Admiralty Islands lowland rain forests

Les forêts humides de plaine des îles de l'Amirauté couvrent les îles volcaniques de l'Amirauté, en Papouasie-Nouvelle-Guinée, qui constituent la province de Manus, dans la région des Îles du pays, un archipel isolé situé à environ 280 kilomètres au large de la côte nord de la Nouvelle-Guinée. La forêt tropicale humide de plaine domine les plus grandes îles, avec des arbres de canopée caractéristiques comme Calophyllum, Barringtonia et Terminalia, bordées de zones de broussailles côtières de Sararanga et Pandanus. Le climat est chaud et humide toute l'année, avec des maximales diurnes proches de 30 à 32 degrés Celsius, des nuits plus fraîches et environ 3 400 millimètres de précipitations annuelles qui culminent pendant la saison humide de juin à août. Le long isolement par rapport à toute masse continentale a produit un endémisme remarquable, dont plusieurs oiseaux endémiques comme la brève superbe et le rhipidure de Manus, la roussette de l'Amirauté et l'escargot vert émeraude, le premier escargot terrestre classé vulnérable par l'UICN. L'exploitation forestière commerciale et la conversion des forêts exercent désormais une forte pression sur les forêts restantes, en particulier à l'intérieur de l'île de Manus.

Utilisez ceci comme schéma général de plantation pour la région : Forêts chaudes, humides et très productives - dont les forêts tropicales humides - aux canopées fermées, aux saisons de croissance quasi continues toute l’année et à la biodiversité terrestre la plus riche de la Terre. La faible saisonnalité et de fortes précipitations entretiennent une végétation dense et étagée, de la canopée jusqu’au sol forestier. Pour vos décisions de jardin, affinez selon les contraintes de lumière, d'eau, de sol et de taille adulte de votre site.

Banda Sea Islands moist deciduous forests

The Banda Sea Islands moist deciduous forests cover a scattered archipelago in southeastern Indonesia, spanning the Tanimbar Islands, the Kai Islands, and the Barat Daya Islands (except Wetar) within Wallacea, the transition zone lying between the Asian and Australian faunal realms. Its forests form a mosaic of evergreen and semi-evergreen rain forest, moist deciduous forest, and dry deciduous forest, with characteristic Australo-Melanesian trees such as Dillenia, Pometia, Manilkara, Inocarpus, Heritiera, Diospyros, Garcinia, and Myristica. The climate is a tropical monsoon regime of two seasons: a wetter, more humid west monsoon running from mid-December to June, followed by a drier east monsoon. Despite the small size of these islands, the ecoregion supports an exceptional 21 endemic bird species alongside 22 mammal species, with endemic birds such as the Tanimbar cockatoo and blue-streaked lory threatened by introduced rats and cats. Among its native plants, Myristica includes the nutmeg tree (Myristica fragrans), long valued for the spices nutmeg and mace.

Biak-Numfoor rain forests

The Biak-Numfoor rain forests cover a cluster of Indonesian islands in Papua Province, chiefly Biak, Supiori, and Numfoor along with smaller islands of the Padaido group, lying within Cenderawasih Bay north of Yapen and the New Guinea mainland. Original vegetation is lowland tropical wet evergreen forest, divided between alluvial forests on flatlands and river valleys and hill forests on the slopes, with multi-tiered canopies whose dominant emergents include Pometia pinnata and species of Ficus, Alstonia, and Terminalia. The climate is tropical, humid, and consistently wet, with temperatures varying little through the day or year. These islands hold the highest concentration of endemic birds of any single area in New Guinea, and the brilliantly patterned Biak emerald monitor lizard serves as the ecoregion's flagship species; large coastal stands of Calophyllum occur in northern Biak, and the lowland forests shelter an endemic palm, Manjekia maturbongsii. For gardeners, native ornamentals here include Calophyllum, Diospyros, Garcinia, and Myristica.

