Some Plants of the Lava Rocks of Idar-Oberstein in the Nahe Valley

The mountain in the Nahe Valley at Idar-Oberstein consists of volcanic rock. The southern exposed slopes which can become very warm in summer as well as the northern exposed slopes which are shadowy most time of the day are forming extreme biotopes with own plant societies.

At this northern exposed rock in the city of Idar-Oberstein e.g. still Saxifraga rosacea subsp. sponhemica, Sedum forsterianum, and Hieracium schmidtii can be found, but these are mixed up with plants introduced or ran wild from gardens:

At southern exposed rocks there is extreme heat in summer, and also extreme dryness at many of these rocks, which leads to a meagre and very special plant society:
