The role of climate, forest fires and human population size in Holocene vegetation dynamics in Fennoscandia
Abstract Questions We 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 6,000 cal yr BP) and in Finland (at 4,000 cal yr BP). Location Southern...
