The central sector of the island is a mountainous and woody environment, characterized by development of sub Antarctic forest as well as by its various environments and microenvironments with different resources. The investigation search to evaluate the interrelationship between environment, resources and population dynamics in this area, that we consider as a key to understand the dynamics of mobility throughout the island. It is organized around hypothesis regarding differential resources supply in the various environments of the area, and the possible circulation of hunter-gatherers, as well as the role of both factors in the variability of the archaeological record.
