In this essay, we highlight the intellectual context that shaped our initial conceptualisation of political forests as dynamic spaces and political ecologies, and how our fieldwork and comparative approach shaped our subsequent elaboration of the concept and its empirical manifestations. Of particular significance was our emphasis on incorporated/relational comparison and our multiscale analysis. These approaches allowed us to locate subjects and processes in specific field sites within an emergent global forestry network produced through multiscale interactions and movements within and among colonial and FAO forestry empires. We revisit the key processes through which we learned to see common and contrasting mechanisms that have made forests inherently political in our six research sites in Indonesia, Malaysia, and Thailand, linking these "classic" mechanisms to concepts in wide use today. These concepts include understanding political forests as co-produced, the significance of expertise in their reproduction, and the interactions between politics and the lively materialities of political forests. Among other conclusions, we suggest that the political forest is being replaced by what could be called "political conservation", which has its own knowledge networks and expertise that displace but also build on political forestry. Finally, we reflect on how these ideas are being further developed by the authors in this symposium, whom we gratefully acknowledge for demonstrating that the politicisation of forests continues to be significant today.
