In the early 1900s, the US Forest Service planted more than 100,000 Molucca Albizia seedlings in the Hawaiian Islands. The aim of introducing the nonnative trees was to reforest and beautify the islands.
But while the trees' canopy provides needed shade for coffee and tea plants in parts of Southeast Asia, in the Hawaiian Islands, Molucca Albizia trees now pose what the state's legislature calls a "significant hazard to people and property in various residential and recreational areas." The wood is weak.
During storms or high winds, the trees sometimes uproot or their branches break off, causing property damage, bringing down power lines, and endangering people's lives.
Logan Berner, a Big Island Invasive Species Committee volunteer, used GPS, ArcGIS software, and QuickBird satellite imagery to better determine the extent of the problem posed by the trees in North Hilo on the Island of Hawaii.
