The rock formations primarily consist of fine-grained light beige, yellow, or brown sandstone and soil-sandstone mixtures, often limonitic, with clay layers.

Due to the extensive afforestation of this area, it no longer stands out as prominently as it did in past centuries, when it was consisted primarily of fields and meadows.

The lower gamma layer, about two to three meters thick, consists of calcareous sandstone beds and clay interbedded with sand lenses.

The remaining Brown Jurassic-ε layer, nearly ten meters thick, emerges as light gray, stiffly plastic, calcareous clay.

The lowest two White Jurassic levels α and β form a uniform stock of approximately 25 metres (82 ft) in thickness throughout the Weismain area, including the Kalkberg.

Above the β stage, which is already becoming more flat but still easily distinguishable, the White Jurassic γ layer begins from 430 metres (1,410 ft) above sea level.

The lower elevations are predominantly covered by forests, with the species diversity influenced by the sandy soils of the brown Jurassic rocks of the Dogger β to ε.

From an altitude of about 395 metres (1,296 ft) above sea level, the geological composition of the mountain also changes the vegetation, which is now dominated by the calcareous soils of the White Jurassic α and β rocks.

However, sporadic growth of Scots pines, common juniper, and hackberry can be observed in the extensive areas of rough grassland.

The reading stone bars and dry-stone walls also serve as valuable habitats, supporting various amphibians, insects, and the mouse weasel.

Notably, the summit area is home to the common tiger beetle, a species that is endangered and facing extinction in Germany.

[8] It is also located in the northern part of the 1,021.64 km2 (394.46 sq mi) landscape conservation area of the Franconian Switzerland-Veldenstein Forest Nature Park (LSG No.

[6] To ensure the grazing of the meadows in this traditional form, the landscape conservation association of the district of Lichtenfels has been actively involved for over 15 years in uncovering old sheep herds and creating driving paths.

These measures included enlarging the grassland areas, which significantly improved the habitat for endangered species and contributed to their conservation.
