The Huon Peninsula montane rain forests is a tropical moist forest ecoregion in New Guinea. The ecoregion covers the mountains of northeastern New Guinea's Huon Peninsula.
The ecoregion is made up of montane rain forests on the Huon Peninsula. The montane rain forests occur above 1000 meters elevation on the Peninsula's mountain ranges, which include the Finisterre (to 4,176 m), Saruwaged (to 4,122 m), and Cromwell and Rawlinson ranges. [3]
The ecoregion has a montane tropical rain forest climate.
The ecoregion's forests are of several types, which vary with rainfall, elevation, and underlying soils. Lowland hill forests occupy the foothills of the range, forming a transition between the lowland alluvial forests below and the montane forests above. Montane rain forests grow between 1000 and 3000 meters elevation. Evergreen broadleaf trees are predominant, with conifers occurring above 2000 meters elevation and becoming more abundant at higher elevations. Species composition varies with elevation. There are also areas of limestone forest. [3]
The ephiphytic moss Merrilliobryum tanianum is endemic to the ecoregion. [4]
The ecoregion has 81 species of mammals, including marsupials, murid rodents, and bats. There are Huon tree kangaroo (Dendrolagus matschiei) is endemic to the ecoregion. Several limited-range rodents, including the Highland brush mouse (Abeomelomys sevia) and Ernst Mayr's water rat (Leptomys ernstmayri), inhabit the ecoregion and neighboring highlands. [1]
There are two endemic bird species, the Emperor bird-of-paradise (Paradisaea guilielmi) and Huon astrapia (Astrapia rothschildi). [1] [5] Together with the Adelbert Range to the west (which is part of the Northern New Guinea montane rain forests ecoregion), the ecoregion forms the Adelbert and Huon ranges endemic bird area. [6]
3.7% of the ecoregion is in protected areas. Protected areas include Nusareng Wildlife Management Area (10.26 km2) and YUS Conservation Area (793.11 km2). [2]
The Solomon Islands rain forests are a terrestrial ecoregion covering most of the Solomon Islands archipelago.
The Huon astrapia, also known as Rothschild's Astrapia, Huon Bird-of-paradise, or Lord Rothschild's Bird-of-paradise, is a species of bird-of-paradise belonging to the genus Astrapia. Like most of its congeners, A. rothschildi is a rather elusive member of its genus and family.
Huon Peninsula is a large rugged peninsula on the island of New Guinea in Morobe Province, eastern Papua New Guinea. It is named after French explorer Jean-Michel Huon de Kermadec. The peninsula is dominated by the steep Saruwaged and Finisterre and Cromwell Mountains. The nearest large town is the Morobe provincial capital Lae to the south, while settlements on the north coast include the former German town of Finschhafen, the district capital of Wasu, Malalamai and Saidor with its World War II era Saidor Airport.
The São Tomé, Príncipe, and Annobón forests, also known as the São Tomé, Príncipe, and Annobón moist lowland forests, is a tropical moist broadleaf forest ecoregion that covers the islands of São Tomé and Príncipe, which form the island nation of São Tomé and Príncipe, as well as the island of Annobón, which is part of Equatorial Guinea.
The Southwestern Arabian montane woodlands is a xeric woodland ecoregion in the southwestern Arabian Peninsula.
The Cameroonian Highlands forests, also known as the Cameroon Highlands forests, are a montane tropical moist broadleaf forest ecoregion located on the range of mountains that runs inland from the Gulf of Guinea and forms the border between Cameroon and Nigeria. This is an area of forest and grassland which has become more populous as land is cleared for agriculture.
The New Guinea Highlands, also known as the Central Range or Central Cordillera, is a long chain of mountain ranges on the island of New Guinea, including the island's tallest peak, Puncak Jaya 16,024 ft (4,884 m), the highest mountain in Oceania. The range is home to many intermountain river valleys, many of which support thriving agricultural communities. The highlands run generally east-west the length of the island, which is divided politically between Indonesia in the west and Papua New Guinea in the east.
The Mizoram–Manipur–Kachin rain forests is a subtropical moist broadleaf forest ecoregion which occupies the lower hillsides of the mountainous border region joining India, Bangladesh, and Burma (Myanmar). The ecoregion covers an area of 135,600 square kilometres (52,400 sq mi). Located where the biotas of the Indian Subcontinent and Indochina meet, and in the transition between subtropical and tropical regions of Asia, the Mizoram–Manipur–Kachin rain forests are home to great biodiversity. The WWF rates the ecoregion as "Globally Outstanding" in biological distinctiveness.
The Central Range montane rain forests is a tropical moist forest ecoregion on the island of New Guinea. The ecoregion covers the Central Range of the New Guinea Highlands, which extends along the spine of the island. The montane rain forests of the ecoregion are distinct from the surrounding lowland forests, and are home to many endemic plants and animals.
The Central Range sub-alpine grasslands is a montane grasslands and shrublands ecoregion on the island of New Guinea. The ecoregion covers the highest-elevation portions of the New Guinea Highlands, which extend along the spine of the island. The high elevations support rare tropical sub-alpine and alpine habitats, including many endemic plants and animals.
The Southern Andean Yungas is a tropical and subtropical moist broadleaf forest ecoregion in the Yungas of southwestern Bolivia and northwestern Argentina.
The East African montane forests is a montane tropical moist forest ecoregion of eastern Africa. The ecoregion comprises several separate areas above 2000 meters in the mountains of South Sudan, Uganda, Kenya, and Tanzania.
The Cromwell Mountains is a mountain range on the Huon Peninsula in north-eastern Papua New Guinea.
The Vogelkop–Aru lowland rain forests is a tropical moist forest ecoregion in Indonesia. The ecoregion covers the peninsular lowlands of western New Guinea, along with the Aru Islands and other nearby islands.
The Vogelkop montane rain forests is a tropical moist forest ecoregion in western New Guinea. The ecoregion covers the mountains of western New Guinea's Bird's Head and Bomberai peninsulas.
The Northern New Guinea montane rain forests is a tropical moist forest ecoregion in northern New Guinea. The ecoregion covers several separate mountain ranges lying north of New Guinea's Central Range and south of the Pacific Ocean.
The Southeastern Papuan rain forests is a tropical moist forest ecoregion in southeastern New Guinea. The ecoregion covers the mountainous center and coastal lowlands of the Papuan Peninsula.
The Southern New Guinea lowland rain forests is a tropical moist forest ecoregion in southeastern New Guinea. The ecoregion covers portions of New Guinea's southern lowlands.
The Carolines tropical moist forests is a tropical and subtropical moist broadleaf forests ecoregion in Micronesia. It includes the central and eastern Caroline Islands in the Federated States of Micronesia.
The Yapen rain forests is a tropical moist forest ecoregion in Indonesia. The ecoregion covers the island of Yapen and smaller neighboring islands which lie north of New Guinea.
