  abstract = {{T}he reliability of paleovegetation records inferred from soil phytolith assemblages and {SOM} (soil organic matter) carbon isotope analysis was examined in light of previous pollen and charcoal reconstructions. {T}he sampled latosol is located in {S}outh-{C}entral {B}razil ({S}alitre), at a boundary between forest and cerrado. {T}he derived mean age of phytoliths and {SOM} at each level is the result of a balance between continuous translocation and selective dissolution. {I}t increases with depth in a regular, quantifiable fashion that allows paleoenvironmental interpretation. {P}hytoliths and {SOM} tracers first record a savanna phase, assoicated with the last {H}olocene long dry period occurring between ca. 5500 and 4500 yr {B}.{P}. {T}wo periods of tree community development followed, between ca. 4000 and 3000 and after ca. 970 yr. {B}.{P}., leading to the present cerrado/forest association. {T}he dry spell interrupted this trend about 970 + or - 60 yr. {B}.{P}. {T}he second development of woody elements was contemporaneous with an increase in anthropogenic fires. {T}herefore, climate was more important than fires and human activities in constraining the growth of vegetaion during the last nine centuries at {S}alitre. {M}ore generally, despite pedogenic processes, soil pytholiths and delta(exp 13) {C} values of the {SOM} may be accurate tracers of vegetation changes.
