Blutsee-Moor, Nature reserve in Irtenberger Forest, Bavaria, Germany

Blutsee-Moor is a protected nature reserve in Irtenberger Forest consisting of several hectares of wetland with floating meadows resting on underground water bodies. The landscape features boggy areas with characteristic vegetation typical of a lowland wetland ecosystem in Lower Franconia.

The sources do not record a protection date for Blutsee-Moor; the wetland lies in the southeastern part of the Irtenberger Wald, within the FFH area Irtenberger und Guttenberger Wald. West of the moor, the large new Naturwald Irtenberger Wald was established. A biotope survey from 1997, number 6225-0060, mapped the site's habitats.

The name Blutsee refers to the irregular appearance of the red-coloured flagellate Euglena sanguinea, which tints the water; the moor is not permanently red. The reserve lies between Limbachshof and Gerchsheim in the southeastern Irtenberger Wald, and its floating mat is the largest in Lower Franconia.

The moor itself is closed to visitors for safety reasons, but marked hiking trails around the perimeter allow you to observe the area. The trails are easy to follow and offer good vantage points for exploring the landscape.
