The timing and importance of arboriculture and agroforestry in a temperate East Polynesia Society, the Moriori, Rekohu (Chatham Island).

Identifying arboriculture and agroforestry in Polynesian Societies has usually relied heavily upon the ethnographic record in the absence of direct archaeological evidence. In this paper we outline a multi-proxy research design, including ethnography, palynology, anthracology, archaeology and a high precision chronology to evaluate arboriculture and agroforestry as components of Moriori subsistence practices before the arrival of Europeans in 1791. The colonisers of Rekohu brought with them a mainland New Zealand endemic tree, Corynocarpus laevigatus, and the technology to propagate the tree in a less than ideal climate and to process its drupe into a storable source of carbohydrate in what was a difficult environment for Polynesian cultivation practices. We also present a conceptual model of forest change due to Moriori fuel selection practices which suggests that Moriori were actively managing these forest spaces for food, fuel, medicine, construction material and as a habitation space, therefore making agroforestry an important component of Moriori subsistence.
