  abstract = {{T}he central {C}ongo {B}asin contains the largest known peatland complex in the tropics. {H}ere we present a detailed multi-proxy record from a peat core, {CEN}-17.4, from the centre of a 45 km wide interfluvial peatland ({E}kolongouma), the first record of its kind from the central {C}ongo peatlands. {W}e use pollen, charcoal, sedimentological and geochemical data to reconstruct the site's history from the late {P}leisto-cene to the present day. {P}eat began accumulating at the centre of the peatland-19,600 cal {BP} (-17,500 e 20,40 0 cal {BP}, 95% confidence interval), and between-9500 (9430e9535 cal {BP}) and 10,500 (10,310 e 10,660 cal {BP}) cal {BP} towards the margins. {P}ollen data from the peatland centre show that an initial grass-and sedge-dominated vegetation, which burned frequently, was replaced by a {M}anilkara-type dominated flooded forest at -12,640 cal {BP}, replaced in turn by a more mixed swamp forest at-9670 cal {BP}. {M}ixed swamp forest vegetation has persisted to the present day, with variations in composition and canopy openness likely caused at least in part by changes in palaeo-precipitation. {S}table isotope data (d{D}n-{C}29-v&icecorr) indicate a large reduction in precipitation beginning-5000 and peaking-2000 cal {BP}, associated with the near-complete mineralization of several metres of previously accumulated peat and with a transition to a drier, more heliophilic swamp forest assemblage, likely with a more open canopy. {A}lthough the peatland and associated vegetation recovered from this perturbation, the strong response to this climatic event underlines the ecosystem's sensitivity to changes in precipitation. {W}e find no conclusive evidence for anthropogenic activity in our record; charcoal is abundant only in the {P}leistocene part of the record and may reflect natural rather than anthropogenic fires. {W}e conclude that autogenic succession and variation in the amount and seasonality of precipitation have been the most important drivers of ecological change in this peatland since the late {P}leistocene.},
