Reference excerpt

The Timor and Wetar deciduous forests is a tropical dry forest ecoregion in Indonesia and East Timor. The ecoregion includes the islands of Timor, Wetar, Rote, Savu, and adjacent smaller islands.

Geography Timor, Wetar, Rote, and Savu are part of the Lesser Sunda Islands. The ecoregion is part of Wallacea, a group of islands that are part of the Australasian realm, but were never joined to either the Australian or Asian continents. The islands of Wallacea are home to a mix of plants and animals from both terrestrial realms, and have many unique species that evolved in isolation. Timor is the largest of the islands at 30,777 km2. Timor is politically divided; The independent country of Timor Leste is on the eastern portion of Timor, and western Timor and the other islands are part of Indonesia. Western Timor, Rote, and Savu are part of East Nusa Tenggara province, while Wetar is part of Maluku Province. The islands are mostly mountainous, and Tatamailau on Timor is the highest point at 2986 meters elevation. Wetar reaches 1,407 meters elevation.

Climate The ecoregion has a tropical monsoon climate. The islands are in the rain shadow of Australia, and are among the driest in Indonesia. Rainfall is strongly seasonal, and April through November are generally the driest months. The windward southern side of the islands and receive annual rainfall of 2000 mm or more, with a two- to four-month dry season with less than 100 mm per month. The leeward north side of the island is much drier, receiving 1000 mm or less, with nine or more dry months. Some south-facing mountain areas above 900 meters elevation are humid year-round.

Flora Forest types include lowland evergreen rain forests, montane evergreen rain forests, semi-evergreen rain forests, moist deciduous forests, dry deciduous forests, and thorn forest/scrub. Evergreen and semi-evergreen rain forests occur in high-rainfall areas on the south side of the island. Deciduous forests and thorn forests are more widespread. Little primary forest remains; most forests are secondary. Extensive burning for shifting cultivation, grazing by goats and other livestock, and tree harvesting has reduced much of the island to anthropogenic grassland and scrub, including many invasive exotic shrubs. Savannas are common in the lowlands, and are of four types – palm savanna with Borassus flabellifer, eucalyptus savanna with Eucalyptus alba, acacia savanna, and casuarina savanna. Other plant communities include coastal dune grasslands and shrublands. Sandalwood (Santalum album) and candle nut (Aleurites moluccanus) are important tree crops harvested from the wild. Sandalwood was economically important, but over-harvesting has left it scarce and critically endangered.

Fauna The ecoregion has thirty-eight mammal species. The Timor shrew (Crocidura tenuis) and Timor rat (Rattus timorensis) are endemic. Two species were believed to have been brought to the islands long ago by humans – the Northern common cuscus (Phalanger orientalis), a marsupial originating in New Guinea, and the Javan rusa (Rusa timorensis), a deer originating in Java and Bali. The ecoregion is home to 229 bird species. It corresponds to the Timor and Wetar endemic bird area. 23 species are endemic.

Extinct fauna Giant rats in the genus Coryphomys are believed to have gone extinct 1000–2000 years ago. Fossils of two species of Stegodon, an elephant relative, have been found on Timor, the most recent approximately 130,000 years old. Mid-Pleistocene fossils of a giant monitor lizard, similar in size and related to the living Komodo dragon found on Flores and neighboring islands, have also been found on Timor.

Protected areas A 2017 assessment found that 2,245 km2, or 7%, of the ecoregion is in protected areas. About half the unprotected area is still forested. Protected areas include Nino Konis Santana National Park (588.99 km²) and Kay Rala Xanana Gusmão National Park (92.31 km²) in East Timor.

Worked examples

Example 1 — a first encounter with Timor and Wetar deciduous forests

Start with the simplest possible case. Write down what Timor and Wetar deciduous forests claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Timor and Wetar deciduous forests before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Timor and Wetar deciduous forests ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Timor and Wetar deciduous forests

In research: Timor and Wetar deciduous forests appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Timor and Wetar deciduous forests in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Timor and Wetar deciduous forests is common in secondary-school and first-year university syllabi. It links to neighbouring topics Australasian ecoregions, Ecoregions of Indonesia, Ecoregions of Malesia, so understanding it makes those chapters shorter.
In everyday life: Look for Timor and Wetar deciduous forests outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
