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.
On the farm Bø, close to the highway between Bulken and Voss lies Byrkjehaugen, one of the largest burial mounds in West Norway. Originally it was around 50m across and 5m high, but following the excavation in 1908 and chipping off by both railway and road construction, the cross-section has shrunk to 37m and the height to 4m. All the same, it is an impressive burial monument for the passing traveller to see.
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.
