Dalby Söderskog (which means Dalby South Forest) is a small national park in Scania, a province in southern Sweden. It is located in the municipality of Lund, near the town of Dalby. The park covers an area of 0.36 km² (0.14 mi²) and is made up of broadleaf forest. It was created in 1918 because people believed it was a rare piece of ancient forest. However, the land was used for grazing in the past. The soil contains a lot of limestone and chalk, which supports a wide variety of plant life, especially spring flowers. A hill made of earth with unknown origins, possibly the remains of an old fort, surrounds parts of the park. The national park includes the southern part of Dalby hage, while the northern areas, Dalby Norreskog and Hästhagen, are part of a nature reserve.
