There are seven habitats in the area that illustrate human activity during the early Stone Age. At Almeö, the most impressive habitat, the finds include the remnants of flint tools and the remains of a domesticated dog - the oldest Nordic evidence of man's use of dogs. Large numbers of bones, primarily from elk, aurochs and beavers but also from wild boar, red deer, wolf and bear, have also been found. Needless to say, fishing played an important role.
About 6,000 years ago, human beings started cultivating this landscape, with its extensive deciduous forests. This was the start of the farming Stone Age. Most of the habitats from the period are concentrated on the northern and eastern shores of the lake. The first ceramic discoveries date back to this period.
Some 2,000 years ago, the fields and meadows started to spread at the expense of the forest. Iron began to play an important role, as did self-subsistent households. At the same time, the first villages were set up around the lake; they included Tranum, Bjällum, Bolum and Hornborga.The cold climate forced people to gather winter fodder for their cattle. Rich production in flooded water meadows played a vital part.
