PHILIPPINE BIODIVERSITY STATUS OUR LIVING AND NON-LIVING RESOURCES  PHILIPPINES: high species diversity and high endemicity ENDANGERED ENDEMIC A species present in An organism such small numbers exclusively native to a that it is at risk of place or biota extinction. WHY IS THIS SO: the patchwork of isolated islands, the tropical location of the country, and the once extensive areas of rainforest The Birds The Philippines is home to some of the world's most exotic birds Scientists have documented 577 bird species around the Philippine archipelago. Of this number, 185 species are endemic to the country. The Bird Life International listed 116 of them as "threatened" or "near- threatened". Causes of Endangerment of Birds They are large, easily seen birds and thus vulnerable to being shot; They are trapped for pets or food; Their habitat has been destroyed, especially lowland virgin forest; and They are restricted to one or two islands. The Philippine Eagle : Pithecophaga jefferyi Lives in the rainforests of Isabela, Samar, Leyte and Mindanao. It has similarities with Papua New Guinea's Harpy Eagle (Harpyopsis novaeguinea). It lives on large snakes, hornbills, civet cats, flying lemurs and monkeys - the reason why it is also called monkey-eating eagle. With an estimated population of 100 to 300 today, the Philippine eagle is in danger of extinction. It is one of the 400 exotic bird species in the Philippines, which, if not protected, would disappear from the face of the Earth.  Endangered… The Philippine or Red-vented Cockatoo (Cacatua haematuropygia) The Palawan Peacock Pheasant (Polyplectron emphanum) Endangered… The Sulu Hornbill (Anthracoceros montani) The Mindoro Imperial Pigeon (Ducula mindorensis) Sulu hornbill and Cebu black shama, the Philippine Eagle might follow the Cebu flowerpecker which is now presumed extinct. Endangered… Cebu Black Shama Cebu Flowerpecker (now presumed extinct)  Endemics…and Endangered Visayan wrinkled hornbill Aceros waldeni The Negros Bleeding Heart Pigeon Gallicolumba platenae Red-bellied pitta (Pitta erythrogaster)  Endemics…and still widespread Grand Rhabdornis One of the world's rarest mammals lives in the dwindling forest of Panay Island: Philippine spotted deer (Cervus alfredi), considered by many as the most endangered deer in the planet Deer that cannot be found elsewhere: the Calamian hog deer or Calamian deer have longer and darker legs, compared with other hog deer. By 1996, its population further declined to only about 900, prompting conservationists to declare it as an endangered species. The Mammals Unique pygmy water buffalos (Bubalus mindorensis) endemic to Mindoro listed as one of the ten most endangered species in the world. From 10,000 heads in the 1900's, population went down to 369 heads in the late 1980's to as few as 20 heads roaming in the wild today The Mammals  Philippine tarsier (Tarsius syrichta) measures only about twelve centimeters in length. Its two big eyes cannot move and do not have a tapetum - the upper protective tissue; can turn its head 180 degrees. Found in the islands of Samar, Leyte, Bohol and Mindanao, the Philippine tarsier got its name from its elongated tarsus bone. Today, there are only about 1,000 tarsiers inhabiting the wilds of Corella town in Bohol province where the biggest concentration of these rare animals was once reported. Ensuring the continued existence of the Philippine tarsiers is the Philippine Tarsier Foundation Inc. The Mammals  The Palawan bearcat population is threatened by human activities. The Mammals  South of Palawan, lies the Balabac Island, home of the world's smallest hoofed mammal - the Philippine mouse deer. Locally known as Pilandok (Tragalus nigricans), this ruminant stands only about 40 centimeters at the shoulder level. While the mouse deer are widely distributed across Asia, their dwindling population has alarmed the World Conservation Union, which declared them as endangered in 1996. The Mammals  Dugongs or sea cows, the only herbivorous marine mammals, are often sighted in Philippine waters, particularly near Palawan province and southern Mindanao. A dugong can live more than 70 years. The Philippine government has The Mammals banned the commercial exploitation of dugong since 1991. Golden- capped fruit Bat Over the years, Acerdon jubatus these two species of giant fruit bats have roamed around the 10,000-hectare Subic Forest National Protected Area, which is considered the biggest roosting site of bats in the world. The Mammals The smallest bat in the world is the Philippine bamboo bat (vespertilionid), which belongs to the vespertilionid family. This bat measures about four centimeters (1 1/2 inches) in length and has a wingspan of 15 cm. Approximately, it weighs 1.5 grams (1/20 ounce). The Mammals The Mindoro Pallid Flying Fox smallest flying fox in the Philippines The Philippine tube-nosed bat, Nyctimene rabori of Negros is considered highly endangered The Mammals  Believed to have become extinct in 1970s as a result of the combination of forest bare-backed fruit bat or Dobsonia chapmani destruction, disturbance by guano miners, and hunting The Mammals  The continuous denudation of tropical forests in the country threatens the remaining population of kagwang, which used to abound in the wilderness of Basilan, Leyte, Samar, Bohol and Mindanao. Philippine government declared kagwang as an endangered species The Mammals and banned its commercial exploitation.  