The Hawaiian Islands comprise a total of 137 islands and atolls, with a total land area of 16,636 km² (6,423.4 square miles).
Hence the islands in the northwest of the archipelago are older and typically smaller, due to longer exposure to erosion.

 Endemism in the Hawaiian Islands - Wikipedia, the free encyclopedia
On a single island, the climate can differ around the coast from dry tropical (< 20 in or 500 mm annual rainfall) to wet tropical; and up the slopes from tropical rainforest (> 200 in or 5000 mm per year) through a temperate climate into alpine conditions of coldness and dryness.
Note that, simply because of the relatively small area involved, many Hawaiian species are considered threatened even when at their normal population levels.

The Hawaiian Is- lands have seen the most tsunamis, a result of their central location relative to areas of seismic activity around the Pacific Rim and the lack of any energy-absorbing shelves around the group.
Most of the islands of this group are only a few meters in elevation, and the combined effect of higher sea level during the mid- and late-Holocene with tsunamis helps explain why this group has fewer endemics than we predict based on its size and topography.

The higher level of endemism in Hawaii as compared with that in the Galápagos stems from the combined effects of the more isolated geographical position, the more varied ecological conditions, and the greater geological age of the Hawaiian chain.
Floras of isolated oceanic islands are typically dominated by plant families characterized by good dispersal ability, although the descendents now present on an island may have lost adaptations to long distance dispersal.
Both the Galápagos and the Hawaiian islands are famous for outstanding examples of adaptive radiation in several groups of organisms.
