Oceania Plant Geography

The small, low coral islands have a species-poor flora with screw palms, coconut palms and other widespread species. By contrast, on larger coral islands and especially on high islands of volcanic origin, such as Hawaii, Fiji and New Caledonia, the species richness is large, and endemic species make up 70-90% of the original flora. Species in the banana and palm families are prominent just like fig species and tree ferns; the bread fruit tree (Artocarpus) is native to the area.

2012 OceaniaThe latest estimates of the number of plant species are for the Pacific Islands approx. 10,700 species. The largest and most peculiar floras occur in Hawaii (about 1000 species), Fiji (about 1500 species) and New Caledonia (about 3200 species). New estimates for Australia and New Zealand include approx. 25,700 species, and the total figure for Oceania is estimated to be approx. 35,000 species.

New Caledonia has a very distinctive flora. endemic conifers. The very primitive family Degeneriaceae (with a single species, Degeneria vitiensis) is endemic in the Fiji Islands. In Hawaii's flora, there is both an American and a Malaysian element, and significant species formation has occurred on the archipelago itself. Typical of many species developed on oceanic islands are large fruits and seeds and thereby a poor spreading ability.

Fiji's geography

Fiji is located in the southern part of the tropics, between the equator and the sun's southern (Capricorn) turning circle. The largest islands are of volcanic origin, many of the smaller ones are flat coral islands (ancient atolls raised from the sea). The highest peak is the volcano Tomaniivi on Viti Levu, 1323 meters above sea level.

Fiji Climate

Fiji has a tropical ocean climate, where the Southeastern pass moderates the humid heat. The average temperature in Suva (Viti Levu) is 23 C in July-Aug, and 27 C in January-March. Average annual rainfall varies in the different islands from 1400 mm in the west to over 5000 mm in the east. Precipitation is consistently greatest on the southeastern coasts, while the northwestern parts of the islands remain in shelter for the southeastern pass. Suva receives 2975 mm of precipitation a year; March is the driest month and July is the driest.

Fiji traditionally experience an average of 10–15 cyclones per decade. Of these, perhaps one has been of hurricane strength. Since 1985, however, both the frequency of the cyclones, as well as the proportion of these with hurricane strength, have increased.

Plant and wildlife on Fiji

The vegetation follows the climatic pattern of rainforests in the southeast and more sparse forests, reeds and grass in the drier regions.

The only naturally occurring land mammals are bats; The family of flying dogs is represented by several species, including Samoa fly dog, which with wingspan of up to 1.5 meters is one of the world's largest bat species. Many cats, dogs, pigs and goats occur in a lost state. The indiaman gust (see mangosteen) was introduced to fight the rats that humans had also brought. More than 120 bird species have been observed, 90 of these nesting. The nesting birds include storm birds, tropical birds, frigate birds, soles, herons, kingdoms and terns. Among pigeons, parrots and honey eaters there are many native species. A number of bird species have been introduced in recent times. The endangered Fiji iguan (see iguanas) belongs to a lizard family that is otherwise only found in America and Madagascar. A further 20 reptile species occur on land. In the coastal waters there are delta crocodiles and sea ​​snakes, as well as a rich coral reef fauna.
