Tveitavatnet
It is difficult to imagine that a plant can grow at the same place for many thousands of years: Climate and local environment change. Different species grow up and die out. Nonetheless, some plants get established, but don't manage to spread into new areas, because the climate is at the edge of what they can tolerate. Great fen-sedge is just such a plant.
Valldalen
Valldalen or Valdalen, the name that the locals used in past times, had been a permanent settlement for a long time, and later the biggest mountain-farm valley in western Norway. Since that time there have been many changes: Most of the fields are no longer in use. Bjørkeskogen, a birch forest that had grown in the valley for thousands of years, took more and more over. And in the valley bottom, the Valldals dam now keeps the artificially large Valldalsvatnet Lake in place.
