Ecosystem of Henderson Island
The only forested atoll with an intact ecosystem in the world. Endemic species – 9 species of plants and all 4 species of land birds. Numerous invertebrates are endemic, although they are poorly researched. Island is not walkable – it is covered with thicket and rugged limestone peaks.
Le Noir Pre orchid meadow
Unique orchid meadow with one of the largest populations of Jersey orchid (Anacamptis laxiflora) and three more species of orchids. Flowering in May and June.
The Dales of Christmas Island
Seven deep valleys formed by spring streams, closer to the sea turning into deep ravines cut in limestone. Above, at the discharge of springs they have flooded the forest dominated by enormous Tahitian chestnuts (Inocarpus fagifer). These pools in the forest form the largest freshwater basin on the island. Endemic plants.
Hosnies Spring mangroves
120,000 years old grove of mangroves some 24 – 37 m above the sea level. Mangrove ecosystems traditionally grow in shallow seawater – but here, as the sea level decreased, mangroves were fed by springs. This is unique case in the world. This 3,300 m² large area (core part, 202 ha in size) contains the oldest trees of Bruguiera gymnorrhiza and Bruguiera sexangula – 30 – 40 m tall, with trunk diameter up to 80 cm. There are mangroves of other species growing well above the sea level elsewhere on the island.
Christmas Island crab forest
The forest of Christmas Island is unique in the world due to dominant species – some 50 – 100 million red crabs (Gecarcoidea natalis) – clearing the forest floor of leaves and other organic matter. These crabs are endemic to Christmas Island. Once per year they migrate to the sea to lay their eggs, on the way blocking the roads and paths.
Norfolk Island subtropical rainforest
The last remnant (5 km²) of the unique Norfolk Island rainforest, protected by a national park. Here grow many unique endemic plants including the tallest tree fern of the world (Cyathea brownii, up to 20 m tall), Norfolk island palm (Rhopalostylis baueri), endemic orchid, and last natural stands of Norfolk pine (Araucaria heterophylla). Here lives also endemic Norfolk Parakeet (Cyanoramphus cookii), Norfolk Gerygone (Gerygone modesta), slender-billed White-eye (Zosterops tenuirostris), endemic land snails and others – in total some 50 endemic species of animals and plants.
89.9 m tall Noble Fir in Goat Marsh (dead)
The highest known specimen in species (Abies procera Rehder 1940) in the 1990ies, its height was 89.9 m (18). The tree was dead in 1996 and has fallen since then. Another, tallest ever recorded noble fir was 99.06 m tall.
Sir Vim – (White Knight) the tallest manna gum
The highest manna gum (Eucalyptus viminalis). 91,3 m high, diameter 3.30 m (girth 11.0 m), volume 180 m³. One of three trees that are known as White Knights.
