Islands until separation on 1 October 1975, is a particularly remote group of islands in the Central Pacific. There are nine islands, five of which are atolls and four reef-top islands on a reefal platform. The vegetation and flora of these islands have received little attention.

Healthy marine resources require healthy, intact ecosystems. Marine and coastal ecosystems are highly productive and deliver various goods and services that support communities and economies, including food security, clean water, recreational
opportunities and other benefits. Effective area-based protection, through MPAs, helps maintain ecosystem health and productivity, while safeguarding social and economic
Mangroves are trees that live halfway between land and sea. This is what makes them special; as for most plants salt water is deadly. Mangroves are among the few trees that can grow in seawater and in places where the seawater mixes with the fresh water from the land.
In Samoa, most of the mangroves grow in areas protected by coral reefs. They are found in coastal areas, especially in river estuaries - the wide lower part of a river's lower end
where it meets the sea.

The colonization of the lagoon by coral reef fish larvae was compared between two islands of French Polynesia, the atoll of Rangiroa and the high volcanic island of Moorea. In both cases the larval flux coming into the lagoon followed a daily cycle.
The islands of the southern Cook and Austral groups in
the South Pacific exhibit astonishing differences in geology
and topography, even between closely adjacent islands of
similar ages. Some are sea-level atolls, others have low
fringes of Pleistocene raised reefs, and others substantial
rims of elevated mid-Tertiary limestones, locally known as
makatea. On some islands the relief of the makatea is
subdued, but on others it is dominated by eroded volcanics,
sea-level swamps, and vertical limestone walls. Sixty years
