Description :
Postglacial vegetation history is investigated by pollen and charcoal analyses of a deep, fjord-like lake, eastern part of Paanajärvi. Dates of events are based on previous palaeomagnetic results. From the oldest phase, 9,800 cal. BP, onwards the periglacial herb-rich vegetation was soon replaced by pine-dominated forests and then by mixed forests including birch and alder. After the spread of spruce at 6,200 cal. BP, the vegetation has consisted of monotonous coniferous forests. Results of DCA ordination suggest increased biodiversity at 1,100 cal. BP, when the first signs of human impact can be detected.
