  abstract = {{T}his paper presents quantitative reconstructions of vegetation and climate along the pollen sequence of {L}ake {B}arombi {M}bo, southwestern {C}ameroon (4 degrees 39'45.75 ' {N}, 9 degrees 23'51.63 ' {E}, 303ma.s.l.) during the last 33 000 cal yr {BP}, improving previous empirical interpretations. {T}he biomisation method was applied to reconstruct potential biomes and forest successional stages. {M}ean annual precipitation, mean annual potential evapotranspiration and an index of moisture availability were reconstructed using modern analogues and an artificial neural network technique. {T}he results show a dense forested environment around {L}ake {B}arombi {M}bo of mixed evergreen/semi-deciduous type during the most humid phases (highest precipitation and lowest evapotranspiration), but with a more pronounced semi-deciduous type from ca. 6500 cal yr {BP} to the present day, related to increased seasonality. {T}his forest displays a mature character until ca. 2800 cal yr {BP}, then becomes of secondary type during the last millennium, probably due to increased human activity. {T}wo episodes of forest fragmentation are shown, which are synchronous with the lowest reconstructed precipitation and highest potential evapotranspiration values. {T}he first of these occurs during the {LGM}, and the second one from ca. 3000 to ca. 1200 cal yr {BP}, mainly linked to high precipitation seasonality. {S}avanna were, however, never extensive within the {B}arombi {M}bo basin, existing instead inside the forest in form of savanna patches. {T}he climate reconstructions at {L}ake {B}arombi {M}bo suggest that the artificial neural networks technique would be more reliable in this region, although the annual precipitation values are likely under-estimated through the whole sequence.},
