Neye-Oberlauf, Nature reserve in Wipperfürth, Germany.

Neye-Oberlauf is a 59.6-hectare nature reserve northeast of Wipperfürth, designated in 2013 under key number GM-095. It covers the upper courses of both Neye arms: Neye I with its tributaries near Forste, Halkenberg and Ritterlöh, and Neye II with the Vossebrechener Bach. Straightened spring streams are lined with tall herbaceous vegetation and alder; the Neye I is regaining natural flow dynamics, and its floodplain holds fallow wet meadows and reedbeds.

The area was designated as a protected reserve by the German government in 2013 under IUCN Category IV classification. This status aimed to safeguard habitats and species diversity in the region.

The reserve's name comes from the Neye stream, whose two upper arms, Neye I and Neye II, meet at Unternien. Near the hamlet of Obernien lies a Streuobstweide, a traditional orchard pasture with old, well-tended pear and apple trees. The wet meadows are kept open by extensive grazing and mowing rather than being left to scrub.

Visitors can explore the area using the designated walking paths that lead through the valley and connect different habitats. Wearing appropriate footwear is advisable since some areas can be damp and soft.

The reserve protects only the Vossenbrechener Bach and the Neye II from its confluence onward; the Neye I instead flows around the fish ponds east of the Neyetalsperre, while the Neye II passes them on the west before being diverted into the Neye I.
