When high school student Arne Handegard collected plants for a herbarium in 1962, he didn’t know what kind of rarity he had pressed into his notebook. 30 years later he attended a botanical lecture, where a picture was shown of a plant he recognized: “Norwegian Sagebrush, which in Norway is only found in a large area of Dovre and in Trollheimen, and in a little area in Ry county”. Arne Handegard raised his hand: “That plant grows on Mt. Jonstein in Jondal”.
Yddal is one of the biggest and finest pine forest areas in the county. The rich forest resources provided an important foundation for the settlement of Yddal. Up until about the 1950s, there were three farms here. Where the lumberjacks couldn't get to, the trees grew very big and can be over 300 years old.
Many mountain plants are well prepared to face cold and wind. Some would surely rather face an easier life in the lowlands, but they cannot compete with the higher-growing plants living there. Most mountain plants manage to compete for light and space only if they cling to the bedrock and gravel in the harsh high alpine climate.
