Rabengrund von Wiesbaden, Protected natural area in Sonnenberg district, Wiesbaden, Germany.

Rabengrund is a protected natural area in Wiesbaden that combines meadows, beech forests, and reed beds across varied elevations. The landscape features several vegetation types, including rare acidic grasslands that create habitats for specialized insects.

The area was shaped by agriculture whose origins trace back to Roman times, when it served as farmland. Later human activities further influenced the vegetation patterns that now characterize the protected reserve.

The reserve's orchids include the broad-leaved helleborine, the small orchid, the burnt orchid and the two-leaved forest hyacinth. The green hohlzunge has its only site in the Taunus here. The autumn lady's-tresses was last seen flowering in 2001 and is considered extinct locally.

A nature trail circles the area, allowing visitors to explore different habitats and water sources on foot. The path is designed for those interested in observing the varied plant life in natural conditions.

The green hohl tongue orchid (Coeloglossum viride) has its only site in the Taunus here. The autumn ladies'-tresses still numbered over 100 specimens in 1985, but the last flowering plants were seen in 2001 and it is now considered extinct in the area.
