Granvinsvassdraget

After the ice age, Granvin Fjord reached all the way up under Skjervsfjossen waterfall. Just a thousand years later, as a result of the rising of the land after the ice melted, this whole inner part of the fjord freed itself of the sea and became Granvinsvatnet lake. In spite of this rise in elevation, this waterway is still navigable for fish: Sea trout have wandered into Granvinsvatnet in more recent times and evolved to become freshwater trout. And salmon and sea trout made the journey 13 kilometres up the Storelvi river.

Joberget

Flowering lime is one of nature's blessings: The nectar gives clear honey. The flower is used as folk medicine. From the inner bark of the lime tree one can make strong rope. Elderly folk can still tell how they got a weather report from the lime tree. If it smelled strong, it was probably going to rain. Lime often grows together with elm, ash and other tree species of the deciduous forest. Pure lime forests are rarer. Granvin has Hordaland's biggest lime forests.

Nedre Folkedal

For many years the Folkedal scythe had a good reputation. Immediately above the highway through Folkedal there is a long brick building, on the inner side of the river. Here production of scythes went on to the beginning of the 1950s.

Uranes

One of the most magnificent deciduous forests in Hordaland grows along the border with Kvam. The rich growth comes from the phyllite and mica schist bedrock, together with a good climate. Along the fjord the summer is warm but not too dry, and in winter it is not too cold for plants that do not tolerate the frost.

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.

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.
