Kahoolawe Island (20° 35' N - 156° 35' W) lies in the rain shadow of the nearby Mount Haleakala on Maui and is consequently drier than most of the other main islands.  During World War II, the military began using the island for target practice and continued to bombard the place for decades.  Finally, in 1993, the island was transferred to native Hawaiian control and a commission was formed to oversee the cleanup and restoration of the island with the goal of revitalizing the native ecosystem and providing for traditional Hawaiian cultural use.
