Monuriki

Monuriki is a small, uninhabited island situated off the coast of Viti Levu in the Fiji Islands, in Melanesia in the South Pacific Ocean. Monuriki is part of the Atolls islands, and related to a group of three islets in the larger group of islands known as the Mamanuca Islands. This coral and volcanic island is the smallest islet and the southernmost of a small group of three islets, west of Tavua.

Monuriki is of volcanic origin, with a length of 1.15 kilometres (0.71 mi) and a width of 600 metres (660 yd). The land area is approximately 0.4 square kilometres (100 acres) surrounded on all sides by coral reef. The highest point is 178 metres (584 ft). The terrain includes volcanic rocks, lagoons, palm trees, a pine forest, and several small white sand beaches.

The people of Yanuya are the custodians of Monuriki. With the agreement of the Mataqali Navunaivi of Yank village the National Trust of Fiji wild-life experts and other representatives from BirdLife International and Nature Fiji, NTF, with colleagues from the non-government organization BirdLife International, have been restoring the habitat on Monuriki since 2011.

Monuriki has a length of 1.15 kilometres (0.71 mi) and a width of 600 metres (660 yd). The island is mountainous, reaching a maximum height of 178 metres (584 ft) in the south-east. The land area is approximately 0.4 square kilometres (100 acres) surrounded on all sides 360° by coral reef. The terrain includes volcanic rocks, lagoons, palm trees, a pine forest, and several small white beaches.

The vegetation consists mainly of higher pandanus, coconut, (Cocos nucifera) and associated species of coastal forests. The low vegetation has been eroded in the past by herds of goats up on the rocks, decreasing the availability of food to the indigenous iguana population. There is a captive breeding program for iguanas, being run at Kula Eco Park by the National Trust of the Fiji Islands (NTF) and funded by the Critical Ecosystem Partnership Fund (CEPF).

Monuriki is one of the few places on which the endangered Fiji crested iguana, or Brachylophus vitiensis, live. These iguanas feed on a wide range of plants and insects, and spend most of their time camouflaged in the branches of trees. Only a few thousand Fiji crested iguanas live on the three tiny islands of western Fiji: Yadua Tabu, Macuata and Monuriki.

The Brachylophus vitiensis was first featured in a film when Dr. John Gibbons, of the University of the South Pacific, was invited to the screening of the movie Blue Lagoon. The director filmed part of the movie on a remote island, and included shots of the native wildlife to enhance the feel of the movie, including a large colorful iguanid. Gibbons, who had been studying the Fiji banded iguana at the time, travelled to Monuriki and identified it as a distinct species. The species only lives in dry forest habitats, which are one of the most threatened vegetation types in the Pacific. The species was once known to live on 14 islands in the western part of Fiji; however, recent surveys between 2002 and 2004 have only confirmed the species to be living on three islands: Yadua Tabu, Monuriki, and Macuata. Yadua Tabu holds the highest proportion of the species, containing approximately 98% of all individuals, an estimated 6,000 animals. The Yadua Tabu iguanas are the only legally protected population, as Yadua Tabu is a National Trust of Fiji reserve and lacks the feral goats which have destroyed the lizard's habitat on other islands. Monuriki is also a breeding ground for some sea turtles.

The forests in smaller, offshore, islands are tropical and subtropical dry broadleaf forests, which are highly vulnerable to being burnt, as well as being vulnerable to deforestation; overgrazing and exotic species can also quickly alter natural communities. Restoration of the forests is possible but challenging, particularly if degradation has been intense and persistent. Degrading dry broadleaf forests often leave thorny shrublands, thickets, or dry grasslands in their place. Tropical dry forests include both deciduous and semi-deciduous forests. A recent work by Howard Nelson suggests that areas which were formerly classified as evergreen forest also fit the criteria for dry forests.
