Hystad- the black alder forest
One of the biggest black alder forests in the country is in Hystadmarkjo. Along the well prepared trail through the forest you can experience an exceptional nature with an unusual abundance of exuberant plant species. But what has laid the foundation for this richness?
Ådlandsvatnet
Plants that grow in and beside water have to be prepared for marked and rapid changes in their living conditions. They must be able to tolerate living under water without drowning, and getting totally dried out without whithering. Many swamp plants are well adapted to these kinds of changes.
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.
Rambjøra
In Sanddalen and Helldalsåsen the building of houses has increased dramatically. Where there eariery was grazing land, hundreds of families now live. Not far away, lies Rambjøra as an oasis in the built up area.
