The Samoan tropical moist forests are a tropical moist broadleaf forest ecoregion in the Samoan Islands. They cover an area of 3,100 km2 (1,200 sq mi).

The Central Savai'i Rainforest, comprising an area of 727 square kilometres (281 sq mi) on the island of Savai'i in the Samoan Islands, is the largest continuous patch of rainforest in Polynesia. The area contains more than 100 volcanic craters including recent lava flows. There are three broad types of rainforests, the most extensive is lowland forest, followed by montane and cloud forest.[1] The rainforest spans the inland region of the island and contains most of Samoa's endemic native species, many of which are threatened or near extinction.[2]

These include the rare and unusual tooth-billed pigeon (Didinculus strigirostris) known locally as manumea, the national bird of Samoa and other birds such as the maomao honeyeater[2] (Gymnomyza samoensis). The Samoan white-eye (Zosterops samoensis) and Samoan moorhen (Gallinula pacifica) are both endemic to Savai'i. The Samoan moorhen was last recorded in 1873 with possible sightings in 1984 at the upland forests and at Mount Silisili in 2003.[3]

In 1994, Samoa ratified the international and legally binding treaty, the Convention on Biological Diversity to develop national strategies for conservation and sustainable use of biological diversity. As of 2010, protected areas in the country covered 5% of land.[4]

Approximately 30% of Samoa's biodiversity is endemic, found only in Samoa, with new species still being discovered including two new butterflies in 2009 and freshwater fish new to science. The country has more native species of ferns and butterflies than New Zealand, a country 85 times larger.[2]

Most of Samoa's land is under customary ownership, about 81% of which is governed at the local level by matai, the chiefly heads of families.[5] Conservation projects therefore take place in partnership with matai, such as the lowland rainforest preserve in Falealupo village, at the western tip of Savai'i and Tafua village on the south east coast.
