Wiesbütt-Moor, Protected nature reserve in Flörsbachtal, Germany

The Wiesbütt-Moor is a spring-fed intermediate moor on the Hesse-Bavaria border at 436 metres, the highest of its kind in the Spessart. It runs about 2 km long and 50 m wide, with peat up to 2 m deep. The Wiesbüttsee lies to the northwest, and the Spessart-Höhenstraße passes about 100 m away.

Around 2,000 years ago the site was a swampy alder carr fed by small springs forming the headwaters of the Aubach. After late-medieval forest clearance removed the natural water storage, the valley floor became waterlogged. In 1765 the Wiesbüttsee was dammed to plans by mining master Johann Philipp Cancrinus for the Lochborn mine near Bieber, raising water levels in the hollow above; peat mosses colonised the nutrient-poor, acidic water and an intermediate moor formed.

The name Judenbörnchen refers to a spring at the moor's edge and comes from Jewish cattle traders who used this water source. This connection to local commerce remains visible in the landscape's name today.

The moor is best explored using the Flörsbacher Panorama trail, a 7.6 kilometer route mixing natural paths, paved roads, and narrow trails. The varied terrain accommodates different fitness levels and hiking preferences.

The moor also shelters glacial plant relics such as Siebenstern, Sparrbinsen and Scheidenwollgras, rare at this latitude, alongside the carnivorous sundew that traps insects for nitrogen. Trees cannot root in the waterlogged peat, and tall perennials fail on its nutrient-poor, acidic ground.
