I Kvassdalen var det aktiv stølsdrift med mjølking av kyr og geitehald nokre år inn i vårt tusenår, og slik hadde det vore i meir enn to hundre år. Såleis har dalen ikkje fått gro til med kratt og skog, men er open og lys. Fortsett er det beiting av kyr og sauer.
Freezing and thawing are processes that influence plant cover, move enormous blocks, stretche long mounds of earth, break open bedrock and create patterns in stone and earth.
Deep down between the stone polished phyllite bedrock in Bordalsgjelet canyon, there is a cascading river. In close cooperation with hard polishing stones, the water has carved into the bedrock for thousands of years - and is still doing so today.
Lurekalven is an unpopulated island of heather moor which is a part of the wilderness belonging to the five farms on Ytre Lygra. Between the two islands there is only a small sound. As late as the 1920s, milking cows were rowed over the sound from Lygra in summer – a form of farming that was adapted to the coastal landscape.
The peat bogs on Toska have been mined for peat since 1946, when the island got electricity. In this treeless coastal landscape, peat was the most important source of energy, and this took quite a toll on the bogs.
