Over time strawberry guava displaces native Hawaiian rainforest. These photos show a typical sequence from upper elevations that have not yet been overrun by strawberry guava to lower elevations where the native species have been severely impacted and, in the end, replaced completely. The sequence is along a trail in the Hawaii Experimental Tropical Forest, Laupahoehoe unit (Laupahoehoe Natural Area Reserve) on Hawaii Island. Photos by Christian Giardina, US Forest Service
