Country Background

Geography & Ecosystems

The Samoa consist of 15 scattered islands spread over 2 million km² in the South Pacific. These islands are divided into two main groups: the Southern Group, which is of volcanic origin, and the Northern Group, which is of coral origin. Despite a small land area, the nation boasts a vast exclusive economic zone. The main ecosystems include tropical forests, coral reefs, and coastal lagoons.

Biodiversity

The Samoa ecosystem is characterized by high endemism, particularly among bird and plant species. However, overall biodiversity levels are lower compared to other regions. The coral reefs and marine ecosystems are home to a variety of fish, sea turtles, and invertebrates. The conservation of these endemic species is a top priority.

Invasive Species Threats

Invasive alien species pose a serious threat to the native biodiversity of the Samoa. Rats, cats, and pigs are major predators that have caused a decline in native bird populations. Invasive plant species compete with native flora, altering the structure of ecosystems. The control of these invasive species is essential to protect the fragile ecosystem of the islands.

PRISMSS Partnership

The goal of PRISMSS is to provide technical, financial, and capacity-building support to Pacific island nations to effectively manage invasive alien species. This partnership plays a crucial role in strengthening the Samoa' ability to combat the threats from invasive species.
