Bargerveen Nature Reserve is a nature reserve in the Dutch province of Drenthe that has been included in the Natura 2000 ecological network. Since 2006 it is part of the Internationaler Naturpark Bourtanger Moor-Bargerveen (engl. Bourtanger Moor-Bargerveen International Nature Park), a nature reserve located on both sides of the border between the Netherlands and Germany. Most of the transboundary nature reserve, some 134 km2 (52 sq mi), lies in Germany, in the west of the state of Lower Saxony. The sparsely populated landscape consists of large peat areas, heather, and small lakes.
