Rethinking Easter Island's ecological catastrophe

Rapa Nui (Easter Island) has become a paragon for prehistoric human induced ecological catastrophe and cultural collapse. A popular narrative recounts an obsession for monumental statuary that led to the island's ecological devastation and the collapse of the ancient civilization. Scholars offer this story as a parable of today's global environmental problems. In this paper, I review new and emerging Rapa Nui evidence, compare ecological and recently acquired palaeo-environmental data from the Hawaiian and other Pacific Islands, and offer some perspectives for the island's prehistoric ecological transformation and its consequences. The evidence points to a complex historical ecology for the island; one best explained by a synergy of impacts, particularly the devastating effects of introduced rats (Rattus exulans). This perspective questions the simplistic notion of reckless over-exploitation by prehistoric Polynesians and points to the need for additional research.
