The Hawaiian Islands are home to some of the world’s most endangered forests.  The most endangered dry forests are on the island of Oahu, which contains less than 0.2% native dry forest (1.7 km2) with less than 30% protected in reserves (0.5 km2).  A total of 68 native tree and shrub species have been identified in the dry forest region of Oahu and 45% have been identified as threatened species according to the IUCN and U.S. Fish and Wildlife Service.  Since 2000, thirteen organizations (federal, state, private) have been involved in restoration efforts of Hawaiian dry forests at 18 locations in Oahu.  However, additional extensive restoration efforts are still needed in mixed native and non-native dry forests on Oahu and in low elevation urban and rural areas.  The restoration of this forest type will be of central importance to removing species from threatened and endangered species lists and preventing additional species from being listed.
