Sibuyan
Sibuyan
is a crescent-shaped island, the second largest in an archipelago comprising Romblon
Romblon
Province, Philippines. Located in the namesake Sibuyan
Sibuyan
Sea, it has an area of 445 square kilometres (172 sq mi). The island has two prominent peaks, Mount Guiting-Guiting with a height of 2,058 metres (6,752 ft) and Mount Nailog
Mount Nailog
with a height of 789 metres (2,589 ft). The people speak the Sibuyanon dialect of Romblomanon, a Visayan language. Sibuyan
Sibuyan
has been dubbed by some local and international natural scientists as "the Galápagos
Galápagos
of Asia", because it has remained in isolation from the rest of the world since its formation and it has a very high endemism rate of both flora and fauna, notably pitcher plants and forest rodents found nowhere else. Never in its geological history has it ever been connected with any part of the Philippine archipelago. Seismic forces pushed up a 2,000 metres (6,600 ft) peak from the earth’s crust, forming a series of smaller peaks and slopes. The peak is Mt. Guiting-Guiting (literally means "the saw-toothed mountain", in reference to its jagged ridge). Because of the steep slopes, much of its original forest remains untouched, and the rest is the island as we find it today. Primary forests cover 140 square kilometres (54 sq mi), which is 33% of the land area of Sibuyan. However, most of the lower altitude forest has been logged or is secondary. Mt. Guiting-guiting Natural Park (equivalent to the IUCN
IUCN
category of National Park) was established to protect these forests, which are mainly in the centre and north of the island, and covers an area of 157 square kilometres (61 sq mi) out of Sibuyan’s total area of 445 square kilometres (172 sq mi). The park features a scenic landscape with twin towering peaks set amidst closed canopy forests. Its forests remain largely intact, and include the entire elevational gradient from lowland dipterocarp forest (at 200 to 900 m) and mangroves, through montane forest (above 700 m) to mossy forest, heathland and montane grassland around the peaks. The entire island has been pushed by various scholars to be included in the tentative list of the Philippines

The island is shared by three municipalities; Cajidiocan, Magdiwang, and San Fernando. The peoples of the three municipalities have converged numerous times against mining operations in Sibuyan

island as the industry endangers the unique biodiversity of the entire island. The convergence, which included both poor and rich residents, have formed the Sibuyanons Against Mining. The locals of the island are one of the fiercest and most widely-acclaimed environmentalists in the Visayas
Visayas
region of the Philippines, having been praised by the environmentalists of Palawan, Manila, and the Dinagat Islands. Biodiversity[edit]

Sibuyan
Sibuyan
has a rich biodiversity of flora and fauna which are threatened by an emerging aggressive promotion of mining industry by the country's government. Exact figures on numbers of total plant species are hard to give, as biologists stumble upon species yet unidentified by the scientific community. In one study, the National Museum identified 1,551 trees in a single hectare, with 123 species of trees, and of this number, 54 are found nowhere else in the world. Hence, it has been proclaimed as one of the world’s most diverse and dense forests.[1] There are estimated to be 700 vascular plant species on the island. 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. Current environmental issue[edit] Sibuyan
Sibuyan
Island remains as one of the most unspoiled ecosystems in the Philippines
Philippines
and the world.[citation needed] 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. The Sibuyanons Against Mining advocacy group, with the Sibuyan
Sibuyan
Island Sentinels League for Environment Inc. ( Sibuyan
Sibuyan
ISLE),[2] 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. References[edit]
