In the mountains, the rough climatic conditions (cold, wind...) prevent the forest from growing beyond an altitude of 2200 metres. Above this level, only grasses resist. Although it may appear rough and homogeneous, this ecosystem is actually extremely rich. Beyond the multiple plant species (such as carlina, lotus, blue gentian, clover, etc.), there are many insects (such as the famous Siberian cricket), mammals (marmots, voles, stoats) and birds (rock ptarmigans and rock partridges).
