Oahu and Kauai

The northernmost of the main Hawaiian islands, Oahu and Kauai have strongly contrasting levels of development but pockets of high endemism. The island of Oahu is characterized by the extensive hardscape of urban Honolulu and post-agricultural suburban sprawl. Oahu has a total land area of 596.7 square miles (1,545.4 km2) on which almost a million people live. In contrast, while about the same size (562.3 square miles), Kauai is home to less than 70,000 people. Oldest of the main Hawaiian islands, Oahu and Kauai are approximately 5-6 million years old. PIERC partnership with Department of Interior includes research at the Oahu Forest National Wildlife Refuge and Joseph Campbell National Wildlife Refuge on Oahu and the Hanalei National Refuge on Kauai.
