The Wolschwiller Directed Biological Reserve
In the heart of the Alsatian Jura, the Wolschwiller Directed Biological Reserve covers 67 hectares and serves as a true open-air natural laboratory. This site is distinguished by its remote limestone cliffs and strikingly beautiful landscapes, offering breathtaking views of the region.
Its geographical position gives it major ecological importance, notably through cross-border management with Switzerland, thus enhancing its environmental value far beyond its limited municipal boundaries in Wolschwiller. The reserve hosts unique natural habitats in Alsace, such as rare limestone cliffs and rock outcrops. The wildlife is equally remarkable, with rare bird species like the Eurasian eagle-owl, peregrine falcon, and common raven.
On the flora side, over 350 plant species have been recorded, including some regionally protected ones like mountain alyssum, Cretan sea holly, and scorpion vetch. Others, such as the moss Grimmia teretinervis, are exceptional and had never been reported in the region before. Careful forestry is practiced around the cliffs to preserve the habitat balance, with particular attention to conserving dead and hollow wood, essential for biodiversity. Among the notable trees, a Scots pine over 200 years old, with twisted branches and a bonsai-like shape, dominates a steep cliff overlooking the village of Wolschwiller.
Beneath this same cliff lies a cave linked to a local legend: it is said to have sheltered the refractory priest Joseph Enderlin, who clandestinely carried out his ministry there after the French Revolution. However, it is imperative not to approach the edge, as the site is not secured.
