Research in political ecology has paid inadequate attention to the multifaceted cultural politics surrounding discourses of environmental conservation in the developing world. Specifically, it has tended to neglect the rich politicized moral geographies integral to conservation debates. This paper, then, makes the case for thinking about conservation as an envisioning process sensitive to these politicized moral geographies as well as their linkages to political and economic processes. After a brief critique of political ecology, the paper sketches a theoretical approach in which environmental conservation is understood as a process of envisioning social relations, moral discourse and socionatural place. The approach is used to explain two contrasting visions of conservation based on the notions of integrated protected areas management and ancestral domain which are prominent today in the Philippines. The conclusion reiterates the call for a discursive political ecology alive to the politicized moral geographies that condition conservation trajectories. (C) 2000 Elsevier Science Ltd.
