Outstanding ecosystems around the world
Wondermondo is proud to introduce to a list which is something unique by itself – a list of 66 unique and unusual ecosystems of the world. As always, this list is not exhaustive and any interested person would add here ecosystems to his own likings. But ecosystems listed below are by no means unique:

Australia and Oceania
- Baie des Tortues – New Caledonia, South Province. Visually very impressive and striking grove of the rare Araucaria luxurians trees at the beach.
- Christmas Island subtropical forest – Australia, Christmas Island. Island covered with tropical rainforest with numerous endemic species of plants and animals. Unique due to some 50 – 100 million red crabs (Gecarcoidea natalis Pocock) – dominant species, clearing the forest floor of leaves and other organic matter.
- The Daintree Rainforest – Australia, Queensland. Possibly the oldest rainforest in the world, growing 135 million years. Largest continuous rainforest in Australia, 1,200 square kilometres large, extremely high biodiversity. Contains unique, endemic primitive flowering plants.
- Elizabeth Springs – Australia, Queensland. Remote springs in arid region, where over the last 1.8 million years has developed a unique ecosystem with endemic species, such as a fish – Eliabeth Springs goby (Chlamydogobius micropterus Larson), snail etc.
- Fraser Island – Australia, Queensland. The largest sand island in the world, 1,840 km². Contains dunes up to 24 metres high, tall rainforest growing at elevations up to 200 metres, unique ‘vallum’ heaths and more than 100 unique, crystal clear dune lakes retained in the sand by organic matter deposits.
- Haleakalā silversword grove – United States, Hawaii, Maui. This unusual plant grows only in alpine desert on the top of Haleakalā volcano. The succulent plant grows up to 2 metres high if counted the tall flower stalk.
- Jellyfish Lake (Ongeim’l Tketau) – Palau, Eil Malk in Rock Islands. Unique marine lake, has underground connection to the sea. Stratified in two layers which do not mix. Isolated from the sea 12,000 years and contains a distinct population of two species of jellyfish – endemic Mastigias sp. and most likely endemic Aurelia sp. Millions of these jellyfishes make strict daily migration around the lake. Several more similar lakes in nearby islands but Jellyfish Lake is the only one open to tourists.
- Lord Howe Island – Australia. This remote, 56 km² large Australian island has its own ecoregion where half of plants and some birds and other animals are endemic. Unique characteristics is diverse glowing mushrooms in the forest, some bright enough to be used for reading in night. Endemic kentia palms are popular, beautiful houseplants.
- Mount Bosavi crater – Papua New Guinea, Southern Highlands Province. Crater in extinct volcano, some 4 km wide and 1 km deep. In 2009 here were discovered 40 new, endemic species, including 82 cm long Bosavi Wooly Rat.
- Nihoa Island – United States, Hawaii. Small island (70 ha) with its own species of palm, several endemic bird species, flowers and giant crickets.
- Palm Valley – Australia, Northern Territory, near Alice Springs. Oasis in the middle of enormous desert, the only place in the central part of Australia where grow palms: the rare Livistona mariae as well as other rare plants. Ecosystem is fed by spring water. It is likely that palms were brought here by people some 15 – 30 thousand years ago.
- Tiae dry forest – New Caledonia, Northern Province, near Pouembout. One of the last remaining stands of New Caledonian dry forest, also one of the last stands of one of the most beautiful flowering plants – Ixora margaretae ((Hallé) Mouly & B.Bremer), known also as Captaincookia margaretae Hallé.
- Tree heath south of Freycinet Estuary – Western Australia, Shark Bay. Unique biotope with at least 51 endemic species.
- Vailulu’u Eel City and Moat of Death – American Samoa, Nafanua volcano. Group of hydrothermal vents inhabited by numerous eels (Dysommina rugosa). This is unusual – in general vertebrates do not live near hydrothermal vents.
- Wooramel Seagrass Bank – Western Australia, Shark Bay. The largest seagrass grove in the world, covers 1,030 square kilometres.
- Geothermal areas of Cryptogam Ridge – Antarctica. Here geothermal heat has been keeping ice-free areas of soil. Over time in this isolated area have developed endemic species of microorganisms, as well as mosses and liverworts.
- Lake Vostok – Antarctica. Largest subglacial lake in Antarctica, similar in size to Lake Ontario, up to 1 kilometer deep, with area 15,000 km². Lake water is oversaturated with oxygen, exceeding the level of oxygen in ordinary freshwater lakes 50 times. Lake has been frozen for half a million years at least and here most likely has been developed unique habitat of microorganisms. This habitat has not been reached and investigated yet.
- Penguin colony of Lusitania Bay – Australia, Macquarie Island. This subantarctic island has several endemic plant and animal species and unusually looking biotopes of megaherbs. But especially impressive is the giant colony of royal penguins (Eudyptes schlegeli Finsch.) – the island is the only known breeding ground of these beautiful birds. Lusitania Bay colony recently has been fully occupied and penguins are coming to other parts of the island as well. In total it is estimated that there are 0.5 – 3 million penguins breeding in this island.
- Kairei hydrothermal vents – Indian ocean, Central Indian Ridge, approximately 2,420 m deep. Group of hydrothermal vents with very high H² concentration. It is possible that the unique ecosystem around these vents closely resembles the ancient ecosystems (consisting mainly of microorganisms) which existed on Earth in the seas before the photosynthesis process started. This unique ecosystem exists due to specific geological conditions around the vents. Here lives also a unique gastropod with a shell made of iron oxides.
- Lost City – Atlantic ocean, Atlantis Massif. Unique field of black smokers – hydrothermal vents with some 30 calcium carbonate towers – each 30 – 60 meters tall. Vents release methane and hydrogen, which makes them different from other known black smokers. One of the most unique ecosystems of microorganisms developed in abiotic conditions.

Definitions of words ecosystem and biotope are somewhat ethereal and elusive.
Biotope is rather small area with uniform environmental conditions and specific community of life. For years there is ongoing identification and classification of biotopes and their aggregations with hundreds of them listed around the world.
From one side – this brings in some order, for example, lays foundation for proper planning of nature conservation areas. From the other side – too often nature does not fit in classification systems – at some moment every single corner seems to be a biotope on its own.
In Wondermondo we can freely set these worries aside. Here are examined those biotopes and ecosystems which ARE unique and should be conserved (often – with some management such as grazing).
Here are described those unique ecosystems and biotopes which:
- Have striking, unusual looks. Good example is forest of Dragon’s Blood Trees – Rokeb di Firmihin (Yemen). Most people don’t imagine that something like this is possible on Earth.
- Just look unusually beautiful, for example the endless sea of flowers in Skilpad Wild Flower Reserve (South Africa).
- Are located in unusual place. Example: northernmost forest in the world (Ary-Mas and Lukunsky grove in Russia) are in the middle of endless tundra.
- Are shaped by unique processes. Lake Vostok in Antarctica is oversaturated with oxygen which in low temperatures and under high pressure most likely serves as a habitat for yet unknown organisms to be discovered somewhere in future.
- Contain unusually high number of endemic species – found only here. Thus mere 240 metres long Movile Cave (Romania) contains 33 species found nowhere else on Earth.
- Contain large number of representatives of very rare species. The small Aldabra is virtually dominated by Aldabra Giant Tortoise and this animal actively shapes the ecosystem of island.
- Are unique in some other way.
The sight of the gathering of countless penguins or antelopes is very fascinating and intriguing. There are locations in the world where such gatherings are permanent or regular – and location with intriguing sights belongs to landmarks.
