HAWAIIAN RAIN FOREST ECOLOGY
- common, sometimes dense shrub in undisturbed rain forest and the most abundant native shrub in Niaulani Rain Forest
- although the female plants produce fruits, kanawao mostly spreads by sprouts emerging from underground roots
- kanawao is disturbed by feral pigs who uproot and damage the roots that produce new upright stems
- fencing in the 20th century at Niaulani helped protect this species at Niaulani which is uncommon in surrounding areas
- kanawao grows taller than kahili ginger and so survived four decades of ginger dominance in the understory
- in Niaulani, without pigs or ginger, the 15 or so scattered, surviving kanawao colonies are now expanding by root sprouts, with noticeable numbers of young, short, upright stems
