Rain forest is the only major ecosystem in Hawaii, right?
There are about 150 distinct ecosystem types in the Hawaiian Islands. These ecosystems are so distinctive that the Hawaiian Islands constitute a unique global bioregion. These ecosystems range from tropical dry forest, to subalpine grasslands, snowy alpine deserts, to brackish anchialine pools, subterranean lava tube systems with eyeless creatures, to windswept coastal dunes. The Hawaiian ecological showcase is impressive indeed!
