Terrain shapes and bedrock
According to COUNTRYAAH, the individual islands lie in two parallel rows in the northwest – southeast direction. They form part of a larger volcanic arch extending from the east of New Guinea to Vanuatu. The highest of the islands is Guadalcanal with the top Makarakomburu, 2,447 m asl. Other islands with peaks above 1,000 m above sea level. are Kolombangara, Malaita, San Cristóbal and Santa Isabel.
The surface of the islands is usually mountainous and uneven with volcanic craters, lavor and toughness. Some volcanoes have frequent eruptions, hot springs and solar faults. Earthquakes are common. Many of the islands have wide coastal plains, and coral reefs are found along most.
According to BRIDGAT, Solomon Islands has a tropical rainforest climate. Temperature, humidity and rainfall do not vary much during the year; however, rainfall is lower during June – September. The Southeast Passage provides the majority of precipitation, about 3,000–3,500 mm per year. The average monthly temperature is around 27 °C throughout the year, and it is rarely warmer than 32 °C.
Plant-and animal life
On the larger islands, especially in mountainous regions, there are still untouched rainforests. Often, however, the forest is shredded and replaced by a savannah-like landscape with alang-alang grass. In coastal areas and inland of smaller islands, vegetation is mostly bushland, most often the sea is coconut palm or mangrove. Especially in watercourses, screw palms are a tangible feature. Coral reefs are found around most islands.
The mammalian fauna comprises about ten species of moths and about 30 species of bats, among others. several species of flying dogs. About 130 species of land birds nest on the Solomon Islands; at least 15 of the approximately 40 endemic species now have very small populations. Among the approximately 70 species of reptiles are the delta crocodile (rare on the coasts of most islands), giant ham (Coruʹcia zebraʹta), the Pacific species (Varaʹnus iʹndicus), wormworms and fijiboor (Candoia [-do i ʹa]).
The Solomon Islands in 2011 had a national park, Queen Elizabeth National Park.
The Solomon Islands consist of eight larger volcanic islands that form two parallel chains in the northwest – southeast direction. In addition, there are a whole host of smaller islands and atolls. The larger islands are mountainous, and the highest mountain is Makarakomburu (2447 meters) on the main island of Guadalcanal.
Equatorial climate with only small seasonal variations. The average temperature for Honiara is 27 ° C, and there is less than 1 degree difference in the warmest and coldest months. 2000-3000 mm annual rainfall. The southeastern islands are exposed to cyclones (tropical low pressure).
Plant and wildlife in the Solomon Islands
There are still rainforests on the largest islands. However, most of the forest has been removed and replaced by a grass-like savannah landscape. Along the coast and on smaller islands the vegetation consists of shrubland, with mangroves and coconut trees closest to the sea. Along the watercourses, screw palm trees often grow.
54 mammal species from three orders: bats, rodents and marsupials (a couscous). Many native (endemic), including more than 10 bats and three large nude rats that climb trees and eat coconuts. The marine mammals include dugong (sea cow) and several whales, i.e. humpback whales.
The bird life is very species rich to be island fauna. 285 bird species have been observed. As many as 70 of these are native, including. brown-tailed eagle, mermaid hawk, white-headed pigeon, fighting owl, 5 fan tails and 10 monarchs. Many similarities to New Guinea and Northern Australia’s bird fauna: Oven hen, frog mouth, parrots and fruit pigeons. Of the seabirds are tropical birds, silkets and nodules.
70 reptiles, including 5 sea turtles and at least 20 snakes, several of which are poisonous. The lizards are represented by varans, geckos and hams, several native. The Delta Crocodile has been subjected to heavy hunting pressure, only 200 remaining individuals in three locations. More than 20 amphibians, including frogs in the genus Rana. Among invertebrates are 130 day butterflies (35 native) and toxic species such as school openers and scorpions.
