Abstract
Two species of trees, koa (Acacia koa Gray [Fabaceae]) and ‘ōhi‘a lehua (Metrosideros polymorpha Gaud. [Myrtaceae]), are important for reforestation of degraded lands within Hakalau Forest National Wildlife Refuge on the Big Island of Hawai‘i. These species require quite different growing containers and subsequently different planting tools. While dibbles are used for koa planting, a gasoline-powered auger, described briefly herein, is preferred for ‘ōhi‘a and other understory species. Auger planting is more than 2.5 times faster than planting by hand.
