The role of climate, forest fires and human population size in Holocene vegetation dynamics in Fennoscandia
QuestionsWe investigated the changing role of climate, forest fires and human population size in the broad-scale compositional changes in Holocene vegetation dynamics before and after the onset of farming in Sweden (at 6,000cal yr BP) and in Finland (at 4,000calyr BP).LocationSouthern and central Sw...
