Pritchardia viscosa is extremely rare and the four remaining wild plants are highly vulnerable to any chance event that may occur. This species has suffered from habitat destruction and from competition with invasive introduced species such as Rhodomyrtus spp. and Psidium spp. (4). In 1992, Hurricane Iniki swept through the area and destroyed yet more of the remaining plants (1). Today, the biggest threat to the survival of the 4 remaining trees comes from seed predation by rats, pigs or humans (1).
