Rainfall from 1000 mm in the east to 3,000-4,000 mm in the west especially a lot of them falls on the windward slopes of mountainous Islands (the Hawaiian Islands in some places more than 10 000 mm). Glaciers are found in the mountains of New Guinea and the South Island of New Zealand. On the windward slopes of mountainous Islands is dominated by moist evergreen forests, and on the lee - xerophytic hard-leaved forests and shrubs. There are areas of vegetation such as savannas. On ism. Coral Islands - bushes, forest areas, groves of coconut palms, breadfruit, and others. The fauna is poor; very small mammals and many insects and birds.
