    Local people's involvement in the management of conservation initiatives is central to ongoing debates on the relative merits of distinct biodiversity conservation models. Since different governance models provide distinct opportunities for local people to participate in the management of protected areas, their knowledge of these governance models and motivation to collaborate will vary. This paper analyses cognisance and participation in (1) government-imposed biosphere reserves and (2) community conservation areas, in which ecotourism projects take place.