Northern Luzon Giant Cloud Rat Phloeomys pallidus The Visayan Warty Pig Sus cebifrons Widespread in northern and central Luzon 1994: Endangered From sea level to high mountains (at least 2000 m), in primary and 1996 - 2004: Critically secondary forest and heavily disturbed Endangered scrub The Mammals  Crocodylus porosus, it is different from Mindoro's freshwater crocodile (Crocodylus mindorensis) There were tales that a 27-foot saltwater crocodile was killed near Lake Taal in Batangas in 1823. It reportedly took 40 men to bring the body ashore. Amphibians and Reptiles  Busuanga, Culion, and Palawan Philippine flat- headed frog Barbourula busuangensis inhabits clear, unpolluted swift-flowing mountain streams and rivers in lowland rainforests where it usually floats near the surface of the water unless disturbed, when it will hide under submerged rocks Amphibians and Reptiles  southern Luzon and Catanduanes Island in the Philippines, where it inhabits the forested slopes of low mountains Gray’s monitor Varanus olivaceus Amphibians and Reptiles  Loggerhead (Caretta caretta) Olive Ridley (Lepidochelys olivacea) Leatherback sea turtle Philippine pond turtle Heosemys leytensis Philippine Green turtle Hawksbill sea turtle Amphibians and Reptiles  Donsol, a fishing town in Sorsogon province, serves as a sanctuary to a group of 40 whale sharks (Rhincodon typus), which are considered as the largest fish in the world. Locally known as "butanding", whale sharks visit the waters of Donsol from November to May. They travel across the oceans but nowhere else have they been sighted in a larger group than in the waters of Sorsogon. In 1996, a marine biologist discovered that whale sharks are ovoviviparous, which means that the females produce live offspring from eggs hatched in the uterus. The Philippine government declared whale sharks as endangered species in 1998, thereby banning its plunder and exploitation. Right now, the Department of Tourism is promoting eco-tourism to protect the whale sharks in Donsol. Fish The world's smallest freshwater fish is found in the Philippines. The dwarf goby (Pandaka pygmaea) measures 1.2 centimeters or less than half of an inch, the tiniest known vertebrate. American Ichthyologist Albert Herre first discovered it in Malabon River in 1925. Fish  it would take a thousand to fill a tablespoon World's smallest commercial fish: Sinarapan (Mistichthys luzonensis) found only in Lakes Bato and Buhi in Camarines Sur province. Sinarapan grows to an average length of 1.25 centimeters, only slightly longer than the dwarf goby. Today, unabated fishing in the two lakes threatens the population of sinarapan. Fish  Sawtail Catshark Chaetodontoplus caeruleopunctatus Blue-spotted angelfish Philippine Anchovy: Dilis or Bolinao Exyrias: goby or biya Fish  More than 500 of the world's 700 coral species are found under the waters of the Philippines, which is a part of the Coral Triangle - a region in the Pacific Ocean. There are at least 50 known seahorse species in the world. They inhabit temperate and tropical waters but most of them are concentrated in the warm coastal waters of the Philippines. The seahorse's scientific genus name, Hippocampus is a Greek word, which means, "bent horse." At least 47 nations and territories around the world are involved in buying and selling seahorses. The largest known importers are China, Hong Kong, and Taiwan. Fish Among the largest exporters is the Philippines.  About 70 percent of the Philippines’ nearly 21,000 recorded insect species are found only in this hotspot. About one-third of the 915 butterflies found here are endemic to the Philippines, and over 110 of the more than 130 species of tiger beetle are found nowhere else. The Invertebrates  Tridacna gigas, one of the world's largest shells can be found under Philippine waters. Tridacna gigas grows as large as one meter in length and weighs 600 pounds The Invertebrates Pisidum, the world's tiniest shell, can be found under Philippine waters. Pisidum is less than 1 millimeter long The Invertebrates A shell called glory of the sea (Connus gloriamaris) is also found in the Philippines and considered as one of the most expensive shells in the world. The Invertebrates  Total Plant Species: 9,2536 Endemic Plant Species: 6, 091 Endemics as Percentage of World Total: 2.0 The Plants Velvet Apple, Mabolo Diospyros discolor There are more than 150 species of palms and dipterocarps in the hotspot, and around two-thirds of these are found nowhere else in the world. Among the endemic fruit trees in the Philippines are durian, mabolo, pili and bignay The Plants  Of the 1,000 species of orchids found in the Philippines, Gingers, begonias, gesneriads, orchids and 70 percent are pandans are particularly high in endemic restricted to the species hotspot. As many as 9,000 flowering plants can be found in the country The Plants
