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.
At the bottom of the Osa fjord there is a cultural landscape marked by great contrasts; the wide terraces and the river delta at the fjord contrast with the steep hillsides in the background, where Norddalen leads up to the mountain. There are two farms here. Osa and Sævartveit – the farm at the river mouth and the hollow by the sea.
In the sunny, steep fjord landscape along Sørfjorden on the east side of Osterøy is the farm Havrå. The small “hamlet” is one of the few undisturbed farming communities that gives us the impression of the large communal yards in West Norway in the 1700s, with houses built close together and strips of arable land.
Fyksesundet and Botnagrenda present a fine experience of the landscape and cultural history; a geographically isolated local settlement with extensive cultural contact with the outside world.
The farm Nes lies directly inside Mundheim on a forested headland in the fjord between Mundheimsvika and Bondesundet, a farm with an attractive and well-kept cultural landscape.
Lysekloster was the largest agricultural property in the country when it was phased out during the Reformation in 1537. In its prime this cloister encompassed two-thirds of all the farms in Os. The monks introduced and cultivated new plant species and it was probably they who stocked the waters with fish not indigenous to the area. This legacy from the Middle Ages has left a lasting mark.
The area around Lysekloster is one of the most popular places in Hordaland for picking mushrooms. The large variety of mushrooms probably stems from the varied, old, cultural landscape which has a lot of open grazing areas and several types of fir- and deciduous forests.
