Hühnerfeld, Nature reserve in Staufenberg, Germany.

Hühnerfeld is a 52-hectare nature reserve protecting a fen in the Kaufunger Wald, between the Kleiner Steinberg (541.9 m) to the east and the Hühnerfeldberg (418.4 m) to the west, at 380 to 460 m elevation. A 1.2-metre-wide wooden boardwalk built in 2015 crosses the southern part west to east on a gradient of about 11%, with a viewing platform near its midpoint.

The area became a protected reserve in 1968 after the moorland faced damage from drainage efforts intended to support forestry following World War II. This protection halted further environmental decline in this fragile landscape.

The name derives from Hünenfeld, an old term for a free open area in the mountains. From the Middle Ages until the mid-20th century, the moor was used as common pasture for livestock, which shaped its open character. Since 1993 it has been grazed extensively with Icelandic horses, and since 2005 also with mother cows, to maintain the habitat for rare plants.

The boardwalk built in 2015 is the main way to explore this protected area and prevents damage to the sensitive moorland. The path is easy to follow and lets visitors reach different sections on foot.

The reserve is grazed by Icelandic horses since 1993 and, from 2005, additionally by mother cows, a management commissioned by the Göttingen district. The grazing keeps the mat-grass and small sedge communities open for species such as round-leaved sundew and white beak-sedge. Visitors on the boardwalk look across the pasture rather than walking among the animals.
