

All of the islands within the island group are classified by the Haribon Foundation and BirdLife International as key biodiversity areas, or sites with outstanding universal value due to their geographic and biological importance. All of the islands within the island group have never been part of any large landmass, and thus have unique flora and fauna, most of which are found nowhere else. Research conducted by the Department of Environment and Natural Resources has found at least five faunal regions in the area, one of the highest densities of separate faunal regions in the world.
The islands are also home to the most critically endangered snake species in the Philippines, the Ross' wolf snake, and the most critically endangered bird species in the Philippines, the Calayan rail. The Babuyan archipelago, along with the nearby Batanes islands, have been designated an Important Bird Area by BirdLife International because they support significant populations of resident Taiwan green pigeons, Ryukyu scops-owls and short-crested monarchs, Chinese egrets on passage, and wintering yellow buntings.
The island group is also one of the few congregation sites for endangered humpback whales in Southeast Asia. Due to its value to the natural world and Philippine biological diversity, various scientific and conservation groups have been lobbying for its declaration as a national park and its inclusion in the UNESCO World Heritage List. Humpback whales have re-colonized the area and the Babuyan Group of Islands has become the only wintering ground for the species in the Philippines although historical records from the Babuyan Islands have not been confirmed.
