ABSTRACT- Sabal yapa is used by Yucatec Mayan people for thatch. Ecological-sustainability of the management of this species was evaluated in the context of the fragmented landscape generated by slash-and-burn agriculture. Population dynamics was evaluated in plots of differing successional status. A markovian model of patch dynamics was generated using remote-imaging information. All this information let produced a combined matrix model of patch-specific demography and patch dynamics through which different ecological scenarios were evaluated. Results suggest that the S.yapa metapopulation would be sustainable under current extraction regimes only if mature forest dominates the landscape, but not if agricultural fields becomes dominant in the landscape.
Key words: sustainability, Yucatan, metapopulation, sabal yapa
