Lysekloster- The monks and nature
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.
Lysekloster- Mushroom flora
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.
Ulven
In the region of Ulven phyllite occurs with Hordaland's youngest fossils, and a beautiful quartz conglomerate. The phyllite and conglomerate got squeezed into the bottom of an ancient oceanic crust, made of gabbro and greenstone, in the heart of the Caledonide mountain chain.
Ulvenvatnet
Lake Ulvenvatnet is thought to be the most species rich wetlands in the municipality. Despite this, the area is not protected, nor is it likely ever to be.
Finnås
At Flintaneset by Finnåsvika, in the centre of the municipality, we find the most beautiful and best preserved igneous rocks in western Norway. We must go to Hawaii or Island to find as fine structures as at Bømlo.
