Resumen:
The biomisation method is used to reconstruct Latin American vegetation at 6000 +/- 500 and 18 000 +/- 1000 radiocarbon years before present ((14)C yr BP) from pollen data. Tests using modern pollen data from 381 samples derived from 287 locations broadly reproduce potential natural vegetation. The strong temperature gradient associated with the Andes is recorded by a transition from high altitude cool grass/shrubland and cool mixed forest to mid-altitude cool temperate rain forest, to tropical dry, seasonal and rain forest at low altitudes. Reconstructed biomes from a number of sites do not match the potential vegetation due to local factors such as human impact, methodological artefacts and mechanisms of pollen representivity of the parent vegetation. At 6000 +/- 500 (14)C yr BP 255 samples are analysed from 127 sites. Differences between the modern and the 6000 +/- 500 (14)C yr BP reconstruction are comparatively small; change relative to the modern reconstruction are mainly to biom
