Abstract The Late Neolithic pile‐dwelling of Palù di Livenza yielded archaeological remains typical of the Square Mouth Pottery and Lagozza Cultures. A palynological investigation reveals important changes in the vegetation due to anthropogenic pressure. Between ca. 6590 and 5960 cal. yr BP, dense oak wood forests with deciduous Quercus , Fagus and Corylus extended around the mire, with no signs of human impact. The establishment of the pile‐dwelling, dated to ca. 5960 cal. yr BP, led to a strong reduction of forests, reclamation of wetlands, and expansion of herbaceous communities, with cultivated species, infestant weeds, nitrophilous and ruderal herbs, pastures and meadows. According to AMS dates and previous archaeological chronologies, the pile‐dwelling persisted for about 700 years (from ca. 5960 to 5260 cal. yr BP). The history of the pile‐dwelling after ca. 5260 cal. yr BP cannot be reconstructed because of recent contamination of the top part of the section. Rarefaction analysis was applied to estimate changes of palynological richness through time: the highest E ( T n ) (between 56 and 69 taxa) are contemporaneous with the local development of the pile‐dwelling. The comparison of pollen data with archaeobotanical evidence indicates that Fragaria vesca , Malus sylvestris , Papaver somniferum and Physalis alkekengi were gathered at some distance from the site and that Linum usitatissimum is strongly under‐represented in pollen samples. Crop cultivation can be estimated for a radius of several hundred metres around the mire. Palù di Livenza is significant in the context of Neolithic archaeobotany of northern Italy and neighbouring countries. Copyright © 2004 John Wiley & Sons, Ltd.
