The Western Guinean lowland forests ecoregion is a tropical moist broadleaf forest ecoregion of West Africa. It is centered on Liberia, with portions in surrounding countries. It is the westernmost tropical rainforest in Africa, and has high levels of species endemism, with over 200 species of endemic plants.
The Hainan Island monsoon rain forests ecoregion covers mountainous interior of Hainan Island in China. The tropical forests receive over 1,000 mm/year of rain, heavily concentrated in the summer rainy season. The island has high levels of biodiversity, with over 4,200 plant species, 630 of which are endemic to the island. The region is under ecological pressure from deforestation for agriculture and timber extraction.
The Hokkaidō deciduous forests ecoregion covers the northern and southern coasts of the island of Hokkaido, the northernmost of the main islands of Japan. The region sits in the transition zone between the colder subarctic forests to the north and the more temperate forests to the south. Characteristic trees include Mongolian oak, Basswood, and Ash trees.
The Luang Prabang montane rain forests ecoregion covers elevations over 800 meters in the Luang Prabang mountains that straddle the border between northern Thailand and north-central Laos, and the highlands that stretch eastward across north-central Laos. While much of the forest cover has been degraded, there are still large areas of relatively untouched forest.
The Northern Annamites rain forests ecoregion covers the rugged and relatively unexplored northern Annamite Mountains of central Laos and Vietnam. There are high numbers of endemic plant species, and the relative remoteness and isolation of the area supports many rare and endangered animals. Rainfall is somewhat less than the lowland rainforest of the lower elevations in Vietnam, and the temperatures slightly cooler due to the higher elevation.
The Northern Thailand–Laos moist deciduous forests ecoregion follows the upper course of the Nan River in northern Thailand and the Mekong River in Laos. This area has the highest proportion of tree cover in Thailand, with many forests dominated by Teak. The river valleys have been under pressure from human use: agriculture, teak plantations, and hunting have reduce plant and animal presence.
The Eastern Java–Bali montane rain forests ecoregion covers the higher altitude mountain rainforests on the eastern side of the island of Java, and most of the center of the island of Bali in Indonesia. The region has a number of active volcanoes, but is under pressure from growing human populations pushing into higher elevations and more marginal land. With elevations rising from sea level to 3,426 metres (11,240 ft), and precipitation varying between rainforest and drier forest levels, the area has many different forest types – evergreen, deciduous and semi-alpine.
The Sumatran lowland rain forests ecoregion covers the lowland forests running the length of the island of Sumatra in Indonesia. The region is one of exceptionally high biodiversity, similar to Borneo and New Guinea islands. Many endangered mammals species are present, and over 450 species of birds have been found in the region. In recent years, illegal logging and human encroachment have put great strain on this ecoregion.
The Sumatran montane rain forests ecoregion covers the mountainous elevations of the Barisan Mountains Range that runs the length of the southwestern side of the island of Sumatra in Indonesia. The ecoregion is almost completely surrounded by the lower elevation Sumatran lowland rain forests. The area is one of very high biodiversity - because of the relative isolation, and variety of forest types, there are 7 endemic species of mammals and eight endemic species of birds.
The Mindanao montane rain forests ecoregion covers the montane forests - the zone between the lowland forest and the treeline - in the mountains on the island of Mindanao in the Philippines. Because the ecoregion covers only elevations above 1,000 metres (3,300 ft), it exists in seven discontinuous patches surrounded by lowland rainforest. Biodiversity is high, both because of the isolation of separate mountain ranges that have led to species variation within the island, and because of the altitude zonation. Because most of the surrounding lowland forest has been cleared for human use, the montane regions have become an important refuge for rare and endemic species.
