The article presents an overview of the currently available palaeoecological data on the prehistoric anthropogenic impact on the environment and emergence of farming in the south-eastern Baltic, an area poorly studied in palaeoenvironmental and archaeological terms. The recently obtained palynological data from the lake and bog sediments along with the existing archaeological finds allow us to consider several stages of prehistoric farming in the south-eastern Baltic. The first indications of forest management – the creation of open deforested areas, wood burning and probably cultivation (propagation) of hazel appear during the Mesolithic, 10 300–6500 cal BP. At about 6500–5200 cal BP, evidence of the first agricultural activity and local animal husbandry emerges. From 5200 cal BP onwards, farming probably occupies a permanent place in the subsistence strategy of the ancient population of the south-eastern Baltic.