Buru rain forests

The Buru rain forests cover Buru Island, the third-largest of Indonesia's Maluku (Moluccas) Islands, set between the Banda and Seram Seas, where two mountain ranges rise to about 2,700 meters. Dense tropical evergreen and semi-evergreen forest blankets much of the island, dominated by tall, straight dipterocarp trees in the genera Hopea, Shorea, and Vatica, with cool, rainy montane forest taking over above roughly 800 to 900 meters and fire-resistant paper-bark (Melaleuca cajuputi) holding the drier ground. The climate is equatorial and monsoonal, with a rainy season running from October to April and the heaviest rain falling in the mountains. The ecoregion is rich in endemic wildlife found nowhere else, including the curve-tusked Buru babirusa, ten Buru-endemic birds such as the Buru racket-tail, and the flagship Buru opalescent birdwing butterfly, though selective logging and swidden farming continue to degrade the forest. Gardeners may recognize native genera with ornamental kin here, including insectivorous Nepenthes pitcher plants on the southwest limestone karst and the aromatic paper-bark Melaleuca.

Central Range Papuan montane rain forests

The Central Range Papuan montane rain forests cloak the mountain spine of New Guinea, running along the Central Cordillera from Indonesia in the west into Papua New Guinea in the east, generally between about 1,000 and 3,000 meters elevation. Vegetation shifts with altitude: lower montane forests hold oaks of the beech family such as Castanopsis acuminatissima and Lithocarpus alongside laurels, Elaeocarpus, and tall stands of Araucaria, while upper slopes are dominated by moss-draped evergreen southern beech (Nothofagus) and the highest forests turn to ancient conifers like Podocarpus, Dacrycarpus, and Papuacedrus mixed with myrtle-family trees. The climate is humid, tropical, and ever-wet, with rainfall exceeding 2,500 mm annually across most of the highlands and surpassing 7,000 mm in the wettest catchments, and temperatures averaging around 18 degrees Celsius and cooling with elevation. These highlands are a global hotspot for birds-of-paradise and carry exceptionally high endemism in mammals, birds, and vascular plants, though only roughly 14 percent lies in protected areas such as Lorentz National Park. For gardeners, the region is the native home of ornamental conifers including Araucaria and Podocarpus.

Halmahera rain forests

The Halmahera rain forests cover Halmahera and its neighboring islands, including Bacan, Morotai, the Obi Islands, Ternate, Tidore, and Gebe, in the North Maluku province of eastern Indonesia. These mountainous, partly volcanic islands belong to Wallacea, a group that sits in the Australasian realm but was never joined to either Australia or Asia, so its plants and animals mix elements of both worlds and include many species found nowhere else. Tropical lowland and montane forest dominates, ranging from evergreen to semi-evergreen rainforest, with drier stands in southern rain shadows; characteristic trees include dipterocarps such as Shorea assamica and Vatica rassak. The climate is a tropical rainforest climate. The ecoregion is rich in endemic birds and is the home of the standardwing bird-of-paradise as well as Wallace's giant bee, the world's largest bee. For gardeners, this is the native range of two famous spice trees, clove (Syzygium aromaticum) and nutmeg (Myristica fragrans).

Huon Peninsula montane rain forests

The Huon Peninsula montane rain forests cloak the steep highlands of the Huon Peninsula in northeastern New Guinea, within the Madang and Morobe Provinces of Papua New Guinea, rising across the Finisterre, Saruwaged, and Cromwell and Rawlinson ranges. Above about 1,000 meters the slopes carry tropical montane evergreen forest where broadleaf trees predominate, with conifers appearing over 2,000 meters and becoming more abundant toward the higher peaks; characteristic woody genera include Nothofagus and Dacrydium, and the Cromwell Ranges hold the only extensive unlogged Dacrydium forests in the Southern Hemisphere. The climate is tropical wet, typical of this part of Melanesia. Long isolated from other highlands by the surrounding Ramu and Markham basin lowlands, the range has evolved a highly distinct flora and fauna, including several endemic birds such as the emperor bird-of-paradise and Huon astrapia, and the endangered Huon tree-kangaroo, the ecoregion's flagship species. For gardeners, the southern-beech Nothofagus and the southern-conifer Dacrydium native here are both genera grown ornamentally in mild, moist climates.