The Greater Negros–Panay rain forests ecoregion covers the central Visayan Islands in the Philippines, including the islands of Panay, Negros, Cebu, Masbate, Sibuyan, Ticao, Guimaras, Romblon, Tablas, Siquijor, and Bohol, but excludes Leyte and Samar. During the last ice age, these were all on the same island. The lack of a land bridge to Asia during the ice age kept most Asian megafauna, including elephants and tigers, from reaching the Philippines and the Visayan Islands, which hosts many unique and endemic species with some exclusive only to an island.
The Mindanao–Eastern Visayas rain forests ecoregion covers the lowland rain forests of the island of Mindanao and of the easternmost of the Visayas Islands in the Philippines. Although 63% of this ecoregion is covered with closed broadleaf evergreen forest or open forest, much of this has been disturbed in the past by human activity, and many of the rare species of the area have been relegated to the isolated areas or higher elevations.
The Sumatran peat swamp forests ecoregion covers the low-lying peat swamp forests along the northeast coast of the island of Sumatra in Indonesia. As is typical for peat swamp forests, this ecoregion lies between a thin strip of saltwater-affected mangroves on the coast, and freshwater swamps and lowland rainforest forest on better drained soils further inland. Because the peat soil has relatively low nutrient levels, this ecoregion has been less used for agriculture, but burning and clearance has degraded half of the forest.
The Palawan rain forests ecoregion covers the Palawan Island Archipelago, centered on Palawan Island, the sixth largest island in the Philippines. The islands act as an ecological bridge between Borneo and the main islands of the Philippines, even though there were channels between the islands through the last ice age when sea levels were low. Biodiversity is high in the islands, with many endemic species, and with many genera shared with Borneo to the south. Pressure from logging is a concern for the forests of this region.
The Western Java montane rain forests ecoregion covers the montane rain forest above 1,000 meters in the volcanic mountain ridges in the west of the island of Java in Indonesia. Several mammals and bird species are found only in this ecoregion, including the Javan mastiff bat (Otomops formosus) and the Volcano mouse (Mus vulcani). Only about one-fifth of the original rainforest remains in its original state, as human pressures are encroaching on the mountain slopes.
The Western Java rain forests ecoregion covers the lowland rain forests below 1,000 meters in elevation in the western half of the island of Java in Indonesia. There are a variety of forest types - evergreen, semi-evergreen, moist deciduous, and even some patches of freshwater swamp. The forests have degraded by conversion of the low areas to agriculture, and by logging. National parks protect some of the last remaining untouched rain forest. A number of endangered mammals are found in the ecoregion, including the Javan rhinoceros, the silvery gibbon, and the Javan surili.
The Central American Atlantic moist forests ecoregion covers the lowland coastal forests of Honduras, southeast Guatemala, and the eastern forests of Nicaragua. Half of the ecoregion is closed-canopy tropical broadleaf evergreen forest, with tree heights reaching 50 meters. This ecoregion has the largest single fragment of natural forest in Central America, with a size of 14,629 square kilometres (5,648 sq mi). The total area is 89,979 square kilometres (34,741 sq mi).
The Costa Rican seasonal moist forests ecoregion covers the Pacific Slope of the volcanic mountain range of northwestern Costa Rica and the extreme south of Nicaragua. The area has a distinct dry season during which the characteristic deciduous trees drop their leaves. The forests themselves have been highly degraded in the past by human conversion to agriculture and settlement. The Costa Rican capital city of San Jose is in the middle of this ecoregion.
The Trinidad and Tobago moist forests ecoregion covers most of Trinidad Island and Tobago Island near the coast of South America where the southeastern Caribbean Sea meets the Atlantic Ocean. Small portions of the islands around river estuaries and coastal lowlands are mangroves or dry forests. Species diversity is very high, in particular for plants and birds. Tobago, being much smaller, has fewer species.
The Lesser Antillean dry forests ecoregion covers the dry forests of the coastal lowlands of the Lesser Antilles, where the eastern Caribbean Sea meets the Atlantic Ocean. These forests generally form a band around the interior wet forests of higher elevations, and because they are often flat, they are under the most pressure for human settlement and agriculture.
