Rainforests are ecoregions that typically receive between 180 to 210 centimeters of rainfall per annum. These forest types typically have canopies that attain heights of 30 to 45 meters. Rainforests may occur in tropical or temperate zones, but are customarily characterized by elevated levels of endemism and species richness. Sunlight penetration to the forest floor is a minimal quantity, generally less than two percent of the canopy value.
Western Java rainforestsLast Updated on 2014-04-21 15:07:38The Western Java rainforests are found on one of the most active volcanic islands in the world. Once the home of the extinct Javan Tiger (Panthera tigris sondaicus), these forests still contain one of the two remaining populations of one of the world's most threatened mammal species, the critically endangered Javan Rhinoceros (Rhinoceros sondaicus). Unfortunately, only about 5 percent of the original habitat of this ecoregion remains.
This ecoregion represents the lowland moist forests (less than 1000 metres in elevation) of western Java, Indonesia. Based on the Köppen climate zone system, this ecoregion falls in the tropical wet climate zone, although as one moves eastward on Java there is increasing seasonality of precipitatio. Java probably did not exist before the Miocene (24 million years before present).
Truly born of fire, the island of Java is the result of the... More »
Tenasserim-South Thailand semi-evergreen rainforestsLast Updated on 2014-04-17 18:33:35The Tenasserim-South Thailand semi-evergreen rainforests cover the transition zone from continental dry evergreen forests common in the north to semi-evergreen rainforests to the south. As a consequence, this ecoregion contains some of the highest diversity of both bird and mammal species found in the Indo-Pacific region.
The relatively intact hill and montane forests form some of the best remaining habitat essential to the survival of Asian elephants and tigers in the Indo-Pacific region. However, the lowland forests are heavily degraded, and many lowland specialists such as the endemic Gurney's pitta survive in a few isolated reserves.
This ecoregion encompasses the mountainous, semi-evergreen rain forests of the southern portion of the Tenasserim Range, which separates Thailand and Myanmar, and the numerous small ranges of peninsular Thailand.
This ecoregion also... More »
Sulu Archipelago rainforestsLast Updated on 2014-04-17 17:47:31Although these islands represent transitional stepping stones from the island of Borneo to Mindanao in the Philippines, they have evolved their own distinctive faunas. The Sulu Archipelago rainforests are a principal historical ecoregion of these islands, although most of their habitat has been destroyed. The islands themselves are the dividing feature between the Sulu Sea and the Celebes Sea.
Almost no forest remains on Sulu, and only the eastern portion of Tawitawi is forested; this outcome has resulted from slash-and-burn practises of indigenous peoples. Furthermore, the islands are extremely politically unstable, which exacerbates a difficult conservation situation.
This ecoregion includes the main islands of Jolo (Sulu) and Tawitawi and the surrounding smaller islands from Sibutu up to but not including Basilan Island. The climate of the ecoregion is tropical wet. There are... More »
Peninsular Malaysian lowland rainforestsLast Updated on 2014-04-17 14:22:36The Peninsular Malaysian lowland rainforests ecoregion, with 195 mammal species, has the second most mammal species in the Indo-Pacific, behind the Borneo lowland rainforests. Yet most of the wide-ranging or top carnivore species lead a tenuous existence within these biologically noteworthy forests. The tiger, Asian elephant, Sumatran rhinoceros, Malayan tapir, gaur, and clouded leopard all fall into this category. As in many other tropical forests in this region, habitat loss and poaching are the two primary reasons for the decline in these and other species.
This ecoregion is comprised of the lowland moist forests of Peninsular Malaysia and the extreme southern part of Thailand. There are no clear seasons in peninsular Malaysia, and rainfall is plentiful year-round. Two monsoons punctuate the region. From October to March a northeastern monsoon brings extra rain to the eastern... More »
Palawan rainforestsLast Updated on 2014-04-17 14:03:23
Palawan represents a bridge between the Sunda Shelf and Philippine bioregions and contains faunal elements from both, as well as it own unique elements. This ecoregion, though more intact than any other region in the Philippines is under great pressure from logging interests.
This ecoregion includes the island Palawan plus Balabac, Ursula Island, and the Calamian Group. Palawan itself is the sixth largest of the Philippine Islands. The climate of the ecoregion is tropical wet. In northwest Palawan, a dry season lasts from November to May while the wet season lasts from June to October; the rest of the island experiences a short, one- to three-month dry season. The east coast becomes progressively drier than the west coast from north to south.
Palawan (along with the Calamianes and the island of Mindoro) was rifted (below water) from the Asian mainland approximately 32 million... More »
