From a geological point of view, limestones and dolomites constitute the bedrock of Mt. Kalon Oros. The slopes of south and southwest exposure have steep gradients whilst all other slopes are characterized by gentle gradients. The vegetation cover presents a low diversity since it is mainly composed of macchia with the dominant species of Quercus coccifera, Pistacia lentiscus and Arbutus unedo. Macchia vegetation is very dense on eastern and northern exposed slopes, while on the south and southwestern slopes it is very sparse. In higher altitudes up to the peak, rocky grasslands with sparse individuals of Quercus coccifera occur on the west exposed slopes. These areas were cultivated in the past (olive trees, vineyards) but are now abandoned. Source: Natura2000 viewer, European Comission.
