Mangrove Areas
Nearly 75 percent of the coastlines in the tropics (between 25 degrees north and 25 degrees south) have some kind of mangrove covering. Although most are found within 30 degrees of the Equator some hardy varieties such as those found in New Zealand have adapted themselves to temperate climates.

Mangrove areas worldwide
Mangroves are most prolific in Southeast Asia, where they are thought to have originated, with the largest total area of mangroves in Indonesia. The Indo-Pacific mangroves are generally richer in species and dense growth than mangroves found elsewhere. In parts of Sumatra mangroves are marching into the sea at a rate of 115 feet a year; in Java advance rates of a 180 feet a year have been recorded. There are 60 species in the Indo-Pacific region compared to only 12 in the New World and three in Florida (the red, the black and the white).
Mangroves in the Asia-Pacific region are harvested for wood for paper. They are also excellent land builders. Their interlocking roots stop sediments from traveling out sea and instead cause them to settle around the mangroves. As mud accumulates on the seaward side of a swamp, mangroves advance and claim it using special seeds that germinate while still hanging from a branch. The seeds sends down green spear-like shoots which may up to 40 centimeters long. Some aboriginals in northern Australia believe their primal ancestor used mangroves to walk across the mudflats to bring trees into existence.
