NaturalBiosphere Reserve
Encompassing the entire Province of Palawan, the Palawan Biosphere Reserve is an archipelago comprising one long main island and 1,700 smaller islands around it. It is known as the Philippines' "last ecological frontier", the biosphere reserve is rich in natural resources and biodiversity, containing 105 of the 475 threatened species in the Philippines, several of which are endemic. Its ecosystems are similarly diverse, encompassing old-growth and second-growth tropical rainforest, karstic limestone areas, forest over ultramafic rocks, casuarinas and beach forest. Palawan Biosphere Reserve is also home to approximately 57 ethnolinguistic groups, including three Indigenous peoples: the Tagbanua, Palaw'an and the Batak.
