Reference excerpt

The Solomon Islands rain forests are a terrestrial ecoregion covering the Solomon Islands (archipelago).

Geography The ecoregion covers the Solomon Islands archipelago, which is divided between the countries of Solomon Islands and Papua New Guinea. The archipelago's northern islands, Bougainville and Buka, are part of Papua New Guinea. The rest of the archipelago is within the nation of Solomon Islands. The ecoregion excludes the eastern islands of the nation of Solomon Islands, the Santa Cruz Islands, which lie in the Vanuatu rain forests ecoregion together with the neighbouring archipelago of Vanuatu. The archipelago extends approximately 1450 km from northwest to southeast, between 5° and 12° South latitude. Bougainville is the largest island, about 200 km long and from 50 to 60 km wide with an area of almost 9000 km2. The island has a central mountain range, the northern part of which is known as the Emperor Range, and the southern part, separated by a lower saddle, as the Crown Prince Range. Mount Balbi in the Emperor Range, at 2,715 metres elevation, is the highest peak in the archipelago. Volcanic rocks are common, with dating back approximately 30 million years. The Panguna mine in the Crown Prince Range, currently closed, is one of the largest copper mines on earth. The Keriaka Plateau in northwest Bougainville, south of Mount Balbi, is a karst plateau formed of weathered foraminiferous limestone dating to the lower Miocene. Buka Island lies northwest of Bougainville, separated by a narrow strait. Much of the island is made up of uplifted Pleistocene coralline limestone. The rest of the archipelago extends southeast of Bougainville as a double chain. The outer or northeastern chain comprises the islands of Choiseul, Santa Isabel, and Malaita, which are each about 200 km long and 30 km wide. The islands have mountainous interiors extending above 1000 m on Choiseul, 1200 m on Santa Isabel, and 1300 m on Malaita. The inner chain extends from Shortland Island, 20 km southeast of Bougainville, and includes Vella Lavella, Ganongga, Kolombangara, the New Georgia Islands (New Georgia, Rendova, Vangunu, and Nggatokae), the low coralline Russell Islands, Guadalcanal, and San Cristobal. Guadalcanal has the highest mountains of the inner and outer chains, and Mount Popomanaseu on Guadalcanal is the highest peak outside Bougainville at 2331 metres elevation. Honiara, the capital of the Solomon Islands, is on the north shore of Guadalcanal. The inner chain islands are mostly below 1000 meters elevation, with the exception of the conical stratovolcano Kolombangara which reaches 1,770 metres. Most of the inner and outer chain islands are made up of volcanic rocks, including andesite and basalt. Guadalcanal has the most complex geology, with areas of andesite volcanics, intrusive plutonic rocks, Pliocene sedimentary rocks, and uplifted Pleistocene coralline limestone in the northern lowlands near Honiara. There are outcrops of ultramafic rock, rich in chromium and nickel, on five islands – at Santa Isabel's southern tip, on the nearby island of San Jorge, in the Florida Islands, in southwestern Guadalcanal, and in north-central San Cristobal. These rocks are toxic to many plants, and are often home to distinctive plant communities. The archipelago includes two groups of low coralline outlying islands – Ontong Java, northeast of the outer chain and 450 km north of Honiara, and Rennell and Bellona, south of San Cristobal and 250 km south of Honiara. The ecoregion is part of the Australasian realm, which also includes the neighbouring Bismarck Archipelago and New Guinea, as well as New Caledonia, Australia and New Zealand. Floristically it is the easternmost part of the Papuasia region, which includes New Guinea and the Bismarck Archipelago.

Climate The islands have a humid tropical climate. Rainfall averages between 3000 and 5000 mm annually at most sea-level stations. There is little seasonal variation in temperature, with seasonal variation in rainfall depending on the prevailing winds. The southeast trade winds are active from about March to October when the sun is north of the equator. February–March and November–December are unsettled weather periods when the islands can get drenched with convectional rains. Winds come from the northwest from December to February. The southern islands can experience tropical cyclones, which usually develop between November and April. Guadalcanal's relatively high east–west running mountains create a rain shadow effect in the island's northeastern lowlands, with lower rainfall during the southwest trade wind season than elsewhere in the archipelago. Temperatures above 700 meters elevation are generally 4 to 5 °C cooler than the lowlands, with mean annual temperatures of 22 to 23 °C. The highlands experience cloud cover during the southeast trade wind season, and windward slopes have higher rainfall than the lowlands.

Worked examples

Example 1 — a first encounter with Solomon Islands rain forests

Start with the simplest possible case. Write down what Solomon Islands rain 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 Solomon Islands rain 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 Solomon Islands rain 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 Solomon Islands rain forests

In research: Solomon Islands rain 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 Solomon Islands rain 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: Solomon Islands rain forests is common in secondary-school and first-year university syllabi. It links to neighbouring topics Australasian ecoregions, Ecoregions of Papua New Guinea, Ecoregions of the Solomon Islands, so understanding it makes those chapters shorter.
In everyday life: Look for Solomon Islands rain 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.
